Need help on creating a parsing script...

[Joe-W]

Hi all, I have been trying to create a little script using PHP, that would filter a XML-formatted purchased order summary, to find out within that order summary file, which purchased order(s) contains a particular item, and that order(s) is going to be sent to a certain zip code.

However, after thinking a bit about my needs, I think using Javascript to create a client side script, will suit my needs better, but I am not that familiar with Javascript , thus I hope someone in this forum is kind enough to offer me some help.
--------------

As for the script,

1) It needs to take the XML-formatted order summary as an input, which within that XML file, there are multiple purchased orders.

2) It needs to find out which order contains a specific item, and if it does, whether or not that order is going to ship to a certain zip code.

3) Then it needs to output a XML file, which is a summary of those orders that fit the above criteria.

How difficult it is to write a script with Javascript to perform the above task? If anyone is kind enough to help out, please let me know via email. Thanks in advance!

So presumably this script is only going to be used by someone reviewing received orders (report generation, effectively), not a customer?

It's hard to say as you haven't provided the DTD, but it could be a lot of work to do from scratch. There may be existing code libraries that perform XML parsing implemented in ECMAScript/Javascript, but I know PHP has an XML parser.

There's also the question of data origin. That may affect how workable a client-side script may be. So in summary, it is possible, but you'll have to provide more information.
