Compare two hierarchial files

[karthik.prabaharan]

Hello,

Can someone throw some light on how to compare the two files (File1.txt
and File2.txt) I have mentioned below:

The 2 files are existing in the hierarchical format and I am not able
to use any of the diff tools to point out the difference.

File1.txt
---------

*********
SubClasses of Class: [WorkspaceObject]
*********

<a Taxonomy WorkspaceObject: WorkspaceObject
Text1
Sub1
Sub2
Sub3
Text2
Sub3
Sub4
Sub-sub1
Text3
Text4File 2.txt

*********
SubClasses of Class: [WorkspaceObject]
*********

<a Taxonomy WorkspaceObject: WorkspaceObject
Text3
Sub1
Sub2
Sub-sub1
Text1
Sub1
Sub2
Sub3
Text2
Text4

Highly appreciate anybody's help.
