Match patterns, search for a character larger than a character using regular expression

I need a regular expression so that when searching for ">" more.

, eg

for this line I will return - "if x> 2"

and for this line I will get false " <template>"

I tried this - [^<][a-zA-Z0-9_]+[a-zA-Z0-9_ ]*> as a regular expression but the problem is that it finds a substring that matches for example, in <template>it finds template>and returns true.

thank.

EDIT:

I use this regex [^<a-zA-Z0-9_][a-zA-Z0-9_]+[ ]*>, tried it all over the source code of firefox 1.0 and it seems to work fine.
