Can you parse the contents of a field to populate other fields?

Hello - 

I'm wondering if this is possible... I am trying to model a
hierarchy of
facets, and have a field in my xml (Category) that
structured like this:
facet1::facet2::facet3...  At index time, I would like to
split this
field on the :: to populate several other fields I have
defined in my
schema (Category_1, Category_2, Category_3).  Is this
possible?  If so,
what is the best way to do this?

 

Thanks!

Kristen

I think a PatternTokenizer might be able to do this...
set up a copyField from Category to all the other category
fields, and
then set up a different regex on each field to pull out the
right
part.
