Linq to XML querying an XDoc

我希望能够从span类访问文本，同时也能够获得span类之外的信息。例如：

这是我的XML文档信息示例：

    <item><title>Operations Applications - MDI Diagnostics</title><link>http://confidential-link.com</link>
<description><![CDATA[<div style="margin-top:5px"><link rel="stylesheet" type="text/css" href="confidential" />
<span class="srch-Icon"><a href="confidential" title="Operations Applications - MDI Diagnostics">
<img src="confidential" alt="Web Page" border="0" /></a></span>
<span class="psrch-Description"> THE INFORMATION I WANT</span>
<p class="srch-Metadata"><span class="srch-URL">
<a href="confidential" title="Operations Applications - MDI Diagnostics">confidential link</a>
        -
        66KB
          </span></p></div>]]></description>

<search:hithighlightedsummary> SIMILAR TO THE INFORMATION I WANT, COULD BE OPTION 2  </search:hithighlightedsummary>
</item>

这是我现在拥有的：

                var feeds = from feed in xdoc.Descendants("item")
                        select new RSSS
                        {
                            Site = "TOPS",
                            URL = url, 
                            Title = feed.Element("title").Value,
                            Link = feed.Element("link").Value,
                            Description = feed.Element("description").Value
                        };

按预期返回"描述"：

<div style="margin-top:5px"><link rel="stylesheet" type="text/css" href="confidential" />
<span class="srch-Icon"><a href="confidential" title="Operations Applications - MDI Diagnostics">
<img src="confidential" alt="Web Page" border="0" /></a></span>
<span class="psrch-Description"> THE INFORMATION I WANT</span>
<p class="srch-Metadata"><span class="srch-URL">
<a href="confidential" title="Operations Applications - MDI Diagnostics">confidential link</a>
        -
        66KB
          </span></p></div>

那么，我如何在仍然能够访问链接和标题等信息的情况下访问"span class=psrch Description"之间的信息呢？

**因为我不想找像这样的东西

var feeds = from feed in xDoc.Descendants("Show") where (string)feed.Attribute("Code") == "456" select new { EventDate = feed.Attribute("Date").Value };

这不允许我获得其他信息。

XDocument description = XDocument.Parse(feed.Element("description").Value);
