New pseudo classes and matchers can be plugged. It works on HTML and XML documents (if a content node is passed in).</p>
-
-<p>
-DomQuery supports most of the <a href="http://www.w3.org/TR/2005/WD-css3-selectors-20051215/#selectors">CSS3 selectors spec</a>, along with some custom selectors and basic XPath.</p>
-
-
-
-
-<p>
-All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example "div.foo:nth-child(odd)[@foo=bar].bar:first" would be a perfectly valid selector. Node filters are processed in the order in which they appear, which allows you to optimize your queries for your document structure.
-</p>
-
-
-<h4>Element Selectors:</h4>
-
-
-<ul class="list">
- <li> <b>*</b> any element</li>
- <li> <b>E</b> an element with the tag E</li>
- <li> <b>E F</b> All descendent elements of E that have the tag F</li>
- <li> <b>E > F</b> or <b>E/F</b> all direct children elements of E that have the tag F</li>
- <li> <b>E + F</b> all elements with the tag F that are immediately preceded by an element with the tag E</li>
- <li> <b>E ~ F</b> all elements with the tag F that are preceded by a sibling element with the tag E</li>
-</ul>
-
-
-<h4>Attribute Selectors:</h4>
-
-
-<p>The use of @ and quotes are optional. For example, div[@foo='bar'] is also a valid attribute selector.</p>
-
-
-<ul class="list">
- <li> <b>E[foo]</b> has an attribute "foo"</li>
- <li> <b>E[foo=bar]</b> has an attribute "foo" that equals "bar"</li>
- <li> <b>E[foo^=bar]</b> has an attribute "foo" that starts with "bar"</li>
- <li> <b>E[foo$=bar]</b> has an attribute "foo" that ends with "bar"</li>
- <li> <b>E[foo*=bar]</b> has an attribute "foo" that contains the substring "bar"</li>
- <li> <b>E[foo%=2]</b> has an attribute "foo" that is evenly divisible by 2</li>
- <li> <b>E[foo!=bar]</b> attribute "foo" does not equal "bar"</li>
-</ul>
-
-
-<h4>Pseudo Classes:</h4>
-
-
-<ul class="list">
- <li> <b>E:first-child</b> E is the first child of its parent</li>
- <li> <b>E:last-child</b> E is the last child of its parent</li>
- <li> <b>E:nth-child(<i>n</i>)</b> E is the <i>n</i>th child of its parent (1 based as per the spec)</li>
- <li> <b>E:nth-child(odd)</b> E is an odd child of its parent</li>
- <li> <b>E:nth-child(even)</b> E is an even child of its parent</li>
- <li> <b>E:only-child</b> E is the only child of its parent</li>
- <li> <b>E:checked</b> E is an element that is has a checked attribute that is true (e.g. a radio or checkbox) </li>
- <li> <b>E:first</b> the first E in the resultset</li>
- <li> <b>E:last</b> the last E in the resultset</li>
- <li> <b>E:nth(<i>n</i>)</b> the <i>n</i>th E in the resultset (1 based)</li>
- <li> <b>E:odd</b> shortcut for :nth-child(odd)</li>
- <li> <b>E:even</b> shortcut for :nth-child(even)</li>
- <li> <b>E:contains(foo)</b> E's innerHTML contains the substring "foo"</li>
- <li> <b>E:nodeValue(foo)</b> E contains a textNode with a nodeValue that equals "foo"</li>
- <li> <b>E:not(S)</b> an E element that does not match simple selector S</li>
- <li> <b>E:has(S)</b> an E element that has a descendent that matches simple selector S</li>
- <li> <b>E:next(S)</b> an E element whose next sibling matches simple selector S</li>
- <li> <b>E:prev(S)</b> an E element whose previous sibling matches simple selector S</li>
- <li> <b>E:any(S1|S2|S2)</b> an E element which matches any of the simple selectors S1, S2 or S3//\\</li>
-</ul>
-
-
-<h4>CSS Value Selectors:</h4>
-
-
-<ul class="list">
- <li> <b>E{display=none}</b> css value "display" that equals "none"</li>
- <li> <b>E{display^=none}</b> css value "display" that starts with "none"</li>
- <li> <b>E{display$=none}</b> css value "display" that ends with "none"</li>
- <li> <b>E{display*=none}</b> css value "display" that contains the substring "none"</li>
- <li> <b>E{display%=2}</b> css value "display" that is evenly divisible by 2</li>

-Each function is passed two parameters:</p>
-
-<ul>
-<li><p><strong>c</strong> : Array
- An Array of DOM elements to filter.</p></li>
-<li><p><strong>v</strong> : String
- The argument (if any) supplied in the selector.</p></li>
-</ul>
-
-
-<p>A filter function returns an Array of DOM elements which conform to the pseudo class.
-In addition to the provided pseudo classes listed above such as <code>first-child</code> and <code>nth-child</code>,
-developers may add additional, custom psuedo class filters to select elements according to application-specific requirements.</p>
-
-<p>For example, to filter <code>a</code> elements to only return links to <strong>external</strong> resources:</p>
-
-<pre><code>Ext.DomQuery.pseudos.external = function(c, v){
- var r = [], ri = -1;
- for(var i = 0, ci; ci = c[i]; i++){
- // Include in result set only if it's a link to an external resource
- if(ci.hostname != location.hostname){
- r[++ri] = ci;
- }
- }
- return r;
-};
-</code></pre>
-
-<p>Then external links could be gathered with the following statement:</p>
-
-<pre><code>var externalLinks = Ext.select("a:external");
-</code></pre>
