Should be something similar to:

&lt;pre&gt;
//a[text()=&#39;text_i_want_to_find&#39;]/@href
&lt;/pre&gt;

Too late for you, but for anyone else with the same question...

```xpath
//a[contains(text(), &#39;programming&#39;)]/@href
```

Of course, &#39;programming&#39; can be any text fragment.



```xpath
//a[text()=&#39;programming quesions site&#39;]/@href 
```

which basically identifies an anchor node `&lt;a&gt;` that has the text you want, and extracts the `href` attribute.

Think of the phrase in the square brackets as a WHERE clause in SQL.

So this query says, &quot;select the &quot;href&quot; attribute (@) of an &quot;a&quot; tag that appears anywhere (//), but only where (the bracketed phrase) the textual contents of the &quot;a&quot; tag is equal to &#39;programming questions site&#39;&quot;.



For case insensitive contains, use the following:

```xpath
//a[contains(translate(text(),&#39;PROGRAMMING&#39;,&#39;programming&#39;), &#39;programming&#39;)]/@href
```

translate converts capital letters in PROGRAMMING to lower case programming.

if you are using html agility pack use getattributeValue:

    $doc2.DocumentNode.SelectNodes(&quot;//div[@class=&#39;className&#39;]/div[@class=&#39;InternalClass&#39;]/a[@class=&#39;InternalClass&#39;]&quot;).GetAttributeValue(&quot;href&quot;,&quot;&quot;)

I&#39;m wondering how to ignore a parent style and use the default style (none). I&#39;ll show my specific case as an example but I&#39;m pretty sure this is a general question.

    &lt;style&gt;
    #elementId select {
        height:1em;
    }
    &lt;/style&gt;

    &lt;div id=&quot;elementId&quot;&gt;
        &lt;select name=&quot;funTimes&quot; style=&quot;&quot; size=&quot;5&quot;&gt;
            &lt;option value=&quot;test1&quot;&gt;fish&lt;/option&gt;
            &lt;option value=&quot;test2&quot;&gt;eat&lt;/option&gt;
            &lt;option value=&quot;test3&quot;&gt;cows&lt;/option&gt;
        &lt;/select&gt;
    &lt;/div&gt;

Ways I do not want to solve this problem:

 - I cannot edit the stylesheet where the &quot;#elementId select&quot; is set, my module won&#39;t have access that. 
 - Preferably not override the height style using the style attribute. 

For example using firebug i can turn off the parent style and all is well, this is the effect I am going for. 

**Once a style is set, can it be disabled or must it be overridden?**

What is the difference between `XPath`, `XQuery` and `XPointer`? As far as I know, `XQuery` is an extended version of `XPath`. I have some basic knowledge of `XPath`. Is there any feature available in `XPath` which is not in `XQuery`? Yesterday, I heard a new word, `XPointer`. I am confused. Which language is used for which purpose?

How can I read an XML attribute using C#&#39;s XmlDocument?

I have an XML file which looks somewhat like this:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot; ?&gt;
    &lt;MyConfiguration xmlns=&quot;http://tempuri.org/myOwnSchema.xsd&quot; SuperNumber=&quot;1&quot; SuperString=&quot;whipcream&quot;&gt;
        &lt;Other stuff /&gt;
    &lt;/MyConfiguration&gt; 


How would I read the XML attributes SuperNumber and SuperString?

Currently I&#39;m using XmlDocument, and I get the values in between using XmlDocument&#39;s `GetElementsByTagName()` and that works really well. I just can&#39;t figure out how to get the attributes?


Read XML Attribute using XmlDocument

I have a WCF service that needs to return a string of XML.  But it seems like the writer only wants to build up a file, not a string.  I tried:

    string nextXMLstring = &quot;&quot;;
    using (XmlWriter writer = XmlWriter.Create(nextXMLstring))

This generates an error saying nextXMLstring doesnt have a file path.  It wants something like:

    using (XmlWriter writer = XmlWriter.Create(&quot;nextXMLstring.xml&quot;))

How can I build up my XML and then return it as a string??

Thanks!!

