Steve, since I am not quite sure what you want to do, you may wish to check out
XML::LibXML. This module allows parsing of xml|html fragments into an XML Dom
structure. You can then perform xpath node lookups based on your criteria and then
drill down to get the data you need. IF you want the value of every list item, no
matter what its parent contains, then using xpath would be a perfect fit, at the cost
of adding more code and possibly learning a new skillset (all things considered,
learning to use XML::LibXML is a VERY good thing). Besides that, if someone changes
the html in any way (adding a new attribute to the tag for example), then you would
have to go back and debug your script. Plus, you would avoid a good deal of possible
backtraking and backreferences. This may be negated by the size of the html string
passed since using a DOM increases the in memory size by several times.
I use XML::LibXML to parse jobpostboards currently to drill down into several layers
or pages (using LWP) and verify my clients jobs are all posted by compairing data on
each page to a DB generated list of jobs that should be on the board. If thing you
might go that way, get the ppm from the http://theoryx5.uwinnipeg.ca/ppmpackages/
repository(there are two repositories now, one for 5.6 and one for 5.8. If Randy or
anyone else is listening, can you give the correct URL for each?)
Joe
