add line number display to validation result window

[4rz0]

At the moment, the validation result window only lists errors, but it's hard to see where the error happened.
Line numbers would be very helpful for that, especially if it supports clicking to jump to line.

I'm aware of that and I already spent a lot of efforts on that issue, with not success for the moment. Actually libXML validation tools seem to be quite limited on that point. I'll try again when I've time.
Note that I'm also studying the possibility of migrating to xerces/xalan in replacement of libXML, but it's quite a big job.

Hello, to validate the XML file, you can use the Microsoft MSXML library, which has the ability to display the order and the position of the error.
