regular expression check for closing tag XHTML

Question

The end of my expression is the only part causing me problems, im trying to match > not />

something like this: \s*[^\/]> however i dont want to match any other characters before the >

Here is an example, I want this to match any img tags that are not closed.

<img((\s+\w+(\s*=\s*(?:".*?"|'.*?'|[^'">\s]+))?)+\s*|\s*)\s*[^\/]>

Answer 1

Just get rid of the [^\/] at the end, since you only want to match on the >, and no other character:

<img((\s+\w+(\s*=\s*(?:".*?"|'.*?'|[^'">\s]+))?)+\s*|\s*)\s*>

Answer 2

'(<img.*?(?<=[^/])>)'

positive look-behind checks only for preceding characters. As I understand you only need to check if > is not preceded by \.

As bdukes points out, negative look-behind is another option: (<img.*?(?<!/)>)
