Trackchanges in xml file

Question

I'm interesting is there any library in Java to track changes in xml file. For example we have xml file

 <Package name="Pack3">
    <Process name="Process1"/>
    <Type name="Type1"/>
    <Type name="Type2"/>
  </Package>

then we delete/add tag (I.E. ) So we have this code.

<Package name="Pack3">
    <Process name="Process1"/>
    <Type name="Type2"/>
  </Package>

So i want to track this changes , like in mercurial/github/etc.

It's not hard to do own parser , but ...

Since XML is just a string, you can use some diff analogs like Apache commons difference (org.apache.commons.lang.StringUtils) or java-diff-utils. Find more on string diff here
