connect[connection string]{
table::sql{select product_id, name from products}]
$file[^file::create[text;export.xml;^untaint[xml]{<?xml version="1.0" encoding="$request:charset"?>
^{<product id="$products.product_id" name="$"/>}

   <product id="1" name="
Can be &quot;Quoted&quot;"/><product id="2" name="Johnson&amp;Johnson"/>
