title: Comparing two xml files using JAVA
body: <p>I have to xml files say abc.xml &amp; 123.xml which are almost similar, i mean has the same content, but the second one i.e, 123.xml has more content than the earlier one.
  I want to read both the files using Java, and compare whether the content present in abc.xml for each tag is same as that in 123.xml, something like object comparison. 
  Please suggest me how to read the xml file using java and start comparing.</p>
