I got over 100s of HTML files in the following format:
<HTML> <HEAD> <TITLE>Statistics for ABC LTD - January 2007 - Rang IDXYZZAZZZZ</TITLE> </HEAD> <BODY BGCOLOR="#E8E8E8" TEXT="#000000" LINK="#0000FF" VLINK="#FF0000"> <H2>Statistics for ABC LTF</H2> <SMALL><STRONG> Summary Period: January 2007<BR> Generated 01-Feb-2007 06:40 CET<BR> </STRONG></SMALL> <CENTER> <HR> <P> <FONT SIZE="-1"></CENTER><PRE> my data 1 my data 2 my data 3 my data 10000 my data N times

Easy and practical, thanks.
I just wanted to know is it possible to use `awk` instead of `sed` ?

Thanks for a simple & elegant solution. But it prints START-WORD & END-WORD as well. Is there a simple way to exclude these, by including something simple like \zs or \ze (of ViM) in the START-WORD & END-WORD?
I have the same inquiry as Surya — how do you omit the start and end regexp’s?
Replace the words START-WORD & END-WORD with your keyword.
Whenever I use the sed or awk version of
/word1/,/word2/
say i have a file
word1 and word2
it prints
word1 and word2
and not just
and
@SSengupta: I don’t think you understand the question that Surya, myself, and now billy have asked. Conduct the example above:
– copy the example html into a file, input.html
– execute the sed command to “extract the text between `pre` and `/pre`”
– You end up with “
”
For something where this is just one “chunk” and you can just remove on set of `pre` and `/pre` matches, not a big deal. But I was doing this on a big file with tons of matches and thus keeping the “bookend” text really doesn’t help me much.
A workaround is to do the `sed` command above, and then go back through with two other steps:
– sed -i “s/
,,g” output.html
(Use commas for second command since typical separator, “/” is used in the closing pre tag)
Yeah, that went horribly… Trying once more:

You get the idea… just manually sed the pre tags out afterward. Sorry, huge comment fail…
In contrast to what is stated in this article, grep is actually a perfect tool for this job! It supports both positive and negative look-ahead and look-back. To extract text from in between HTML tags, for example:
Now. I don’t know if it’s faster than sed or awk, but it works! :-)
It seems my code was interpreted as HTML and not fully displayed. I really don’t know a way around that, so never mind, I guess.
Put it between pre html tags.
