Yin,

I should be able to delete any attribute and its content from the below example.

Input:
Code:
 
<xmlfile> ows_Body="Hi All" ows_Title="Title: Execution of Unix" ows_Author="krishna" </xmlfile>

Say If I have to delete ows_Body and its content from the input, output should be

Code:
 
<xmlfile> ows_Title="Title: Execution of Unix" ows_Author="krishna" </xmlfile>

And If I have to delete ows_Title & its content from the input, the output should be

Code:
 
<xmlfile> ows_Body="Hi All" ows_Author="krishna" </xmlfile>

Thanks,
Mahish

Appreciate your help on this.
But the solution given by you works for ows_Body= , but dont work for ows_Title.

Whatever the search element I give.. ows_Body or ows_Title, it should delete it and the data after "=" for it

Code:
 
 <xmlfile> ows_Body="Hi All" ows_Title="Title: Execution of Unix" ows_Author="krishna" </xmlfile>

If I have delete ows_Title, output should be
Code:
 
 
<xmlfile> ows_Body="Hi All" ows_Author="krishna" </xmlfile>

Also here ows_Title may not be always followed by ows_Author in the input..
We should be able to delete any data from ows_Title to next occurance of ows_
