alright, jer. let's see what we can do...
here's an eyeballed attempt:
<(select\s?[^>].*?)|(input\s[^t]*?type\s*?=\s?('|"|\s)(hidden|text|submit)\3[^>].*?)>
to keep it easier, i'd think about using that to get your general matches.
iterating through those, i'd apply another regex to break out the name,
type, and value. you could very well catch it all in the above, however,
it's not as straightforward and hence, not easily maintained. if you need
additional help on writing this, let me know. i'll psuedo-code the whole
enchillada if you want. this should be sufficient in getting only those tags
you listed above...which is a good start.
btw, make the seach caseINsensitive.
