Can you tell me how to extract the text portion from the html page?

Let's consider the possibilities. <BR><BR>These files are kept safe from downloading from online directories before modifying/uploading to server.<BR>i.e. safe live copies of the core, changeable, data.<BR><BR>In the event of a freeze, re-uploading should revert to the original and workable state.<BR><BR>April 25 2005<BR><BR>03.05.2001<BR><BR>These files taken from various sources-see notes.<BR>Should be ready to rock. <BR>All safety copies ready.<BR>(only .txt, and new updated QAGRID.DAT + QALOCTAB.DAT are untried)<BR><BR>Mr,B,Hagerty,Hawthorns,5 Granborough Road,North Marston,Bucks,MK18 3PN,On the back of a lorry that pulled out in front of me on the M25</I><BR><BR> <FONT SIZE=5 FACE="verdana"> Header 2:</FONT><P> Application Procedure:<BR><BR>When filing an application form, the student should specify the department or doctoral program subcommittee under which he or she wishes to study.

You could look into the HTML library. HTML:
 arse is used for, that's right, parsing HTML. I've never actually used them so I couldn't very well direct you on that. This would be your best bet, especially if you are dealing with files of variable formatting and length.If you are dealing with only this file, or a situation where the headers are in the same general format as far as number of lines used, then you could just count lines and write regular expressions to get the info you need and remove the tags you don't want. Doing this wouldn't be any good if you are dealing with a number of disimilar files, so I wouldn't suggest it unless the script will be used specifically for only ONE or ONE TYPE of file.

A Load of GREP
Use GREP to find the esential tags and strip out the rest:
/<title>(.+)<\/title>/i; # $1 contains Title s/<[^>]+>//g; # All other tags are stripped out The first match leaves the title in $1, the second strips out everything within < & > brackets.
