The usual advice applies: don't use regular expressions to parse HTML. However,
lots of people do it anyway, myself included. Your success at extracting usable
data depends upon how rigid the format of the HTML is from page to page.
In your case, if the date always follows a link ('</a>') followed by 'on', and
the date is always followed by 'at' and a time. you can use this:
if( $line =~ m{ </a> \s+ on \s+ (\w+ \s \d{1,2} , \s \d{4}) \s at}x ) {
print "The date is $1\n";
}else{
print "No match\n";
}
Note I am using the extended regular expression syntax with the x modifier.
