Download "The Regex Coach" and play with that -- It's not 100% the
same as PHP, and the escaping of backslashes for PHP isn't in it, but
it rocks for visual presentation of pattern/match
Your main problem is a lack of start/end delimiters for the pattern:
'|<h1[^>]*>(.*)</h1>|ims'
would probably be better.
| at beginning/end as pattern delimiters
i becase H1 and h1 are both the same tag in HTML
ms because newlines inside the text are okay
Take out the \b because I dunno what it does, but you don't need it.
.*? is kinda silly -- .* mean "0 or more characters", and ? means
"maybe" but putting them together has no added value, so lose the ?
