I'm looking to filter items in a Content Query Webpart by URL, e.g. URL contains this particular string. URL is not available in the list of fields though. Specifying 'FilterField1="URL"' in the source code also does not work. Adding URL to CommonViewFields makes no difference.
My WebPart points to a Document library with mostly doc files and images. Is there a way to do this using the WebPart filter?
I know I could conceivably filter in xslt (because the URL is available here), but it would be slower, plus I need the top 10 items that match the filter.
