NAME ^

URI::Find::Iterator - provides an iterator interface to URI::Find

SYNOPSIS ^

    use URI::Find::Iterator;

    my $string = "foo http://thegestalt.org/simon/ bar\n";
    my $it     = URI::Find::Iterator->new($string);

    while (my ($uri, $orig_match) = $it->match()) {
        print "Matched $uri\n";
        $it->replace("<a href='$uri'>$uri</a>");
    }

    # prints
    # foo <a href='http://thegestalt.org/simon/'>http://thegestalt.org/simon</a> bar
    print $it->result();

DESCRIPTION ^

Inspired by Mark Jason Dominus' talk Programming with Iterators and Generators (available from http://perl.plover.com/yak/iterators/) this is an iterative version of URI::Find that hopefully makes code a little easier to understand and works slightly better with people's brains than callbacks do.

METHODS ^

new <string> [%opts]

Takes a string checking as an argument. Optionally can also take a class name to extract regexes from (the class must have uri_re and schemeless_uri_re methods).

    URI::Find::Iterator->new($string, class => "URI::Find::Schemeless"); 

would be the canonical example.

Alterantively it could take a straight regexp of your own devising

    URI::Find::Iterator->new($string, re => "http://[^ ]+");

match

Returns the current match as a tuple - the first element of which is a URI::URL object and the second is the original text of the URI found.

Just like URI::Find.

It then advances to the next one.

replace <replacement>

Replaces the current match with replacement

result

Returns the string with all replacements.

BUGS ^

None that I know of but there are probably loads.

It could possibly be split out into a generic Regex::Iterator module.

COPYING ^

Distributed under the same terms as Perl itself.
