Re: regex is hanging inside loop, neither going

[atcroft]

Your code hangs in the getEleMul subroutine when $i hits 32, which appears to be at or around the time it hits the end of the particular <div> you are in. The regex in the while() loop continues to attempt to match $_[1], which is where I believe your headache comes in. (Mine was in trying to read that complicated regex.) I suspect it is the backtracking you are asking the regex engine to do to find another match that is the cause of your issue.

You might consider dropping in Regexp::Debugger to help debug why the regex issue is occurring.

Hope that helps.
