I have an xml doc that I am trying to parse using Etree.lxml

    &lt;Envelope xmlns=&quot;http://www.example.com/zzz/yyy&quot;&gt;
      &lt;Header&gt;
        &lt;Version&gt;1&lt;/Version&gt;
      &lt;/Header&gt;
      &lt;Body&gt;
        some stuff
      &lt;Body&gt;
    &lt;Envelope&gt;

My code is:

    path = &quot;path to xml file&quot;
    from lxml import etree as ET
    parser = ET.XMLParser(ns_clean=True)
    dom = ET.parse(path, parser)
    dom.getroot()

When I try to get dom.getroot() I get:

    &lt;Element {http://www.example.com/zzz/yyy}Envelope at 28adacac&gt;
However I only want:

    &lt;Element Envelope at 28adacac&gt;

When i do 

    dom.getroot().find(&quot;Body&quot;)

I get nothing returned. However, when I
     
    dom.getroot().find(&quot;{http://www.example.com/zzz/yyy}Body&quot;) 

I get a result.

I thought passing ns_clean=True to the parser would prevent this.

Any ideas?



lxml etree xmlparser remove unwanted namespace

I&#39;m way new to working with XML but just had a need dropped in my lap. I have been given an usual (to me) XML format. There are colons within the tags.

    &lt;THING1:things type=&quot;Container&quot;&gt;
      &lt;PART1:Id type=&quot;Property&quot;&gt;1234&lt;/PART1:Id&gt;
      &lt;PART1:Name type=&quot;Property&quot;&gt;The Name&lt;/PART1:Name&gt;
    &lt;/THING1:things&gt;

It is a large file and there is much more to it than this but I hope this format will be familiar to someone. Does anyone know a way to approach an XML document of this sort?

I&#39;d rather not just write a brute-force way of parsing the text but I can&#39;t seem to make any headway with REXML or Hpricot and I suspect it is due to these unusual tags.

my ruby code:

        require &#39;hpricot&#39;
        xml = File.open( &quot;myfile.xml&quot; )
            
        doc = Hpricot::XML( xml )
            
       (doc/:things).each do |thg|
         [ &#39;Id&#39;, &#39;Name&#39; ].each do |el|
           puts &quot;#{el}: #{thg.at(el).innerHTML}&quot;
         end
       end

...which is just lifted from: http://railstips.org/blog/archives/2006/12/09/parsing-xml-with-hpricot/

And I figured I would be able to figure some stuff out from here but this code returns nothing. It doens&#39;t error. It just returns.


Parsing XML with Ruby

I&#39;m getting this error when trying to parse through an XML document in a C# application:

&gt;&quot;For security reasons DTD is prohibited in this XML document. To enable DTD processing set the ProhibitDtd property on XmlReaderSettings to false and pass the settings into XmlReader.Create method.&quot;

For reference, the exception occurred at the second line of the following code:
    
    using (XmlReader reader = XmlReader.Create(uri))
    {
        reader.MoveToContent(); //here

        while (reader.Read()) //(code to parse xml doc follows).

My knowledge of Xml is pretty limited and I have no idea what DTD processing is nor how to do what the error message suggests. Any help as to what may be causing this and how to fix it? thanks...

As far as XML parsing is concerned, which is the best node module, that I can use for XML parsing?

The best node module for XML parsing

I am getting a `System.FormatException` when I try to do the following (as an example):

    TimeSpan ts = XmlConvert.ToTimeSpan(&quot;P72H&quot;);

I&#39;ve investigated the [ISO8601 Standard](http://en.wikipedia.org/wiki/ISO_8601#Dates) and it seems to be correct, but I cannot get it to parse hours without throwing an exception, no matter what I do.

Thanks!

EDIT: 

Exception detail:

    System.FormatException was unhandled by user code
    HResult=-2146233033
    Message=The string &#39;P72H&#39; is not a valid TimeSpan value.
    Source=System.Xml

How do I convert an ISO8601 TimeSpan to a C# TimeSpan?

I read some articles about the **XML** parsers and came across **SAX** and **DOM**.

