<div class="1">
    <p>blah blah blah</p>
    <div class="1.1">
        trolololol
    </div>

Regexp are not that intelligent to count how many tags you have opened and need to be closed before stopping the match. It stops at the first occurence of </div>. Try to use a real html parser if you want to access tags as real tags and not strings.

Regular expressions should not be used to parse documents like XML, HTML, "BBCode", JSON... You should look for a real DOM parser, for example PHP's DOM extension
