get wrapping element using preg_match php

Question

I want a preg_match code that will detect a given string and get its wrapping element. I have a string and a html code like:

$string = \"My text\";
$html = \"<         


        

Answer 1

Even if regex is never the correct answer in the domain of dom parsing, I came out with another (quite simple) solution

<[^>/]+?>My String

if the html is good (ie it has closing tags, < is replaced with < & so on). This way you have in the first regex group the opening tag and in the second the closing one.
