How do I extract xml tag using regex?

merrin

I tried to extract xml tagNames as fields fieldNameStartTag and fieldNameEndTag using the following.

rex field=_raw "<(?.)>([^<]+)</(?.)>"
But it does not extract all tags correctly. For example I have this xml:

abc
xyz

What I'm looking for is fieldNameStartTag and/or fieldNameEndTag to have values "ChildOne" and "ChildTwo". But the regex above gives me values like these:
1. Parent xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.abcd.com"> abc
2. ChildOne>xyz

Any help is appreciated.

You should use the spath command, if you're on 4.3 or higher. If you're on older versions, the xmlkv command will also work for you.

Have you checked out the xmlkv command? This allows you to automatically extract KV pairs from XML formatted data without any regex's:
