Perl question

[Eric Schwartz]

Hello all,
         Thank you for your help in this matter.  I have decided to move 
forward with using "html scraping"  I am using this code from a book on 
perl, and i cant seem to get it to work.  I tried to modify it to search 
specifically for estimated pages remaining, and I want it to look for the 
group of numbers that is right after, but i dont seem to be doing anything 
right.  When I run this code it prints "here it is" and nothing 
else.  Maybe because it just finds a blank space after the designated 
search, im not sure.  Here is a small clip of the html i am looking at:

<td width="90%">
<p align="left"><font face="Arial,Helvetica" size="1" color="#000000">
Estimated Pages Remaining:
</font></p>
</td>
<td width="10%">
<p align="right"><font face="Arial,Helvetica" size="1" color="#000000">
6052
</font></p>
</td>
</tr>


MY CODE:

my $html = get("ipaddress");
$html =~ m{Estimated Pages Remaining:<td width="90%"> ([\d,]+) </font><br>};
my $blkpgsrem=$1;
#$blkpgsrem =~ tr[,][]d;
print "here it is:$blkpgsrem\n";


PS:
I also have found this code in the book i am looking into, but I cant seem 
to understand it.

$text = qq(<a href="file.html"><b>Dog</b></a>Woof\nWoof</p>);
($file, $title, $summary) =
     $text =~ m{<a href="(.*?)"><b>(.*?)</b></a>\s*(.*?)</p>};
It looks like it is searching for multiple things and assigning different 
variables to each seach parameter, however i do not know how to make this 
apply to my HTML.

Again, I appreciate all the help you guys have been giving me,  Thank you.

Eric
