Question

I have a rather complex XML document

<ItemSearchResponse xmlns="-------">
  <OperationRequest>
    <HTTPHeaders>
    </HTTPHeaders>
    <RequestId>0S57WGDPNC7T8HNBV76K</RequestId>
    <Arguments>
    </Arguments>
    <RequestProcessingTime>0.441776990890503</RequestProcessingTime>
  </OperationRequest>
  <Items>
    <Request>
      <ItemSearchRequest>
      </ItemSearchRequest>
    </Request>
    <TotalResults>1020</TotalResults>
    <TotalPages>102</TotalPages>
    <Item>
      <ASIN>B004WL0L9S</ASIN>
      <SalesRank>1</SalesRank>
      <ItemAttributes>
         <Manufacturer>Georgia Pacific Consumer Products LP (Cut-Sheet Paper)</Manufacturer>
         <Title>GP Copy &amp; Print Paper, 8.5 x 11 Inches Letter Size, 92 Bright White, 20    Lb, Ream of 500 Sheets (998067R)</Title>
      <ItemAttributes>
    </Item>
  <Items>

I run this query over it and it returns of list of zero:

XDocument doc = XDocument.Load(url);
List<Item> Items = (from c in doc.Elements("Item")
          select new Item
          {
            Title = c.Element("Title").Value
            SaleRank = c.Element("SaleRank").Value
            ASIN = c.Element("ASIN").Value
           }).ToList<Item>();

I am really new to XLinq but according to the documentation that should work.

Answer 1

Turns out I need to add the namespace to query.

XNamespace ns = NAMESPACE;

var items = (from c in doc.Descendants(ns +"Item")
    select new Item
    {
       Title = c.Element(ns + "ItemAttributes").Element(ns + "Title").Value,
       SalesRank = c.Element(ns +"SalesRank").Value,
       ASIN = c.Element(ns + "ASIN").Value
    }).ToList<Item>();
