This is a really simple Windows application for testing xpaths. Don't expect much, it just works for what I needed it. Maybe more features will be added in the future if I feel the need for them. No requests, though. Sorry.
There is no installation, only an executable inside a zip. Extract it and run it.
Populate the XPath and XML Input fields, then hit the Run button. If all goes well, the resulting nodes are shown in the Result textbox, If not, an error popup is shown. Empty textbox means there were no results.
No explicit license. Use as you please, no guarantees on anything, if it doesn't work for you or your computer explodes, I'm not to blame. I don't see a reason for anything like that to happen, but still, it's your responsibility.
