Perl script to list all files in a website

I have a website where some files are listed
say

Code:

GTP-UGP-LATEST-5.3.0.123.iso 

GTP-UGP-LATEST-5.3.0.127.iso 

GTP-UGP-LATEST-5.3.0.132.iso 

GTP-UGP-LATEST-5.3.0.136.iso  

PRE-UGP-LATEST-5.3.0.124.iso 

PRE-UGP-LATEST-5.3.0.126.iso 

PRE-UGP-LATEST-5.3.0.127.iso 

PRE-UGP-LATEST-5.3.0.130.iso

I am trying to write a perl script that can parse the HTML file and list all the files whoes name start from "GTP-UGP-LATEST-" and end from ".iso" and write it into a local file say gtp.txt.

Similary list all the files whoes name start from "PRE-UGP-LATEST-" and end from ".iso" and and write it into a local file say pre.txt.

Any idea how to parse with a HTML parser?

If the stated intention is the whole job, then I would simply use grep:

Code:

grep "PRE-UGP-LATEST-.*\.iso" yourFile.html > gtp.txt

If you really want to use Perl, then you should visit CPAN.org, and select one of the fine ready-made HTML parser modules there. Reliably parsing HTML is non-trivial, and you will do yourself a favor to use the existing work of experts.
