By that I mean you need to grab the substrings which precedes and
follows the text inside the quotation marks. If the input is
<input name="test{0}" size="40">
you'd want
<input name="
and
" size="40">
so that you can form the replacement <input name=" + DATA + "
size="40">.
Presumably you'd want 'test' and '0' as well for looking up the data.