 **SAX** is event-based and **DOM** is tree model -- I don&#39;t understand the differences between these concepts. 

From what I have understood, event-based means some kind of event happens to the node. Like when one clicks a particular node it will give all the sub nodes rather than loading all the nodes at the same time. But in the case of **DOM** parsing it will load all the nodes and make the tree model. 

Is my understanding correct? 

Please correct me If I am wrong or explain to me event-based and tree model in a simpler manner. 

What is the difference between SAX and DOM?

I&#39;m looking for an HTML Parser module for Python that can help me get the tags in the form of Python lists/dictionaries/objects.

If I have a document of the form:

    &lt;html&gt;
    &lt;head&gt;Heading&lt;/head&gt;
    &lt;body attr1=&#39;val1&#39;&gt;
        &lt;div class=&#39;container&#39;&gt;
            &lt;div id=&#39;class&#39;&gt;Something here&lt;/div&gt;
            &lt;div&gt;Something else&lt;/div&gt;
        &lt;/div&gt;
    &lt;/body&gt;
    &lt;/html&gt;

then it should give me a way to access the nested tags via the name or id of the HTML tag so that I can basically ask it to get me the content/text in the `div` tag with `class=&#39;container&#39;` contained within the `body` tag, or something similar.

If you&#39;ve used Firefox&#39;s &quot;Inspect element&quot; feature (view HTML) you would know that it gives you all the tags in a nice nested manner like a tree.

I&#39;d prefer a built-in module but that might be asking a little too much.

I went through a lot of questions on Stack Overflow and a few blogs on the internet and most of them suggest BeautifulSoup or lxml or HTMLParser but few of these detail the functionality and simply end as a debate over which one is faster/more efficent.

I tried reading the document at http://effbot.org/zone/element-namespaces.htm but I am still not able to get this working since the above XML has multiple nested namespaces.

Kindly let me know how to change the code to find all the `owl:Class` tags.

Parsing XML with namespace in Python via &#39;ElementTree&#39;

I have used the XML Parser before, and even though it worked OK, I wasn&#39;t happy with it in general, it felt like I was using workarounds for things that should be basic functionality.

I recently saw SimpleXML but I haven&#39;t tried it yet. Is it any simpler? What advantages and disadvantages do both have? Any other parsers you&#39;ve used?

Best XML Parser for PHP

How can one parse HTML/XML and extract information from it?

How do you parse and process HTML/XML in PHP?

A while ago, I started on a project where I designed a html-esque XML schema so that authors could write their content (educational course material) in a simplified format which would then be transformed into HTML via XSLT. I played around (struggled) with it for a while and got it to a very basic level but then was too annoyed by the limitations I was encountering (which may well have been limitations of my knowledge) and when I read a blog suggesting to ditch XSLT and just write your own XML-to-whatever parser in your language of choice, I eagerly jumped onto that and it&#39;s worked out brilliantly.

I&#39;m still working on it to this day (_I&#39;m actually supposed to be working on it right now, instead of playing on SO_), and I am seeing more and more things which make me think that the decision to ditch XSLT was a good one.

I know that XSLT has its place, in that it is an accepted standard, and that if everyone is writing their own interpreters, 90% of them will end up on [TheDailyWTF](http://thedailywtf.com). But given that it is a [functional style language](http://en.wikipedia.org/wiki/Functional_programming) instead of the procedural style which most programmers are familiar with, for someone embarking on a project such as my own, **would you recommend they go down the path that I did, or stick it out with XSLT**?

Is XSLT worth it?

I am trying to parse xml which contains the some non ASCII cheracter, 

the code looks like below

    from lxml import etree
    from lxml import objectify
    content = u&#39;&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;&lt;div&gt;Order date &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160; &#160;: 05/08/2013 12:24:28&lt;/div&gt;&#39;
    mail.replace(&#39;\xa0&#39;,&#39; &#39;)
    xml = etree.fromstring(mail)

but it shows me error on the line &#39;content = ...&#39;
like 

    syntaxError: Non-ASCII character &#39;\xc2&#39; in file /home/projects/ztest/responce.py on line 3, 
    but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

in the terminal it&#39;s working but while running on the eclipse IDE it&#39;s giving me a error.

Don&#39;t know how to overcome..

