We are using WebDAV to extract and save Exchange users EML files off.  I
have run into a problem when I try and get a list of emails within a
folder.  We use the following…


strQuery = "<?xml version=\"1.0\"?><D:searchrequest xmlns:D = \"DAV:\" >"
+ "<D:sql>SELECT \"DAV:href\", \"DAV:contentclass\", \"urn:schemas:mailheader:message-id\" "
+ "FROM \"" + strRootURI + "\""
+ "WHERE \"DAV:ishidden\" = false AND \"DAV:isfolder\" = false"
+ "</D:sql></D:searchrequest>";


And from that we get the XMLNodeLists…


hrefNodes = ResponseXmlDoc.GetElementsByTagName("a:href");
ContentClassNodes = ResponseXmlDoc.GetElementsByTagName("a:contentclass");
MailHeaderMessageIDNodes = ResponseXmlDoc.GetElementsByTagName("d:message-id");

if(hrefNodes.Count > 0)
{
// Loop through the display name nodes.
     for(int i=0; i<hrefNodes.Count; i++)
     {
           string strClass = ContentClassNodes.Item(i).InnerText;
           string strURL = hrefNodes.Item(i).InnerText;
           string strMsgID = MailHeaderMessageIDNodes.Item(i).InnerText;

           // If this is a message save the EML off into the table
           if (strClass.CompareTo("urn:content-classes:message") == 0)
           {
                 SaveLetter(strURL, strMsgID, strUserName, strPassword,
                 strDomain, strServer, conn);
           }
     }
}

The problem is that the count for the hrefNodes always seems to be double
the other 2.  For example if I have 25 letters in a folder,
hrefNodes.Count is 50 and the other 2 show as 25.  Is there a reason for
this?

Thank You,
