Thanks for your help. but this query will probably select "abcfooxyz" as well when "foo" is supplied. (untested), although it will definitely select "foo" in "foo bar" (tested)
$xpath->query("//div[contains(@class, '" . $class . "')]")
How can we be more specific? Try this example: http://westhoffswelt.de/blog/0036_xpath_to_select_html_by_class.html
@URL: Actually I am maintaining the module feedapi imagegrabber, which downloads images from external websites. Now sometimes the url I parse has spaces, so I am unable to decide whether or not to percentage encode the URL, because percentage encoding will make this URL valid but will break the following URL: http://www.google.com/search?q=hello by converting it to http://www.google.com/search?q%3Dhello "q=hello" is a query string, not strictly part of the path. I would strip the url to its component parts (parse_url) and encode the path, then re-append the query string.

Looking forward.

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>
The "contains" function would probably work, eg (untested): $xpath->query("//div[contains(@class, '" . $class . "')]");
One more question: is this url valid : http://xyz.com/path with
space.html
Nope. You can escape the url if you just HAVE to have spaces:
http://n00b.com/path%20with%20space.html
but why not use dashes?
