如何使用LINQ to XML来得到这个属性？ [英] How to get this attribute using linq to xml?

问题描述

我有以下的XML：

 ＆LT;结果ID =1，新的xmlns =htt​​p://schemas.microsoft.com/sharepoint/soap/＆GT;
    ＆LT;错误code取代; 00000000＆LT; /错误code取代;
    ＆LT; ID /＆GT;
    ＆LT; Z：排ows_ID =6/＆GT;
＆LT; /结果＆GT;
 

我一直在尝试使用以下方法来获取 ows_ID 值：

 的XNamespace NS =htt​​p://schemas.microsoft.com/sharepoint/soap/;
字符串NEWID =（来自R在resDoc.Descendants（NS +行）
               选择（串）r.Attribute（ows_ID））第一（）。
 

不返回任何记录，并且：

 的XNamespace NS =htt​​p://schemas.microsoft.com/sharepoint/soap/;
字符串NEWID =（来自R在resDoc.Descendants（NS +Z：排）
               选择（串）r.Attribute（ows_ID））第一（）。
 

这将引发从一个错误的：

什么是正确的方式，我得到这个值？

更新 - 完成 Z：行节点

解决方案

  VAR NS = XNamespace.Get（＃RowsetSchema）;
    VAR ID = XML
      .Descendants（NS +行）
      。选择（行=＆GT; row.Attribute（ows_ID）值。）
      。第一（）;
 

或

  VAR NS = XNamespace.Get（＃RowsetSchema）;
    VAR ID = XML
      .Descendants（NS +行）
      。第一（）
      属性约（ows_ID）
      。值;
 

I have the following XML:

<Result ID="1,New" xmlns="http://schemas.microsoft.com/sharepoint/soap/">
    <ErrorCode>0x00000000</ErrorCode>
    <ID />
    <z:row ows_ID="6" />
</Result>

I have been trying to get the ows_ID value using the following methods:

XNamespace ns = "http://schemas.microsoft.com/sharepoint/soap/";
string newId = (from r in resDoc.Descendants(ns + "row")
               select (string)r.Attribute("ows_ID")).First();

which returns no records, and:

XNamespace ns = "http://schemas.microsoft.com/sharepoint/soap/";
string newId = (from r in resDoc.Descendants(ns + "z:row")
               select (string)r.Attribute("ows_ID")).First();

which throws an error from the :

What is the proper way for me to get this value?

UPDATE - Complete z:row node

<z:row ows_ContentTypeId="0x010090ADDB8ED990B741A07020AB204CDB880100311975766C6F0E4CBE4EBFBC3CBFD9AB" ows_Title="test 2 attachments343434" ows_AggregateDesc="&lt;div class=&quot;ExternalClass05363FABD7BB400483A6AE4BB3B9B6CE&quot;&gt;&lt;p&gt;yes?&lt;/p&gt;&lt;/div&gt;" ows_Remarks="&lt;div class=&quot;ExternalClassB63AA0BFC1804E24B10C9559D7FBEBA5&quot;&gt;&lt;p&gt;no?&lt;/p&gt;&lt;/div&gt;" ows_PublishDate="2012-06-15 12:00:00" ows_MemoStatus="Submitted" ows_ID="6" ows_ContentType="FridayMemo" ows_Modified="2012-06-27 14:00:47" ows_Created="2012-06-27 14:00:47" ows_Author="49;#Abe Miessler" ows_Editor="49;#Abe Miessler" ows_owshiddenversion="1" ows_WorkflowVersion="1" ows__UIVersion="512" ows__UIVersionString="1.0" ows_Attachments="0" ows__ModerationStatus="0" ows_LinkTitleNoMenu="test 2 attachments343434" ows_LinkTitle="test 2 attachments343434" ows_LinkTitle2="test 2 attachments343434" ows_SelectTitle="6" ows_Order="600.000000000000" ows_GUID="{393F36F5-FFA8-4F6E-A12A-1107AA713F25}" ows_FileRef="6;#nc/ceo/Lists/FridayMemo/6_.000" ows_FileDirRef="6;#nc/ceo/Lists/FridayMemo" ows_Last_x0020_Modified="6;#2012-06-27 14:00:47" ows_Created_x0020_Date="6;#2012-06-27 14:00:47" ows_FSObjType="6;#0" ows_SortBehavior="6;#0" ows_PermMask="0x7fffffffffffffff" ows_FileLeafRef="6;#6_.000" ows_UniqueId="6;#{F4C6B345-4590-4791-9384-18983132F055}" ows_ProgId="6;#" ows_ScopeId="6;#{8450C4BD-0866-40ED-A0CD-22E3105E0845}" ows__EditMenuTableStart="6_.000" ows__EditMenuTableStart2="6" ows__EditMenuTableEnd="6" ows_LinkFilenameNoMenu="6_.000" ows_LinkFilename="6_.000" ows_LinkFilename2="6_.000" ows_ServerUrl="/nc/ceo/Lists/FridayMemo/6_.000" ows_EncodedAbsUrl="http://sptestmnc.nevcounty.net/nc/ceo/Lists/FridayMemo/6_.000" ows_BaseName="6_" ows_MetaInfo="6;#" ows__Level="1" ows__IsCurrentVersion="1" ows_ItemChildCount="6;#0" ows_FolderChildCount="6;#0"

解决方案

    var ns = XNamespace.Get("#RowsetSchema");
    var id = xml
      .Descendants(ns + "row")
      .Select(row => row.Attribute("ows_ID").Value)
      .First();

or

    var ns = XNamespace.Get("#RowsetSchema");
    var id = xml
      .Descendants(ns + "row")
      .First()
      .Attribute("ows_ID")
      .Value;
