Combining two XML search functions in javascipt

Ok I have a movie site with an xml database of SEPARATE xml files, one for each letter of the alphabet. With much grief and time I finally managed to adapt code to work with my files to search all at the same time but it only matches EXACT data matches.

this is what i have already:
http://www.gre.ac.uk/~tk301/3dmm/search.html

Now this was all well and good and I was pleased until I saw this second html page which does the same search but matches ANY string, this would be perfect for my site, but combining the code into my existing search is proving difficult.

this is the code i'd like to use some of:
http://www.gre.ac.uk/~tk301/3dmm/xmlsearch.html

the second one is not formatted how i would like and the results come out in a select bos which i don't want, all i need is to put the any string code into my original page, but i've tried and failed everytime

Can anyone help me?
