Thanks for your help. but this query will probably select "abcfooxyz"

$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.

HTH,

Looking forward.
