I'm working on finding differences in 2 xml files. I need to check for new text, new tags, new attributes, etc., whichever is new. I can find that there is a change. But I can't locate the exact line-number. Is there any way?
File1.xml
<?xml version="1.0" encoding="UTF-8"?>
<file1>
  <file11 href="ha">test1</file11>
  <file12 href="">test2</file12>
</file1>
File2.xml
<?xml version="1.0" encoding="UTF-8"?>
<file1>
  <file21>test2</file21>
  <file22 href="hai">test1</file22>
</file1>

You don't say anything about the technology you are using.

Most of the standard tree models (DOM, JDOM, etc) don't give you any line number information.

It's available from SAX and StAX parsers, but that's a bit low-level.

If you're using Saxon, there's an option to maintain line numbers and retrieve them using the saxon:line-number() extension function.

Incidentally, there are products like DeltaXML that do this for you, and much better that you could hope to achieve in something home-grown.

Thanks Mike. I'm using XSLT 2.0 with Saxon processor.
I can't opt for products like DeltaXML. Is there any way to do it through code?

thanks in advance

In Saxon you can cause line numbers to be maintained using -l from the command line or the equivalent from the API (e.g TransformerFactory.setAttribute("http://saxon.sf.net/feature/linenumbering", Boolean.TRUE), and you can then access the line number using saxon:line-number(), as already mentioned.
