Regular Expression for tags

I need to write regular expression that will match any pair of tags <(.*?)>.*?</\1> but only if there is no other pair tags between them. Tag names are variable length.

You can easily exclude nested tags by excluding the angle bracket needed to open them:

<([^<>]+)>[^<]*</\1>

This regex won't work if the opening tag has attributes. If you want to allow those, try this:

<(\S+)[^<>]*>[^<]*</\1>

You simply should not do this with regex. However, don't take my word for it.

So long as you maintain the "Only if there is no other tags between them" this is easy. 

<\s*([^>]+?)\s*>[^<]*</\s*\1\s*>
