Usage example:
html_tags(html, “input”, “ir”);

echo “

print_r($nodes);
echo "

thank u very much friend!

$text = $link->textContents;

With the extract_tags() function, it’s also very simple :

$text = $link['contents'];

It was a bug in my regexp syntax. The “(?<name>…)” syntax that I used for marking named subgroups apparently only works in some versions of PHP and not others. I’ve rewritten the regexps to use the proper syntax – “(?P<name>…)”.
