如何使用Xdocument將xml元素值獲取為字符串

Question

我將XML存儲在字符串中，並使用Xdocument將字符串從xml解析為我需要獲取xml元素值，並使用該值將其插入db中。 任何幫助，將不勝感激。

XML：

<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">
- <ListInventorySupplyResult>
- <InventorySupplyList>
- <member>
  <SellerSKU>043859634910</SellerSKU> 
  <FNSKU>X000IA4045</FNSKU> 
  <ASIN>B005YV4DJO</ASIN> 
  <Condition>NewItem</Condition> 
  <TotalSupplyQuantity>10</TotalSupplyQuantity> 
  <InStockSupplyQuantity>10</InStockSupplyQuantity> 
- <EarliestAvailability>
  <TimepointType>Immediately</TimepointType> 
  </EarliestAvailability>
  <SupplyDetail /> 
  </member>
  </InventorySupplyList>
  </ListInventorySupplyResult>
- <ResponseMetadata>
  <RequestId>d50af29d-f203-4efc-a864-1725a59ded97</RequestId> 
  </ResponseMetadata>
  </ListInventorySupplyResponse>

碼：

XDocument xd = XDocument.Parse(a);
string Sku = xd.Element();
var ASIN = xd.Descendants("ASIN");
var Condition = xd.Descendants("Condition");
var TotalSupplyQuantity = xd.Descendants("TotalSupplyQuantity");

Answer 1

您應該使用xml名稱空間http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/

var xDoc = XDocument.Parse(xml);
XNamespace ns = "http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/";

var condition = (string)xDoc.Descendants(ns + "Condition").First();

要么

您可以在任何 xml命名空間中搜索Tag 條件

var condition2 = (string)xDoc.Descendants()
                             .First(d => d.Name.LocalName == "Condition");

---

要么

您可以使用XPath在任何 xml名稱空間中獲取Condition

var condition3 = (string)xDoc.XPathSelectElement("//*[local-name()='Condition']");

Answer 2

用這個：

string value = xd.Root.Element("SellerSKU").Value;
