CssQuery () is a powerful cross-browser JavaScript function that enables querying of a DOM document using CSS selectors. All CSS1 and CSS2 selectors are allowed plus quite a few CSS3 selectors.

Elements = cssQuery (selector [, from]); where selector (required) is a valid CSS selector and from (optional) is a document, element or array of elements which is filtered by selector.

The function returns a JavaScript array of elements. If there is no match, an empty array is returned.

Some examples:

// Find all paragraphs that are direct descendants // of the document bodyvar tags = cssQuery ("body> p "); // find all elements with the "href" attributevar tags = cssQuery ("[href]"); // find all anchor elements with "href" equal to "#" var tags = cssQuery ("a [href = '#']"); // find all images contained by the above anchorsvar images = cssQuery ("img", tags); // find all listsvar tags = cssQuery ("dl, ol, ul "); // Query an external xml documentvar tags = cssQuery ("my |: root> my | link", myXMLDoc); // just plain complicatedvar complex = "p>: first-child + input [type = text] ~ Span "; var tags = cssQuery (complex); Allowed Selectors
