Re: Extract a string from the line

What LanX said. Do not do it with regex.

Your regex is wrong (besides what LanX noted) in that it is extremely unsafe and misses some restrictions.

my @numbers = m{
    <stlib:membit       # Opening tag
    [^.]*               # Optional attributes
    >                   # End of opening tag
    \s*                 # Optional whitespace
    ([0-9]+)            # The number you want
    \s*                 # Optional whitespace
    </stlib:membit>     # Closing tag
    }gx;                # I want all of them in this line

> What LanX said. Do not do it with regex. Yeah, but for clarification, I said "in most cases". :) Sometimes the XML is just so static and restricted that using a full parser would be overkill. `pdftohtml -xml` is one example for that. PS: if you want to allow optional whitespace, you might also want to add an `/s` modifier to match newlines too.
