Big XML file

Hello,

I am constructing an XML database with a lot of records-the file has
about 3.7 Mb. When I try to search for records through JavaScript, I
have to load the file. It takes a long time over slow connections to do
it, and I need in fact only the smaller portion of it (the results of
the query). is there any way to do the search, avoiding the loading of
total file?

Thank you.

Bogdan

(1) Do the search on the server, sending only the results (seems
obvious). Send the query and receive the XML response using AJAX to
make the app look more responsive

(2) Set GZip encoding on the XML document returned - I've seen 4 meg
documents compressed to 250k using this technique, because the
repeating element tags are easily compressed (tokensed) by GZip.
All modern browsers support GZip encoded documents.
