NAME URI::Find - Find URIs in arbitrary text SYNOPSIS require URI::Find; my $finder = URI::Find->new(\&callback); $how_many_found = $finder->find(\$text); DESCRIPTION This module does one thing: Finds URIs and URLs in plain text. It finds them quickly and it finds them all (or what URI::URL considers a URI to be.) It only finds URIs which include a scheme (http:// or the like), for something a bit less strict have a look at URI::Find::Schemeless. For a command-line interface, see Darren Chamberlain's "urifind" script. It's available from his CPAN directory, <http://www.cpan.org/authors/id/D/DA/DARREN/>. EXAMPLES Store a list of all URIs (normalized) in the document. my @uris; my $finder = URI::Find->new(sub { my($uri) = shift; push @uris, $uri; }); $finder->find(\$text); Print the original URI text found and the normalized representation. my $finder = URI::Find->new(sub { my($uri, $orig_uri) = @_; print "The text '$orig_uri' represents '$uri'\n"; return $orig_uri; }); $finder->find(\$text); Check each URI in document to see if it exists. use LWP::Simple; my $finder = URI::Find->new(sub { my($uri, $orig_uri) = @_; if( head $uri ) { print "$orig_uri is okay\n"; } else { print "$orig_uri cannot be found\n"; } return $orig_uri; }); $finder->find(\$text); Turn plain text into HTML, with each URI found wrapped in an HTML anchor. use CGI qw(escapeHTML); use URI::Find; my $finder = URI::Find->new(sub { my($uri, $orig_uri) = @_; return qq|<a href="$uri">$orig_uri</a>|; }); $finder->find(\$text, \&escapeHTML); print "<pre>$text</pre>"; AUTHOR Michael G Schwern <[email protected]> with insight from Uri Gutman, Greg Bacon, Jeff Pinyan, Roderick Schertler and others.
