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.
