Master .... I am here to server your demands ...


Would you prefer String based, or DOM based, or SAX based comparison ?

How do you define "compare" ? Node names, node content, or purely byte data level ?

Sure: diff for Unix, fc for MS-DOS.

Cheers,

while you're at it sedj, can i get that in a nice color coded gui with pretty lines to show the differences?

You could use Visual Source Safe if you want a nice color coded gui with pretty lines to show the differences!

Follow these steps:
1. Load one of the xml files into Visual Source Safe

2. Check the file back out to your dekstop

3. Delete the file you just checked out

4. Copy the other xml file to your desktop and rename it so it has the same name as the file you just deleted in step 3

5. Do a "check in" in Source Safe, this will cause the second file to replace the first one.

6. Choose Show History, click OK, select both versions of the file and then click the button labeled "Diff"

7. Enjoy your happy colered GUI

sedj-
I am looking for DOM based, or SAX based comparison.

What i meant by compare is ,comparing nodes and node content and displaying the difference i.e <Node><Child>, <Node><Child><Child>

You probably want to use DOM, as using SAX may give you problems to synchonously access two xml files.

I think you should read the DOM API tutorial, work out how to rip through a DOM, and then you will be away :
