Regular expression to match URLs?	Can't Post

Hi,

I'm using Perl 5.8.6 on Mac 10.6.3. Does anyone have a regular expression that can match URLs ? My ultimate goal is to take a text file, and replace the URLs with the anchor tag (in which the matched URL would be present in the "href" attribute).

Thanks, - Dave

Hi,

If the URL's you are searching for lie inside href tags, then you could use an expression like:

Code

my $anchor = 'myanchor'; 
$html =~ s/(href\=\")([^\"]*)(\")/$1$anchor$3/ig;

If the "text file" you described is a HTML document, then it would be better to use a module such as HTML::Parser to perform the task you outlined.
