代码：

...
XName entry = XName.Get("entry", "http://www.w3.org/2005/Atom");
XName content = XName.Get("content", "http://www.w3.org/2005/Atom");
XName properties2 = XName.Get("properties", "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata");
XName srl = XName.Get("TheUrl", "http://schemas.microsoft.com/ado/2007/08/dataservices");
XName title2 = XName.Get("Title", "http://schemas.microsoft.com/ado/2007/08/dataservices");
XName tag = XName.Get("Tag", "http://schemas.microsoft.com/ado/2007/08/dataservices");
XName journ = XName.Get("journ", "http://schemas.microsoft.com/ado/2007/08/dataservices");
var result2 = theResult.Descendants(content).Descendants(properties2)
    .Select(en => new {
        srl = en.Element(srl)
        , title2 = en.Element(title2)
        , tag = en.Element(tag)
        , journ = en.Element(journ)
    });
...

result2给出以下内容：

0: { srl = {<d:TheUrl>/Lists/ListText/Attachments/1/animation-1.gif</d:TheUrl>}, title2 = null, tag = null, journ = null}
1: { srl = null, title2 = {<d:Title>This is title 1</d:Title>}, tag = {<d:Tag>This is Tag1</d:Tag>}, journ = null}
2: { srl = null, title2 = {<d:Title>New Attachment</d:Title>}, tag = null, journ = null}
3: { srl = null, title2 = {<d:Title>This is title 2</d:Title>}, tag = {<d:Tag>This is summary tag</d:Tag>}, journ = {<d:FullJournal>&amp;lt;div class="ExternalClassCB0921E6581F4789A9SDSDF234F2C1BC29E6B"&amp;gt;&amp;lt;p&amp;gt;This is a sample Article which may have &amp;lt;strong&amp;gt;BOLD&amp;lt;/strong&amp;gt;&amp;lt;/div&amp;gt;</d:FullJournal>}}

如您所见，它将每个entry拆分为两个单独的索引。

如何制作，以便它通过每个主要entry节点（<entry m:etag="&quot;1&quot;">）并从TheUrl节点向我<m:inline>提供，并告诉我{ {1}}来自每个索引的Title, Tag, FullJourn节点？

因此，<m:properties>将成为每result2个索引，如下所示：

试试这个

       XName entry = XName.Get("entry", "http://www.w3.org/2005/Atom");
        XName content = XName.Get("content", "http://www.w3.org/2005/Atom");
        XName properties2 = XName.Get("properties", "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata");
        XName srl = XName.Get("TheUrl", "http://schemas.microsoft.com/ado/2007/08/dataservices");
        XName title2 = XName.Get("Title", "http://schemas.microsoft.com/ado/2007/08/dataservices");
        XName tag = XName.Get("Tag", "http://schemas.microsoft.com/ado/2007/08/dataservices");
        XName journ = XName.Get("FullJournal", "http://schemas.microsoft.com/ado/2007/08/dataservices");
        XName etag = XName.Get("etag", "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata");

        var result2 = theResult.Descendants(entry).Where(en => en.HasAttributes).Select(en => new
        {
            srl = en.Descendants(srl).FirstOrDefault(),

            title2 = en.Descendants(title2).FirstOrDefault()
            ,
            tag = en.Descendants(tag).FirstOrDefault()
            ,
            journ = en.Descendants(journ).FirstOrDefault()

        });
