Passing and ID in Javascript

[venomdesign]

I need to pass a ID to a link. I was wondering if there was a way to do this.
here is my xml:
<?xml version=&quot;1.0&quot; ?>
- <PRODLIST>
<PROD MARKET_PRODUCT_ID=&quot;2454&quot; PRODUCT_TYPE_ID=&quot;1333&quot; ENGLISH_SHORT_DESC=&quot;US Gas FIN Swap DEC99 GD Tetco STX USD/MMBtu&quot; PRODUCT_STATUS_DESC=&quot;Active&quot; />
<PROD MARKET_PRODUCT_ID=&quot;2454&quot; PRODUCT_TYPE_ID=&quot;1333&quot; ENGLISH_SHORT_DESC=&quot;US Gas FIN Swap DEC99 GD Tetco STX USD/MMBtu&quot; PRODUCT_STATUS_DESC=&quot;Active&quot; />
</PRODLIST>

The PRODUCT_TYPE_ID will change depending on which PRODUCT you pick and it will append it within the XML, but I need to have something that will pass the PRODUCT_TYPE_ID so new data will be passed, in a html link, and not the same ID will be passed.
Can anyone help?