Is there any way to have an XDocument print the xml version when using the ToString method? Have it output something like this:

&lt;pre&gt;&lt;code&gt;&amp;lt;?xml version=&quot;1.0&quot;?&amp;gt;
&amp;lt;!DOCTYPE ELMResponse [
]&amp;gt;
&amp;lt;Response&amp;gt;
&amp;lt;Error&amp;gt; ...&lt;/code&gt;&lt;/pre&gt;

I have the following:

&lt;pre&gt;&lt;code&gt;var xdoc = new XDocument(new XDocumentType(&quot;Response&quot;, null, null, &quot;\n&quot;), ...&lt;/code&gt;&lt;/pre&gt;

which will print this which is fine, but it is missing the &quot;&amp;lt;?xml version&quot; as stated above.

&lt;pre&gt;&lt;code&gt;&amp;lt;!DOCTYPE ELMResponse [
]&amp;gt;
&amp;lt;Response&amp;gt;
&amp;lt;Error&amp;gt; ...&lt;/code&gt;&lt;/pre&gt;

I know that you can do this by outputting it manually my self. Just wanted to know if it was possible by using XDocument.

I was playing around with some ideas using raw html and JQuery.  One thing I did was to create an table element with a set of rows.

    &lt;table id=&quot;MyTable&quot; &gt;
        &lt;tr&gt;
            &lt;td&gt;Title&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;td&gt;1&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;td&gt;2&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;td&gt;3&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;td&gt;4&lt;/td&gt;
        &lt;/tr&gt;
    &lt;/table&gt;

But when I viewed the code in FireFox+Firebug, IE8 Developer Toolbar, or the Google Chrome JavaScript Debugger...all of them showed there to be a **tbody** element surrounding all of the **tr** nodes.

I&#39;m not against this happening...but is this standard behavior?

Why do browsers insert tbody element into table elements?

Does anyone know of a good resource to explain good naming conventions for HTML ID and classes and whether to prefix with IDs with an element type i.e. btn or button or similar?

Should classes be plural or singular?  I get that IDs should be singular due to them being unique, but what about classes?

IDs and classes should use nouns, right?

I am using pages that inject other pages in the existing pages, kind of like partial pages ... hence... I was wondering if anybody as prefixed a name in front of IDs and/or classes .. kind of like a namespace or similar?

Any comments or insights really appreciated.

HTML naming conventions for ID, class and to include element type prefix?

HTML being the most widely used language (at least as a markup language) has not gotten its due credit. &lt;br/&gt;
Considering that it has been around for so many years, things like the FORM / INPUT controls have still remained same with no new controls added.

So at least from the existing features, do you know any features that are **not well known** but very useful.

Of course, this question is along the lines of:

[Hidden Features of JavaScript][1]&lt;br /&gt;
[Hidden Features of CSS][2]&lt;br/&gt;
[Hidden Features of C#][3]&lt;br /&gt;
[Hidden Features of VB.NET][4]&lt;br /&gt;
[Hidden Features of Java][5]&lt;br /&gt;
[Hidden Features of classic ASP][6]&lt;br /&gt;
[Hidden Features of ASP.NET][7]&lt;br /&gt;
[Hidden Features of Python][8]&lt;br /&gt;
[Hidden Features of TextPad][9]&lt;br/&gt;
[Hidden Features of Eclipse][10]

Do not mention features of HTML 5.0, since it is in [working draft][11]&lt;br/&gt;

**Please specify one feature per answer**.&lt;br/&gt;

Hidden features of HTML

Recently I have been reading more and more about people using custom attributes in their HTML tags, mainly for the purpose of embedding some extra bits of data for use in javascript code.

I was hoping to gather some feedback on whether or not using custom attributes is a good practice, and also what some alternatives are.

It seems like it can really simplify *both* server side and client side code, but it also isn&#39;t W3C compliant.  

Should we be making use of custom HTML attributes in our web apps?   Why or why not?

For those who think custom attributes are a good thing:  what are some things to keep in mind when using them?

For those who think custom attributes are bad thing: what alternatives do you use to accomplish something similar?

**Update:**  I&#39;m mostly interested in the *reasoning* behind the various methods, as well as points as to why one method is better than another.  I think we can all come up with 4-5 different ways to accomplish the same thing.  (hidden elements, inline scripts, extra classes, parsing info from ids, etc). 

