I use virtuemart 2.0.14 joomla 2.5.14 and csv improved free version 5.11
I want to make a simple xml for price comparison sites. My problem is how can I set the fields and the xml start and close lines. This is an examlpe xml:
<?xml version="1.0" encoding="UTF-8" ?>
<products>
   <product>
      <manufacturer>Samsung</manufacturer>
                <category>Computer > Monitor</category>
      <name>SyncMaster 913N</name>
       <price>91125</price>
      <product_url>http://www.example.com/products.php?id=12554</product_url>
   </product>
   ...
</products>
