in reply to Files! Reading specific parts

If you want to grab an arbitrary amount of text around something for which you are searching, just specify it in the regex. If you want the leading and trailing, say, 100 characters... 

/(.{0,100}$key.{0,100})/

Afterwards, because of the parens, your match will be in the variable $1.

    Good idea, but i probably should have explained myself better. I need to filter out HTML as i read in the keyword. Something like this.... get keyword, go back some spaces, filter out the html and other keywords so its plain text, then go ahead of the word a bit and do the same.

      Then you should probably use some HTML parser class or other (HTML::Parser comes to mind), strip out all of the markup, and then use my previous suggestion. It should just be a matter of plugging together two modular solutions to solve a third problem that is really just two problems rolled into one.
