Subject RE: Ignoring Specific Tags with Digester
Date Thu, 27 Jul 2006 22:00:50 GMT

Digester seems to be doing exactly what it is supposed to do.  It is
treating XHTML tags just like XML tags (which they are).  If you want to
keep the XHTML information I figure you have a few options:

1.  Write a custom parser (seems like overkill) 
2.  XML-escape the XHTML tags prior to feeding the stream into Digester and
deal w/ them later if necessary.  
3.  Use a more complex data structures so that your objects can represent
paragraph breaks, anchors, etc.  

Those are just a few options that come to mind.

If using these tags causes the feed to not be valid XML, then option 2 is
probably your best bet.

If I'm totally off base, let me know.

I don't think that was the question. I'm guessing the xml is valid, it's 
just not dealing with the xhtml part of it correctly. I'm not too 
familiar with Digester to know the solution however.
