[thelist] Perl Regex

Memo from Martin P Burns of PricewaterhouseCoopers

-------------------- Start of message text --------------------

Another couple of Perl niceities are $` and $' which give you the content
on the line before and after (respectively) the pattern the regexp finds.
In this case:

$string = "<TITLE>Test title</TITLE>";
$string =~ s/<[^>]+>//g;
print "$string\n";
print "$`\n";
print "$'\n";

will give the result:

Test title
<TITLE>
</TITLE>

Cheers
Martin

$string = "<TITLE>Test title</TITLE>";
$string =~ s/<[^>]+>//g;
print "$string";

Result:
   "Test title"

The expression matches all occurrences of a "<", followed by one or more
characters that aren't a ">", followed by a ">". If you don't have the "g"
at the end, it will only match the first occurrence.
