XPath Checker 0.4.1

XPath Checker is a Firefox Extension I wrote for testing XPath expressions interactively. You might find it useful if you use xpaths or want to learn how.

If you havent used xpaths before, they are sort of like regular expressions for web pages. XPaths make it easy to extract content from deeply nested markup in a web page or an XML document. I find them most useful for unit-testing code that generates XML or HTML. Theyre also used in XSLT and by Firefox extensions such as Greasemonkey.
