     </content> 
    </entry> 
    //..more entry 
</feed> 

code:

... 
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 donne les indications suivantes:

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>}} 

Comme vous pouvez le voir il divise chaque entry en deux index distincts.

Comment puis-je le faire de sorte que, il passe par chaque nœud entry primaire (<entry m:etag="&amp;quot;1&amp;quot;">) et me donne TheUrl du nœud <m:inline>, et me donne Title, Tag, FullJourn de noeud <m:properties> par index?

Alors result2 deviendrait un indice par entry comme ce qui suit:

0: { srl = {<d:TheUrl>/Lists/ListText/Attachments/1/animation-1.gif</d:TheUrl>}, 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>This is title 2</d:Title>}, tag = {<d:Tag>This is Tag2</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>}}
