    select=&quot;//*[contains(@address,&#39;Downing&#39;)]&quot;

I want to make a preference for hiding the Dock icon and showing an `NSStatusItem`.
I can create the StatusItem but I don&#39;t know how to remove the icon from Dock. :-/

Any ideas?

I was thinking of implementing real time chat using a PHP backend, but I ran across this comment on a site discussing comet:

&gt; My understanding is that PHP is a
&gt; terrible language for Comet, because
&gt; Comet requires you to keep a
&gt; persistent connection open to each
&gt; browser client. Using mod_php this
&gt; means tying up an Apache child
&gt; full-time for each client which
&gt; doesn’t scale at all. The people I
&gt; know doing Comet stuff are mostly
&gt; using Twisted Python which is designed
&gt; to handle hundreds or thousands of
&gt; simultaneous connections.

Is this true? Or is it something that can be configured around?

Is there an xpath way to find a node that has a given attribute whose value contains a given string?

For example I have an xml document and want to find a node where the `address` attribute contains the string `Downing`, so that I could find the following node:

    &lt;person name=&quot;blair&quot; address=&quot;10 Downing St. London&quot;/&gt;

How do I read and parse an XML file in C#?

The ElementTree.parse reads from a file, how can I use this if I already have the XML data in a string?

Maybe I am missing something here, but there must be a way to use the ElementTree without writing out the string to a file and reading it again.

I have a **variable string** that contains well-formed and valid XML. I need to use JavaScript code to parse this feed.

How can I accomplish this using (browser-compatible) JavaScript code?


XML parsing of a variable string in JavaScript

Pretty simple question - I have an attribute that I would like to have double quotes in.  How do I escape them?  I&#39;ve tried

 - \&quot;
 - &quot;&quot;
 - \\\&quot;

And I&#39;ve made the @xml variable both xml type and varchar(max) for all of them.

     declare @xml xml --(or varchar(max) tried both)
     
     set @xml = &#39;&lt;transaction&gt;&lt;item value=&quot;hi &quot;mom&quot; lol&quot; 
     	ItemId=&quot;106&quot;  ItemType=&quot;2&quot;  instanceId=&quot;215923801&quot;  dataSetId=&quot;1&quot; /&gt;&lt;/transaction&gt;&#39;
     
     declare @xh int
     exec sp_xml_preparedocument @xh OUTPUT, @xml
     
     insert into @commits --I declare the table, just removed it for brevity
     select
     	x.*
     from openxml(@xh,&#39;/transaction/item&#39;)
      WITH (
     	dataItemId int,
         dataItemType int,
     	instanceId int,
     	dataSetId int,
     	value varchar(max)

I have a [GWT][1] application for which I&#39;m trying to write some tests using [Selenium][2].

I&#39;m using XPath to identify the elements on the page for the tests.  Using `id` won&#39;t work as the `id` values are auto-generated by GWT and can change.  Things started going well when I realised I could find buttons by their labels as follows:

    //button[.=&#39;OK&#39;]

However, when I started running multiple tests I started having problems.  I realised that the issue was all the different &quot;pages&quot; of the GWT app once generated by the Javascript remain in the HTML in hidden `&lt;div&gt;` elements.  This meant my Selenium tests were sometimes clicking hidden buttons instead of the button visible in the current view.

Examining the HTML with [Firebug][3], it seems that GWT hides the `&lt;div&gt;` elements by adding `display: none` to their `style` attribute.  This means I can find all the hidden OK buttons as follows:

    //div[contains(@style,&#39;display: none&#39;)]//button[.=&#39;OK&#39;]

This will find all the hidden OK buttons, i.e the buttons which have an ancestor `&lt;div&gt;` which is hidden by having `display: none` in the `style`.

My question is: how do I use XPath to find only the visible OK buttons?  How do I find the buttons which have no ancestor `&lt;div&gt;` elements with `display: none` in the `style`?

How do I select only visible elements using XPath?

I know there are some online regex evaluators.. very useful, matching in real time. They are like web applications of RegexBuddy.

