If the tag in question can't be nested (and assuming case insensitivity):

Regex regexObj = new Regex("<NAME>(?:(?!</NAME>).)*</NAME>", RegexOptions.Singleline | RegexOptions.IgnoreCase);

Be advised that this is a quick-and-dirty solution which might work fine for your needs, but might also blow up in your face (for example if tags occur within comments, if there is whitespace inside the tags, if there are any attributes inside the tags etc.). If any of these might be a problem for you, please edit your question with the exact specifications you need the regex to comply with.

Here is a regex which accepts any tag name: <(\w+)>.*?</\1>

\1 is back-referencing the group (\w+) and ensures that the closing tag must have the same name as the opening tag.

If you want to search for the special tag NAME then you could use this regex: <NAME>.*?</NAME>

This will match across several tags if they are on the same line. – Tim Pietzcker Feb 10 '11 at 08:18
Thanks. Now I have added the `?` to make the `*` non-greedy. – splash Feb 10 '11 at 08:23
