jQuery Grid Plugin - jqGrid

Hi,
I want to write an example in my blog about using JQGrid with ASP.NET web service (the WS returns soap result, not json).
I managed to achieve this by using datatype: "xml" along with xmlReader. Although this works fine, i want to be sure that this is the recommended technique for consuming SOAP WS.

My WS return looks like the following:
<ArrayOfShipping>
<shipping>
<id>1</id>
<price>50000</price>
<customer>Sony</customer>
<destination>Brazil</destination>
</shipping>
−
<shipping>
<id>2</id>
<price>30000</price>
<customer>Amazon</customer>
<destination>Jordan</destination>
</shipping>
</ArrayOfShipping>

My xml reader definition is:
xmlReader:
    {
      root:"ArrayOfShipping",
      row:"shipping",
      page:"shippings>currentpage",
      total:"shippings>totalpages",
      records:"shippings>totalrecords",
      repeatitems:false,
      id:"id"
    }

Any objections or recommendations? Thanks.
