storing xml - how to highlight hits in response?

[Matt Mitchell <go...@gmail.com>]

Hi,

I'm storing some raw xml in solr (stored and non-tokenized). I'd like to
highlight hits in the response, obviously this is problematic as the
highlighting elements are also xml. So if I match an attribute value or tag
name, the xml response is messed up. Is there a way to highlight only text,
that is not part of an xml element? As in, only the text content?

Perhaps a much simpler option would be to use this:

http://lucene.apache.org/solr/api/org/apache/solr/analysis/PatternReplaceFilterFactory.html

with a regex of "<[^>]*>" or something like that - I'm no regex expert.  Of course it could get tricky to handle escaped characters and the like, but it may be a good enough poor man's solution.

Yeah great idea, thanks. Does anyone know if there is code out there that
will do this sort of thing?

You could create a custom Analyzer or Tokenizer that strips everything but the text content.
