正则表达式-需要从html注释获取字符串

Question

I need to get string from comment in HTML file, I was trying to do it with DOM, but I didn't find good solution with this method.

So I want to try it with regular expressions, but I can't find satisfactory solution. Please, can you help me?

This is what I need:

<!--adress-"String here I need to get"-->

Thanks in advance for answer

Answer 1

在此代码后查看$ matches

preg_match('~<!--adress-"(.*?)"-->~msi', $string, $matches);

Answer 2

HTML comments are regular; you can just match <!--adress-"([^">]+)"--> and get the first group.

This assumes that the comments are always well-formed and always have a quoted string containing no quotes.

Answer 3

It will be more accurate:

$regex = '<!--(.+?)-"{0,1}(.+?)"{0,1}-->';
preg_match_all($regex, $html, $matches_array);

Just do the var_dump($matches_array) and see results.