**Update 2:**  It seems that the HTML 5 `data-` attribute feature has a lot of support here (and I tend to agree, it looks like a solid option).  So far I haven&#39;t seen much in the way of rebuttals for this suggestion.   Are there any issues/pitfalls to worry about using this approach?   Or is it simply a &#39;harmless&#39; invalidation of the current W3C specs?

Custom attributes - Yea or nay?

I know that is the reason some people don&#39;t approve of them, but does it really matter?  I think that the power that they provide, in interacting with JavaScript and storing and sending information from and to the server, outweighs the validation concern. Am I missing something?  What are the ramifications of &quot;invalid&quot; HTML?  And wouldn&#39;t a custom DTD resolve them anyway?

So what if custom HTML attributes aren&#39;t valid XHTML?

The XPath `bookstore/book[1]` selects the first book node under `bookstore`.

How can I select the first node that matches a more complicated condition, e.g. the first node that matches `/bookstore/book[@location=&#39;US&#39;]`

In XSLT, what is the difference between the &quot;current node&quot; and the &quot;context node&quot;? You can find both terms used here: http://www.w3.org/TR/xslt.

When would you use one or the other? How do you refer to each?

Current node vs. Context node in XSLT/XPath?

I&#39;m trying to learn XPath. I looked at the other `contains()` examples around here, but nothing that uses an *AND* operator. I can&#39;t get this to work:

    //ul[@class=&#39;featureList&#39; and contains(li, &#39;Model&#39;)]

On:

    ...
    &lt;ul class=&quot;featureList&quot;&gt;
        
    &lt;li&gt;&lt;b&gt;Type:&lt;/b&gt; Clip Fan&lt;/li&gt;&lt;li&gt;&lt;b&gt;Feature:&lt;/b&gt; Air Moved: 65 ft.
        Amps: 1.1
        Clip: Grips any surface up to 1.63&quot;
        Plug: 3 prong grounded plug on heavy duty model
        Usage: Garage, Workshop, Dorm, Work-out room, Deck, Office &amp; more.&lt;/li&gt;&lt;li&gt;&lt;b&gt;Speed Setting:&lt;/b&gt; 2 speeds&lt;/li&gt;&lt;li&gt;&lt;b&gt;Color:&lt;/b&gt; Black&lt;/li&gt;&lt;li&gt;&lt;b&gt;Power Consumption:&lt;/b&gt; 62 W&lt;/li&gt;&lt;li&gt;&lt;b&gt;Height:&lt;/b&gt; 14.5&quot;&lt;/li&gt;&lt;li&gt;&lt;b&gt;Width:&lt;/b&gt; Grill Diameter: 9.5&quot;&lt;/li&gt;&lt;li&gt;&lt;b&gt;Length:&lt;/b&gt; 11.5&quot;&lt;/li&gt;
        
    &lt;li&gt;&lt;b&gt;Model #: &lt;/b&gt;CR1-0081-06&lt;/li&gt;
    &lt;li&gt;&lt;b&gt;Item #: &lt;/b&gt;N82E16896817007&lt;/li&gt;
    &lt;li&gt;&lt;b&gt;Return Policy: &lt;/b&gt;&lt;/li&gt;
    &lt;/ul&gt;
    ...

How to use XPath contains() here?

I am new to using XPath and this may be a basic question. Kindly bear with me and help me in resolving the issue. I have an XML file like this:

    &lt;RootNode&gt;
      &lt;FirstChild&gt;
        &lt;Element attribute1=&quot;abc&quot; attribute2=&quot;xyz&quot;&gt;Data&lt;/Element&gt;
      &lt;FirstChild&gt;
    &lt;/RootNode&gt;

I can validate the presence of an `&lt;Element&gt;` tag with:

&lt;pre&gt;//Element[@attribute1=&quot;abc&quot; and @attribute2=&quot;xyz&quot;]&lt;/pre&gt;

Now I also want to check the value of the tag for string `&quot;Data&quot;`. For achieving this I was told to use:
 
&lt;pre&gt;//Element[@attribute1=&quot;abc&quot; and @attribute2=&quot;xyz&quot; and Data]&lt;/pre&gt;

When I use the later expression I get the following error:

&gt;Assertion failure message: No Nodes Matched `//Element[@attribute1=&quot;abc&quot; and @attribute2=&quot;xyz&quot; and Data]`

Kindly provide me with your advice whether the XPath expression I have used is valid. If not what will be the valid XPath expression?
