you can use this:

    /root/a/b[position()=$variable]


position() is 1 based

http://saxon.sourceforge.net/saxon6.5.3/expressions.html


The following should work:

    /root/a/b[2]

And if it doesn&#39;t, try:

    /root/a/b[position()=2]

I have a JLabel which has a lot of text on it. Is there a way to make the JLabel have a max width so that it will wrap the text to make it not exceed this width?

Thanks

WHat is a good way to format a python decimal like this way? 

1.00 --&gt; &#39;1&#39;  
1.20 --&gt; &#39;1.2&#39;  
1.23 --&gt; &#39;1.23&#39;  
1.234 --&gt; &#39;1.23&#39;  
1.2345 --&gt; &#39;1.23&#39;

My sample input XML is:

    &lt;root&gt;
     &lt;a&gt;
       &lt;b&gt;item&lt;/b&gt;
       &lt;b&gt;item1&lt;/b&gt;
       &lt;b&gt;item2&lt;/b&gt;
       &lt;b&gt;item3&lt;/b&gt;
       &lt;b&gt;item4&lt;/b&gt;
     &lt;/a&gt;
    &lt;/root&gt;


I am suppose to select a node `b` whose position is the value of a variable.

How can I use the value of a variable to test the position of a node?

I&#39;m trying to read the following Xml document as fast as I can and let additional classes manage the reading of each sub block.

   

    &lt;ApplicationPool&gt;
        &lt;Accounts&gt;
            &lt;Account&gt;
                &lt;NameOfKin&gt;&lt;/NameOfKin&gt;
                &lt;StatementsAvailable&gt;
                    &lt;Statement&gt;&lt;/Statement&gt;
                &lt;/StatementsAvailable&gt;
            &lt;/Account&gt;
        &lt;/Accounts&gt;
    &lt;/ApplicationPool&gt;

However, I&#39;m trying to use the XmlReader object to read each Account and subsequently the &quot;StatementsAvailable&quot;. Do you suggest using XmlReader.Read and check each element and handle it?

I&#39;ve thought of seperating my classes to handle each node properly. So theres an AccountBase class that accepts a XmlReader instance that reads the NameOfKin and several other properties about the account. Then I was wanting to interate through the Statements and let another class fill itself out about the Statement (and subsequently add it to an IList).

Thus far I have the &quot;per class&quot; part done by doing XmlReader.ReadElementString() but I can&#39;t workout how to tell the pointer to move to the StatementsAvailable element and let me iterate through them and let another class read each of those proeprties.

Sounds easy!

Reading Xml with XmlReader in C#

I don&#39;t really understand the difference between the XPath functions [`name`](http://www.w3.org/TR/xpath/#function-name) and [`local-name`](http://www.w3.org/TR/xpath/#function-local-name).

Could you give an example of a situation where they would differ?

Edit
---

Given this example:

    &lt;?xml version=&quot;1.0&quot; ?&gt;
    &lt;html xmlns=&quot;http://www.w3.org/1999/xhtml&quot; xml:lang=&quot;en&quot; lang=&quot;en&quot;&gt;
      &lt;head&gt;&lt;/head&gt;
    &lt;/html&gt;

I get the same result with these two queries: `//*[local-name()=&quot;head&quot;]` and `//*[name()=&quot;head&quot;]`. Why is that?

What is the difference between name() and local-name()?

I have made an XML Schema - all the code basically - and was wondering if there is a way that the code can generate something like this:

How to visualize an XML schema programatically?

I&#39;m getting the error:

`parser error : Input is not proper UTF-8, indicate encoding ! Bytes: 0xED 0x6E 0x2C 0x20`

When trying to process an XML response using `simplexml_load_string` from a 3rd party source. The raw XML response does declare the content type:

`&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt; `

Yet it seems that the XML is not really UTF-8. The langauge of the XML content is Spanish and contain words like `Dubl&#237;n` in the XML.

I&#39;m unable to get the 3rd party to sort out their XML.

How can I pre-process the XML and fix the encoding incompatibilities?

Is there a way to detect the correct encoding for a XML file?

We are using a *PropertyPlaceholderConfigurer* to use java properties in our Spring configuration ([details here][1])

eg:

    &lt;foo name=&quot;port&quot;&gt;
      &lt;value&gt;${my.server.port}&lt;/value&gt;
    &lt;/foo&gt;

We would like to add an additional property, but have a distributed system where existing instances could all use a default value.  Is there a way to avoid updating all of our properties files, by indicating a default value in the Spring config for when there isn&#39;t an overriding property value defined?

I&#39;m trying to do a xpath lookup on nodes returned by xpath lookup, but it doesn&#39;t seem to work as I expected.XPaths executed on the child nodes of a document seem to be executd against hthe root node of the document (in the example, the inventory tag.), instead of the root of the provided node.

Am I missing something here? I&#39;m new to XPath.

Also, please don&#39;t answer &quot;just do //book[author=&#39;Neal Stephenson&#39;/title&quot;. I have a legitimate use case, and this is a simplified example.



Code snippet

    DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
    domFactory.setNamespaceAware(true);
    DocumentBuilder builder = domFactory.newDocumentBuilder();
    Document doc = builder.parse(&quot;src/main/java/books.xml&quot;);

    XPathFactory factory = XPathFactory.newInstance();
    XPath xpath = factory.newXPath();

    Node book = (Node) xpath.evaluate(&quot;//book[author=&#39;Neal Stephenson&#39;]&quot;, doc, XPathConstants.NODE);
    Node title = (Node) xpath.evaluate(&quot;/title&quot;, book, XPathConstants.NODE); // I get null here.
    Node inventory = (Node) xpath.evaluate(&quot;/inventory&quot;, book, XPathConstants.NODE); // this returns a node.


book.xml

	&lt;inventory&gt;
	&lt;book year=&quot;2000&quot;&gt;
		&lt;title&gt;Snow Crash&lt;/title&gt;
		&lt;author&gt;Neal Stephenson&lt;/author&gt;
		&lt;publisher&gt;Spectra&lt;/publisher&gt;
		&lt;isbn&gt;0553380958&lt;/isbn&gt;
		&lt;price&gt;14.95&lt;/price&gt;
	&lt;/book&gt;

Running XPath on child node

How to ignore first element in xpath

Is there anyway to return an XPath string of a DOM element in Javascript?

Javascript get XPath of a node

I want to read XML data using XPath in Java, so for the information I have gathered I am not able to parse XML according to my requirement.

here is what I want to do:

**Get XML file from online via its URL, then use XPath to parse it, I want to create two methods in it. One is in which I enter a specific node attribute id, and I get all the child nodes as result, and second is suppose I just want to get a specific child node value only**

In above example I want to read all the elements if I search via @name and also one function in which I just want the url from @name &#39;Javascript&#39; only return one node element.
