We even get the information what subrules matched, and since these are also Match objects we can obtain
their match position in the text.

Trivial example using PHP's built-in filter_var() function (which does not support IRIs).
<lang PHP>$tests = array(
'this URI contains an illegal character, parentheses and a misplaced full stop:',
'http://en.wikipedia.org/wiki/Erich_Kästner_(camera_designer). (which is handled by http://mediawiki.org/).',
'and another one just to confuse the parser: http://en.wikipedia.org/wiki/-)',
'")" is handled the wrong way by the mediawiki parser.',
'ftp://domain.name/path(balanced_brackets)/foo.html',
'ftp://domain.name/path(balanced_brackets)/ending.in.dot.',
'ftp://domain.name/path(unbalanced_brackets/ending.in.dot.',
'leading junk ftp://domain.name/path/embedded?punct/uation.',
'leading junk ftp://domain.name/dangling_close_paren)',
'if you have other interesting URIs for testing, please add them here:',
'http://www.example.org/foo.html#includes_fragment',
'http://www.example.org/foo.html#enthält_Unicode-Fragment',
' http://192.168.0.1/admin/?hackme=%%%%%%%%%true',
'blah (foo://domain.hld/))))',
'https://haxor.ur:4592/~mama/####&?foo'
);
foreach ( $tests as $test ) {
foreach( explode( ' ', $test ) as $uri ) {
if ( filter_var( $uri, FILTER_VALIDATE_URL ) )
echo $uri, PHP_EOL;
}
}
