To tell you the truth a friend helped me with the commands, I'm not even really sure to understand the difference between egrep and grep as I get the same results using "grep"... I mean, I've read the manual and I understand that egrep can handle more complex expression than grep but I'm not sure of what an "extended regular expression" is... :S
I will definitely search the forum to get more info, but what I was thinking was to get into a while loop so that I can get the price (and more details) of each listing that my command already provides.
I was thinking of first printing the output into an XML but can't seem to find the command to output my grep.
EDIT: I forgot, I also thought of using "sed" to get extract only the info that I'm looking for.

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
