construct for block scans

[satyanandam.gullapudi]

I am trying to scan multi line data from a text file for certain blocks
among others. There is some kind of loop construct in perl with
implicit state variable. The one where you specify a matching criteria
for block begin and matching criteria for block end. Can anyone give
the usage ?

There is some kind of loop construct in perl with implicit state variable.

I don't know what that means.

The one where you specify a matching criteria for block begin and
matching criteria for block end.

Do you mean a "regular expression?"

perldoc perlre
perldoc -q "matching over more than one line"

Or do you mean parsing between matching/nesting tags?

perldoc -q 'How do I find matching/nesting anything'

It sounds like you want ".." in a scalar context. See perldoc perlop,
it provides both documentation and examples.
