Regex match for HTML tag containing "on" JS trigger
Answer
Answer
I want to check if an HTML tag (potentially split across multiple lines) contains an "on" JS trigger. The actual HTML tag and the Javascript are of no consequence. For example:
onblur="foo()"/>Other stuff
I've got most of this to work using the pattern:
<\w+([^>])+?(on\w+)+[\s\S]+?>
However, this also matches:
Other stuff
I modified the original pattern to:
<\w+([^>])+?(\s)+(on\w+)+[\s\S]+?>
but this matches only if the JS trigger keyword is preceded by 2 or more whitespace characters. A nudge in the right direction would be appreciated.
Answer
Might work <\w+(?=\s)[^>]*?\s(on\w+)[\s\S]+?>
