    Don't use regex to parse HTML. Here's why http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454 – Darin Dimitrov Mar 31 '10 at 11:15

Darin's comment is spot on -- don't use RegEx to parse HTML.

If, however, you have a very narrow requirement to find the word "class" immediately following a >, here's your pattern:

>class

There is a space at the end. If you need to capture "class" for replacement, surround it with parentheses ( ), then use the capture group \1.

This is not terribly robust, but is a start and is only applicable for a very narrow search requirement, not for any more involved parsing.

Sermons aside, it depends on what you can expect for sure, you can try with:

/[^y]class/
/\bclass/
/class abc/
