Is there an online tester for xPath selectors?

I know there are some online regex evaluators.. very useful, matching in real time. They are like web applications of RegexBuddy.

I was wondering if there is a similar thing for xPath selectors? I am just learning them and it would be valuable to me.

Is there an online tester that allows you to input XML and then an xPath selector and match (live would be better, but I doubt someone has written a JavaScript interpreter?) them?

Thanks

I notice that the only "online" checker in the answers seems a bit clunky. It requires submission to a server, and it doesn't handle namespaces properly.

I thought I could do better, and that such a tool would be quite useful, so I made one. I realize it is slightly self-promoting to mention it here, but it does specifically answer the question, I think!

Mine can apply an xpath expression to an arbitrary XML document and display the results. It can also beautify, or pretty-print an XML document, and apply an XSLT transformation to it. All processing is done by the browser, and it should work in IE6+, Firefox, Opera, Chrome, and Safari.

Please let me know if you encounter any issues with it!

This is not an online tool; instead it's a Windows app, more along the lines of RegexBuddy, but for XPath.

XPathVisualizer.

Edit: The XPath Visualizer for IE now has a new, safer home, thanks to the kindness of Lars Huttar. Also there is the XPath Visualizer for FF.

The XPath Visualizer has been available for more than 10 years and has helped thousands of people learn XPath the fun way. Available for IE and for FireFox.

The XPath Visualizer is a popular tool for learning XPath by playing with XPath expressions. Free and open source.

Allows any XPath expression to be evaluated against a given XML document and displays the results hi-lighted in the xml document (if they are node(s)) or in a separate box (if the results are atomic values).

Allows xsl:variable-s to be defined and then used in XPath expressions.

Allows xsl:key-s to be defined and then referenced by key() functions within XPath expressions.

Yep! Try the XPath Checker extension for Firefox. It's a handy tool.

Here is a nice one: http://www.xpathtester.com/

You can also use Notepad++ with it's XMLTools plugin - it has xPath evaluator

i use this one

Here is one...

XPath Query Expression Tool

I found the following tool the most helpful.

Allans Online XPath Tester

The other tools mentioned below either required a particular browser or had some issue with loading xml or using some of the more obscure XPath expressions I was using. This tool did not.

Remove It Permanently, a firefox extension available on AMO, has such visualization functions. It would be nice if it had firebug type power for the slightly advanced adblocker.

If you're on Firefox, you can use [Firebug][1] + [Firefinder][2], which enable you to filter elements based on XPath expressions, and even post the matched code to [jsbin][3] in a snap.
