Compare huge XML files through java

Hi,
I have 2 XML files of 16 mb each having a list of user profile information. I need to compare these files to check whether user profiles present in XML file1 are also present in  XML file2 and should identify the profiles which are different. What is the best approach for this?
Note: profile consists of name, age, phone no etc

Whether you use the faster and lighter pull method or sax, you might find it necessary to construct a partial dom, in which case you'll need to maintain you own stacks
