This has been bothering me for days. I just need to find out what are the missing nodes in the second xml by comparison. I tried xmlunit but it doesn't really help me find the missing node since it compares line by line. two sample xml below: xml1:

<test testcase="101">
    <value="1">
    <value="2">
    <value="3">
</test>

xml2:

<test testcase="101">
    <value="3">
    <value="2">
</test>

Note that value=3 is actually there in the second copy it just get to the first node but still I consider it's not missing. how do i find the missing node value="1"?

You may want to compare `List` of values : http://stackoverflow.com/questions/919387/how-can-i-calculate-the-difference-between-two-arraylists – Arnaud Jun 13 '16 at 15:50

How big the xml are? – wake-0 Jun 13 '16 at 15:51
Also are values in your nodes unique? If so the `Set` might be a better option than `List`. – Aleksandr Erokhin Jun 13 '16 at 15:52
it's a relatively small xml and yes the nodes are supposed to be unique. – shanechamp430 Jun 13 '16 at 23:43

If you tell XMLUnit to match nodes based on their name and the value of the `value` attribute then it should do the trick. See https://github.com/xmlunit/user-guide/wiki/SelectingNodes – Stefan Bodewig Jun 14 '16 at 04:16
I think this is what I need. you rock man. – shanechamp430 Jun 14 '16 at 14:12
