Hi,
I've never used perl before, but was told that it's pretty powerful for text
processing.
Here's a problem I'm trying to solve:
I have an expression, exp1 that I need to grep for recursively over a
directory structure. If I find a match, I need to look at the matching file
and find another expression, exp2. Both exp1 and exp2 belong to the same
pattern that always looks like this
{
exp2 "some text"
some lines of text
some lines of tex
.....
exp1
more lines of text
more lines of text
....
}
The goal of this exercise is to see what "some text" says in the files that
contain exp1.
I can always read all of the files recursively line by line, save each line
into an array until I find exp1 and then go backwards through the array until
I find exp2 and see what "some text" on that line is, but I was wondering if I
can somehow use regular expressions over multiple lines to do this.
I hope this is a clear explanation of my problem.
Any insights or pointers to resourcesare greatly appreciated!
Thanks!