I was wondering if there is a similar thing for xPath selectors? I am just learning them and it would be valuable to me.

Is there an online tester that allows you to input XML and then an xPath selector and match (live would be better, but I doubt someone has written a JavaScript interpreter?) them?

Thanks

Given this simplified data format:

        &lt;c&gt;not this one&lt;/c&gt;
        &lt;d&gt;nor this one&lt;/d&gt;
        &lt;e&gt;definitely not this one&lt;/e&gt;
    &lt;/a&gt;

How would you select all the `C`s, `D`s and `E`s that are children of `B` elements?

Basically, something like:

    a/b/(c|d|e)

In my own situation, instead of just `a/b/`, the query leading up to selecting those `C`, `D`, `E` nodes is actually quite complex so I&#39;d like to avoid doing this:

    a/b/c|a/b/d|a/b/e

Is this possible?

Using a XPath query how do you find if a node (tag) exists at all?

I need to determine if a value exists in an array.

I am using the following function:

    Array.prototype.contains = function(obj) {
        var i = this.length;
        while (i--) {
            if (this[i] == obj) {
                return true;
            }
        }
        return false;
    }

The above function always returns false.

The array values and the function call is as below:

    arrValues = [&quot;Sam&quot;,&quot;Great&quot;, &quot;Sample&quot;, &quot;High&quot;]
    alert(arrValues.contains(&quot;Sam&quot;));

&lt;p&gt;I know that the compiler sometimes provides a default copy constructor if you don&#39;t implement yourself. I am confused about what exactly this constructor does. If I have a class that contains other objects, none of which have a declared copy constructor, what will the behavior be? For example, a class like this:&lt;/p&gt;
    class Foo {
      Bar bar;
    };

    class Bar {
      int i;
      Baz baz;
    };

    class Baz {
      int j;
    };
&lt;p&gt;Now if I do this:&lt;/p&gt;
    Foo f1;
    Foo f2(f1);
&lt;p&gt;What will the default copy constructor do? Will the compiler-generated copy constructor in &lt;code&gt;Foo&lt;/code&gt; call the compiler-generated constructor in &lt;code&gt;Bar&lt;/code&gt; to copy over &lt;code&gt;bar&lt;/code&gt;, which will then call the compiler-generated copy constructor in &lt;code&gt;Baz&lt;/code&gt;?

I&#39;m trying to use &quot;contains&quot; case insensitively. I tried using the solution at the following stackoverflow question, but it didn&#39;t work:

https://stackoverflow.com/questions/187537/is-there-a-case-insensitive-jquery-contains-selector/187557#187557

*For convenience, the solution is copied here:*

    jQuery.extend(
            jQuery.expr[&#39;:&#39;], { 
                    Contains : &quot;jQuery(a).text().toUpperCase().indexOf(m[3].toUpperCase())&gt;=0&quot; 
    });


*Here is the error:*

    Error: q is not a function
    Source File: /js/jquery-1.4.js?ver=1.4
    Line: 81

*Here&#39;s where I&#39;m using it:*

      $(&#39;input.preset&#39;).keyup(function() {
        $(this).next().find(&quot;li&quot;).removeClass(&quot;bold&quot;);
        var theMatch = $(this).val();
        if (theMatch.length &gt; 1){
          theMatch = &quot;li:Contains(&#39;&quot; + theMatch + &quot;&#39;)&quot;;
          $(this).next().find(theMatch).addClass(&quot;bold&quot;);
        }
      });

My use of the original case sensitive &quot;contains&quot; in the same scenario works without any errors. Does anyone have any ideas? I&#39;d appreciate it.


How do I make jQuery Contains case insensitive, including jQuery 1.8+?

Is there a method for checking if a table contains a value ? I have my own (naive) function, but I was wondering if something &quot;official&quot; exists for that ? Or something more efficient...

    function table.contains(table, element)
      for _, value in pairs(table) do
        if value == element then
          return true
        end
      end
      return false
    end

By the way, the main reason I&#39;m using this functions is to use tables as sets, ie with no duplicate elements. Is there something else I could use ?
