* </order>

* If there is no "customer_id" element under "order_billing_info", then add it.
IF (loXml.HasChildWithTag("order_billing_info|customer_id") = 1) THEN
    ? "customer_id already exists, nothing to do..."
    RELEASE loXml
    CANCEL
ENDIF

* Add the customer_id element just before the "price_list" element.

* Get the "order_billing_info" element
loOrderBillingInfo = loXml.FindChild("order_billing_info")

* Call NewChildBefore to add an XML element <customer_id> before <price_list>
* First get the index of the element price_list
lnIndex = loOrderBillingInfo.TagIndex("price_list")
? "index = " + STR(lnIndex)

* Add the "customer_id" element just before specified index.
