The second one was at the end of the expression - if it had matched the zero
width alternative then the overall match would have been shorter.

Here's another alternative expression that I think does what you want:

  const char* badPatternStr  = "<input[^>]*name=\"?([^>
\"]*)\"?[[:space:]][^>]*value=\"?([^> \"]+)";

Note the extra \"?[[:space:]] after the matched text - I think that will
work, there does have to be one or more spaces between attributes doesn't
there?
