Comparing two xmls based on keys....

[Nick]

Hi,

I need to compare two xml files. Which contain multiple xml datas
based on a key.

So for eg. I have two xmls A.xml and B.xml.

A.xml :
<?xml version="1.0" encoding="UTF-8"?>
<Test >
<Item>1</Item>
<Name>Orange</Name>
</Test>
<Test >
<Item>2</Item>
<Name>Apple</Name>
</Test>

Whereas B.xml :

<?xml version="1.0" encoding="UTF-8"?>
<Test >
<Item>2/Item>
<Name>Apple</Name>
</Test>
<Test >
<Item>1</Item>
<Name>Orange</Name>
</Test>

If you compare tags row by row then the xmls won't match but if you
keep the Item as the key then both the xmls are equal.
Item : 1 / Name : Orange
Item : 2 / Name : Apple

How can you do such comparison in Java

Sounds like a class assignment. Shouldn't be hard. I'd suggest using a
SAX parser to load the data from the first document into an
application-specific data structure, then to load the data from the
second document and check it off against the first. Don't forget to
handle the cases of more items present, fewer items present, and
duplicate items. Have fun,
