I'm writing a CodeMirror extension for Brackets. To defineSimpleCodeMode I need to do some pattern matching and I'm trying to figure out how to achieve $subject.
e.g.
Match < of all the html tags
<body>
And ignore html tags which are followed by <%
<% if %>
Note: I only want to get the starting < of it
If some can help me out it would be a great help. Please do let me know if you need anymore details.
Thanks!

While this seems to be a bad idea, I can see two ways of doing it :
< followed by anything but the % character, then ignoring it(<)(?:[^%])
The [^] sequence allows you to search for anything but the following character.
The (?:) sequence is for non capturing groups.
<(?!%)
The (?!) sequence succeeds if it doesn't match the following character, but is not captured.
%>, you can just "reverse" the first option :(?:[^%])(>)
(careful here, the lookahead won't work as you need to go backwards)
(?<!%)>
