Note that such isn't really the problem. Putting nearly anything after or before the .*? in a regex can cause you problems. Even just

    /<a href="(.*?)">/i

will match way too much by matching way too early against

    '<a href="oops" lots of stuff <a href="ok">'
    '<a href="oops" > d'oh! whitespace! <a href="ok">'
    '<a href="oops, break a browser? <a href="ok">'
