I am using the xml-tools plugin in notepad++ to run validation on .xml files using an .xsd schema file.
But I have hundreds of files to validate, and will likely have hundreds more.
I really like how Notepad++ handles “find all in all documents” and was wondering if there was a way to do a run-plugin-function-in-all-opened-documents within notepad.
Alternately, if there is another, better way of mass validating .xml that would solve the problem
There are command line tools, which could be used via a batch/shell script depending on your environment. This is implemented in perl and should do, here is a link to a Win32 installer.
