Re: [MarkLogic Dev General] Using RegEx in xQuery

Fri, 17 Mar 2017 14:23:47 -0700 

Sure, in the same return, I am getting back 2 HTML elements.  So the first one 
is the one I want to keep.  The 2nd one I would like to do away with entirely.  
At the least to remove all child elements and I could strip the rest on the 
frontend if I had to.  

Here’s a pared-down example of the HTML elements in the same doc.  Is this what 
you wanted to see?

    I can't quite tell from your description what your transformation needs to 
do, though. "Strip out everything in between" what? Can you give a more fleshed 
out example of the input and your expected output?