SyntaxError of Non-ASCII character

I realise that it&#39;s not elegant or desired, but is it allowed (in well-formed XML) for an attribute value in an XML element to span multiple lines?

e.g.

    &lt;some-xml-element value=&quot;this value goes over....
    multiple lines!&quot; /&gt;

Yeah I realise there&#39;s better ways of writing that. I would personally write it like:

    &lt;some-xml-element&gt;
    &lt;value&gt;this value goes over...
    multiple lines!&lt;/value&gt;
    &lt;/some-xml-element&gt;

or:

    &lt;some-xml-element value=&quot;this value goes over....&amp;#13;&amp;#10;&quot; /&gt;

But we have our own XML parser and I&#39;d like to know whether the first example is allowed in well-formed XML.

Are line breaks in XML attribute values allowed?

I have Google checkout sandbox generated HTML code which works fine in HTML page. When I put the same code in XHTML page, it throws the below exception:

jQuery XML error &#39; No &#39;Access-Control-Allow-Origin&#39; header is present on the requested resource.&#39;

I&#39;m trying to parse some XML inside a WiX installer. The XML would be an object of all my errors returned from a web server. I&#39;m getting the error in the question title with this code:

    XmlDocument xml = new XmlDocument();
    try
    {
    	xml.LoadXml(myString);
    }
    catch (Exception ex)
    {
    	System.IO.File.WriteAllText(@&quot;C:\text.txt&quot;, myString + &quot;\r\n\r\n&quot; + ex.Message);
    	throw ex;
    }

`myString` is this (as seen in the output of `text.txt`)

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;Errors&gt;&lt;/Errors&gt;

`text.txt` comes out looking like this:

Streaming xml-parsers like SAX and StAX are faster and more memory efficient than parsers building a tree-structure like DOM-parsers. SAX is a push parser, meaning that it&#39;s an instance of the observer pattern (also called listener pattern). SAX was there first, but then came StAX - a pull parser, meaning that it basically works like an iterator.

You can find reasons why to prefer StAX over SAX everywhere, but it usually boils down to: &quot;it&#39;s easier to use&quot;.

In the Java tutorial on JAXP StAX is vaguely presented as the middle between DOM and SAX: &quot;it&#39;s easier than SAX and more efficient than DOM&quot;. However, I never found any clues that StAX would be slower or less memory efficient than SAX.

All this made me wonder: *are there any reasons to choose SAX instead of StAX?*

When should I choose SAX over StAX?

I searched for a while on this topic and found some results too, which I am mentioning at the end of post. Can someone help me precisely answer these three questions for the cases listed below them?

1. For which use-cases using XmlSluper makes more sense than XmlParser and vice-versa (from point of view ease of use of API/Syntax)?

2. Which one is more memory efficient? (looks like Slurper)

3. which one processes the xml faster?

Case a. when I have to read almost all nodes in the xml?

Case b. when I have to read just few nodes (like using gpath expression)?

Case c. when I have to update/transform the xml?


provided the xml document is not trivial one (with level of depths and size of the xml).


**Resources** : 

http://www.tutkiun.com/2009/10/xmlparser-and-xmlslurper.html states :

&gt; Difference between XMLParser and XMLSlurper:
&gt; 
&gt; There are similarities between XMLParser and XMLSlurper when used for
&gt; simple reading but when we use them for advanced reading and when
&gt; processing XML documents in other formats there are differences
&gt; between two.
&gt; 
&gt; XMLParser stores intermediate results after parsing documents. But on
&gt; the other hand, 
&gt; 
&gt; XMLSlurper does not stores internal results after processing XML
&gt; documents.
&gt; 
&gt; The real, fundamental differences become apparent when processing the
&gt; parsed information. That is when processing with direct in-place data
&gt; manipulation and processing in a streaming scenario.

But every day I recieve an XML report from Google.

I don&#39;t understand what the problem is?

The report is:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot; ?&gt;
    &lt;feedback&gt;
      &lt;report_metadata&gt;
        &lt;org_name&gt;google.com&lt;/org_name&gt;
        &lt;email&gt;noreply-dmarc-support@google.com&lt;/email&gt;
        &lt;extra_contact_info&gt;http://support.google.com/a/bin/answer.py?answer=2466580&lt;/extra_contact_info&gt;
        &lt;report_id&gt;7241837801886321635&lt;/report_id&gt;
        &lt;date_range&gt;
          &lt;begin&gt;1431388800&lt;/begin&gt;
          &lt;end&gt;1431475199&lt;/end&gt;
        &lt;/date_range&gt;
      &lt;/report_metadata&gt;
      &lt;policy_published&gt;
        &lt;domain&gt;rigweb.ru&lt;/domain&gt;
        &lt;adkim&gt;r&lt;/adkim&gt;
        &lt;aspf&gt;r&lt;/aspf&gt;
        &lt;p&gt;none&lt;/p&gt;
        &lt;sp&gt;none&lt;/sp&gt;
        &lt;pct&gt;100&lt;/pct&gt;
      &lt;/policy_published&gt;
      &lt;record&gt;
        &lt;row&gt;
          &lt;source_ip&gt;144.76.154.188&lt;/source_ip&gt;
          &lt;count&gt;2&lt;/count&gt;
          &lt;policy_evaluated&gt;
            &lt;disposition&gt;none&lt;/disposition&gt;
            &lt;dkim&gt;pass&lt;/dkim&gt;
            &lt;spf&gt;pass&lt;/spf&gt;
          &lt;/policy_evaluated&gt;
        &lt;/row&gt;
        &lt;identifiers&gt;
          &lt;header_from&gt;site.ru&lt;/header_from&gt;
        &lt;/identifiers&gt;
        &lt;auth_results&gt;
          &lt;dkim&gt;
            &lt;domain&gt;rigweb.ru&lt;/domain&gt;
            &lt;result&gt;pass&lt;/result&gt;
          &lt;/dkim&gt;
          &lt;spf&gt;
            &lt;domain&gt;site.ru&lt;/domain&gt;
            &lt;result&gt;pass&lt;/result&gt;
          &lt;/spf&gt;
        &lt;/auth_results&gt;
      &lt;/record&gt;
    &lt;/feedback&gt;

My DMARC Policy:

    v=DMARC1; sp=none; aspf=r; p=none; rua=mailto: support@site.ru

How can I solve the problem?


Why do I receive a DMARC report everyday?

I have a string defined in an android application:

`&lt;string name=&quot;search_occurs&quot;&gt;&#39;{string}&#39; occurs {times}&lt;/string&gt;`

This gives the error: Apostrophe not preceded by \ (in &#39;{string}&#39; occurs {times})

I&#39;ve tried a number of things to fix this:

    &lt;string name=&quot;search_occurs&quot;&gt;\&#39;{string}\&#39; occurs {times}&lt;/string&gt;
    &lt;string name=&quot;search_occurs&quot;&gt;&amp;apos;{string}&amp;apos; occurs {times}&lt;/string&gt;
    &lt;string name=&quot;search_occurs&quot;&gt;&lt;![CDATA[&#39;{string}&#39; occurs {times}]]&gt;&lt;/string&gt;
    &lt;string name=&quot;search_occurs&quot;&gt;&lt;![CDATA[\&#39;{string}\&#39; occurs {times}]]&gt;&lt;/string&gt;

I&#39;m not able to get rid of the error.  What am I missing?

I want to parse my XML document. So I have stored my XML document as below

    class XMLdocs(db.Expando):  
       id = db.IntegerProperty()   	
       name=db.StringProperty()  
       content=db.BlobProperty()  

Now my below is my code

    parser = make_parser()     
    curHandler = BasketBallHandler()  
    parser.setContentHandler(curHandler)  
    for q in XMLdocs.all():  
            parser.parse(StringIO.StringIO(q.content))

I am getting below error

I have a file containing the following lines:

