Identifying Unclosed HTML Tags (Needs Tweaking)

[jyushinx]

Hi,

 

I currently have code which searches a string for unclosed html tags. It works well except for one glitch. A tag like

<br/>

will be read as closed. But a tag such as

<br />

won't. Clearly there is something up with my regex, but I have no idea as I am clueless with it.

 

Here is the code for finding open tags

 

preg_match_all("#<([a-z]+)( .*)?(?!/)>#iU",$html,$result);

 

Any ideas as to how I can modify the regex to recognize tags as being closed like

<br />

 

Thanks.

Changing (?!/)> to (?<!/)> will enforce that a slash should not proceed the ending bracket.

 

P.S. You may want to trying running the content through tidy instead.
