[development] Xpath query for class matching

[nitin gupta]

Hi all,
For the module I am maintaining at drupal, I need to select the element
which has a specific class. I am using the following query for it:

for eg <div class="foo"></div> is selected by the following query.

$class = "foo";
$xpath->query("//*[@class = '".$class."']");

But, this fails in case of multiple classes, i.e. does not select this :

<div class="foo bar"> </div>


I don't have much experience in writing regex, can someone please help me
out with this.


One more question: is this url valid : http://xyz.com/path with space.html

Looking forward.
