i'm not sure i totally understand what you're after. if you want to grab the entire tag for each input field, just do something like this:
[code]
<?php
preg_match('|\<input.+?\>|i', $text, $matches);
echo "<pre>\n";
print_r($matches);
echo "</pre>\n";
?>
[/code]

if you're looking for more specific occurrences WITHIN those tags, it would take a bit more

thanks a lot, well, how would i find a submit button? I am trying to make this as flexible as possible because i am making my own proxy and i know that all websites code HTML a bit differently.

well, a submit button has to have a type="submit", so i would just search for the input tags and then check each one to see that type="submit"

That wouldnt work for every site because one site might have more inputs than another so...

you can't make it work for EVERY site, because some of them might be using a javascript button, some of them use malformed html, etc.

ya that is true but i would like it to work on most sites

probably not the best solution, but this will work:
[code]
preg_match_all('|\<input(.+?)\>|i', $content, $matches, PREG_PATTERN_ORDER);
foreach ($matches[1] as $match) {
  if (preg_match('|input\="submit"|i', $match)) {
    // it's a submit button, so do what you need
  }
}
[/code]

keep in mind that this only checks for "input="submit"", if you want to check for "input=submit" and input='submit'" as well, you'll have to modify the second check slightly.
