Pattern-matching an html document
I want to grab the HTML from a web page and insert certain lines into an array.
Code:
#!/usr/bin/perl -w
use LWP::Simple;
$html2009 = get('http://www.ustreas.gov/offices/domestic-finance/debt-management/interest-rate/yield_historical.shtml');
@dates2009 = ();
#scrape dates#
while ($line = $html2009){
if ($line =~ m/^"<td class=\"smaller\" headers=\"1\">\d\d\/\d\d\/\d\d<\/td>"/i){
push (@dates2009, $line);
}
}
print @dates2009;
It occurred to me that I'm not really assigning a single line to $line, but the whole document. How do I read in one line at a time, or is there a better way to extract the data I'm looking for?

@lines=split(/\n/, $html2009);
foreach (@lines) { ... but looking at your pattern match, ^"<td>you want the start of the line to have [/u]"<td>[/u], is that likely You may want to look into HTML::Parser on CPAN, there's a good few of them over there
