Usage

Using pattern:

use Madkom\RegEx\Pattern;

$pattern = new Pattern('<((?=[^!])(/)?([^>]+))>');
$pattern->getPattern(); // "/<((?=[^!])(\/)?([^>]+))>/"

Matching pattern:

use Madkom\RegEx\Matcher;
use Madkom\RegEx\Pattern;

$pattern = new Pattern('<((?=[^/]+)[^>]+)>');
$matcher = new Matcher($pattern, 's');

$subject = <<<EOL
<!DOCTYPE html>
<html>
<head><title>Ala ma kota</title></head>
<body><h1>Ala ma kota</h1></body>
</html>
EOL;

$match = $matcher->match($subject);

//array:2 [
//  0 => "<!DOCTYPE html>"
//  1 => "!DOCTYPE html"
//]

Matching pattern capture all matches:

use Madkom\RegEx\Matcher;
use Madkom\RegEx\Pattern;

$pattern = new Pattern('<((?=[^/]+)[^>]+)>');
$matcher = new Matcher($pattern, 's');

$subject = <<<EOL
<!DOCTYPE html>
<html>
<head><title>Ala ma kota</title></head>
<body><h1>Ala ma kota</h1></body>
</html>
EOL;

$match = $matcher->matchAll($subject);

//array:2 [
//  0 => array:6 [
//    0 => "<!DOCTYPE html>"
//    1 => "<html>"
//    2 => "<head>"
//    3 => "<title>"
//    4 => "<body>"
//    5 => "<h1>"
//  ]
//  1 => array:6 [
//    0 => "!DOCTYPE html"
//    1 => "html"
//    2 => "head"
//    3 => "title"
//    4 => "body"
//    5 => "h1"
//  ]
//]

Replace with replacement:

use Madkom\RegEx\Replacer;
use Madkom\RegEx\Pattern;

$pattern = new Pattern('<((?=[^!])(/)?([^>]+))>');
$replacer = new Replacer($pattern, 's');

$subject = <<<EOL
<!DOCTYPE html>
<html>
<head><title>Ala ma kota</title></head>
<body><h1>Ala ma kota</h1></body>
</html>
EOL;

$replaced = $replacer->replace($subject, '<\\2xhtml:\\3>');

//<!DOCTYPE html>\n
//<xhtml:html>\n
//<xhtml:head><xhtml:title>Ala ma kota</xhtml:title></xhtml:head>\n
//<xhtml:body><xhtml:h1>Ala ma kota</xhtml:h1></xhtml:body>\n
//</xhtml:html>

Replace with handler:

use Madkom\RegEx\Replacer;
use Madkom\RegEx\Pattern;

$pattern = new Pattern('<((?=[^!])(/)?([^>]+))>');
$replacer = new Replacer($pattern, 's');

$subject = <<<EOL
<!DOCTYPE html>
<html>
<head><title>Ala ma kota</title></head>
<body><h1>Ala ma kota</h1></body>
</html>
EOL;

$replaced = $replacer->replaceWith($subject, function ($match) {
    return "<{$match[2]}xhtml:{$match[3]}>";
});

//<!DOCTYPE html>\n
//<xhtml:html>\n
//<xhtml:head><xhtml:title>Ala ma kota</xhtml:title></xhtml:head>\n
//<xhtml:body><xhtml:h1>Ala ma kota</xhtml:h1></xhtml:body>\n
//</xhtml:html>

Splitting:

use Madkom\RegEx\Splitter;
use Madkom\RegEx\Pattern;

$subject = "html, simple, kayword, complex keyword, keyword with ; semicolon";

$pattern = new Pattern('([,]\s*)');
$splitter = new Splitter($pattern);
$splitted = $splitter->split($subject);

//array:5 [
//  0 => "html"
//  1 => "simple"
//  2 => "kayword"
//  3 => "complex keyword"
//  4 => "keyword with ; semicolon"
//]

Grepping array:

use Madkom\RegEx\Grepper;
use Madkom\RegEx\Pattern;

$subjects = [
    '<a href="http://madkom.pl">madkom.pl</a>',
    '<a href="http://google.pl">google.pl</a>',
    '<a href="http://bing.com">bing.com</a>',
    '<a href="https://example.pl">example.pl</a>',
    '<a href="https://example.org">example.org</a>',
];

$pattern = new Pattern('(http[s]?://[a-z0-9]+\.pl)');
$grepper = new Grepper($pattern, 'iU');
$grepped = $grepper->grep($subjects);

//array:3 [
//  0 => "<a href="http://madkom.pl">madkom.pl</a>"
//  1 => "<a href="http://google.pl">google.pl</a>"
//  3 => "<a href="https://example.pl">example.pl</a>"
//]
