Specific Info from XML Document

I'm trying to parse XML data and having a hard time doing it. Here is the XML part

<?xml version="1.0"?> <GetLowestOfferListingsForASINResponse xmlns="http://ift.tt/1iBZrs1"> <GetLowestOfferListingsForASINResult ASIN="b0091raue4" status="Success">   <AllOfferListingsConsidered>true</AllOfferListingsConsidered>   <Product xmlns="http://ift.tt/1iBZrs1" xmlns:ns2="http://ift.tt/1iBZq7r">

          <ShipsDomestically>True</ShipsDomestically>
          <ShippingTime>

          </Shipping>
        </Price>
        <MultipleOffersAtLowestPrice>False</MultipleOffersAtLowestPrice>
      </LowestOfferListing>

I want to loop through all of the "LowestOfferListing" nodes just return the "ItemCondition" and "Amount".

I have tried putting the data into an XML document, dataset, and datatable. Here is where i am at:

        Dim xml As New Xml.XmlDocument()
        xml.LoadXml(responseBody)
        Dim ds As New DataSet
        ds.ReadXml(New StringReader(responseBody))

Does anyone know how to loop through and retireve just these two values?
