It's explained on
http://www.ismods.com/wiki/index.php/ISXEQ2:vendor_%28Data_Type%29 (I even used price in the example).
Basically you would do this if you knew the name of the item:
Code:
echo ${Vendor.Item[candle].Price}
Or, if you wanted to index through them, you could use numbers instead. For brokers, 8 is always the maximum number possible; however, you should use ${Vendor.NumItemsForSale} to get the proper "max" number.
So, to see the price of the 3rd item on the search page:
Code:
echo ${Vendor.Item[3].Price}
Couple other notes:
1. You can search the broker using the isxeq2 Broker command:

2. Once you've searched, you can navigate search pages using the "GotoSearchPage" method of the vendor datatype ( ie, Vendor:GotoSearchPage[${Vendor.CurrentSearchPage}+1] )
3. Other useful vendor members while searching the broker:
Code:
${Vendor.CurrentSearchPage}
${Vendor.TotalSearchPages}