      &lt;parameter name=&quot;PortMappingEnabled&quot; access=&quot;readWrite&quot; type=&quot;xsd:boolean&quot;&gt;&lt;/parameter&gt;
      &lt;parameter name=&quot;PortMappingLeaseDuration&quot; access=&quot;readWrite&quot; activeNotify=&quot;canDeny&quot; type=&quot;xsd:unsignedInt&quot;&gt;&lt;/parameter&gt;
      &lt;parameter name=&quot;RemoteHost&quot; access=&quot;readWrite&quot;&gt;&lt;/parameter&gt;
      &lt;parameter name=&quot;ExternalPort&quot; access=&quot;readWrite&quot; type=&quot;xsd:unsignedInt&quot;&gt;&lt;/parameter&gt;
      &lt;parameter name=&quot;ExternalPortEndRange&quot; access=&quot;readWrite&quot; type=&quot;xsd:unsignedInt&quot;&gt;&lt;/parameter&gt;
      &lt;parameter name=&quot;InternalPort&quot; access=&quot;readWrite&quot; type=&quot;xsd:unsignedInt&quot;&gt;&lt;/parameter&gt;
      &lt;parameter name=&quot;PortMappingProtocol&quot; access=&quot;readWrite&quot;&gt;&lt;/parameter&gt;
      &lt;parameter name=&quot;InternalClient&quot; access=&quot;readWrite&quot;&gt;&lt;/parameter&gt;
      &lt;parameter name=&quot;PortMappingDescription&quot; access=&quot;readWrite&quot;&gt;&lt;/parameter&gt;



I want to execute command on this file to extract only the parameter names as displayed in the following output:

    $sedcommand file.txt
    PortMappingEnabled
    PortMappingLeaseDuration
    RemoteHost
    ExternalPort
    ExternalPortEndRange
    InternalPort
    PortMappingProtocol
    InternalClient
    PortMappingDescription

What could be this command?

How to use sed to extract substring

I have XML documents that I need to parse and/or I need to build XML documents and write them to text (either files or memory). Since the C++ standard library does not have a library for this, what should I use?

**Note:** This is intended to be a definitive, C++-FAQ-style question for this. So yes, it is a duplicate of others. I did not simply appropriate those other questions because they tended to ask for something slightly more specific. This question is more generic.


What XML parser should I use in C++?

How do I go about writing a Parser (Recursive Descent?) in C#? For now I just want a simple parser that parses arithmetic expressions (and reads variables?). Though later I intend to write an xml and html parser (for learning purposes). I am doing this because of the wide range of stuff in which parsers are useful: Web development, Programming Language Interpreters, Inhouse Tools, Gaming Engines, Map and Tile Editors, etc. So what is the basic theory of writing parsers and how do I implement one in C#? Is C# the right language for parsers (I once wrote a simple arithmetic parser in C++ and it was efficient.  Will JIT compilation prove equally good?). Any helpful resources and articles. And best of all, code examples (or links to code examples). 

Note: Out of curiosity, has anyone answering this question ever implemented a parser in C#?

How to write a Parser in C#?

I am getting very strange &quot;Premature end of file.&quot; exception for last few days on one of our servers. The *same* configuration XML works fine on another server. We are using Tomcat 5.0.28 on both these servers. This code has been working for ages (7+ years), only after recent server crash, we faced this problem on one of the servers. There is no change in XML as well as Java parsing code. :(

The only difference I can see is in Java versions - 

**Problem Server**
java version &quot;1.6.0_16&quot;
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)

**Working Server**
java version &quot;1.6.0_07&quot;
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) 64-Bit Server VM (build 10.0-b23, mixed mode)

Here is the Java code that has been working for several years -

    private void readSource(final InputSource in ) {
    	try {
    		DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    		DocumentBuilder db = dbf.newDocumentBuilder();
    		Document doc = db.parse(in);
    		Element elt = doc.getDocumentElement();
    	
    		this.readElement( elt );
    	} catch ( Exception ex ) {
    		ex.printStackTrace();
    		throw new ConfigurationException( &quot;Unable to parse configuration information&quot;, ex );
    	}
    }

And here is the exception. 

    [Fatal Error] :-1:-1: Premature end of file.
    org.xml.sax.SAXParseException: Premature end of file.
            at org.apache.xerces.parsers.DOMParser.parse(Unknown Source)
            at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(Unknown Source)
            at com.circus.core.Configuration.readSource(Configuration.java:706)

I have already tried validating XML and found no errors there. Any idea where else can I look for possible problem? 

Any pointers would be highly appreciated!

TIA,
- Manish
