}

my c# code is like this

XmlDocument doc = new XmlDocument();
doc.Load(@"xml\willowcreekassociationblog.wordpress.xml");
//Get Channel Node
XmlNode channelNode = doc.SelectSingleNode("rss/channel");
if (channelNode != null)
{
    //Add NameSpace
    XmlNamespaceManager nameSpace = new XmlNamespaceManager(doc.NameTable);
    nameSpace.AddNamespace("excerpt", "http://wordpress.org/export/1.2/excerpt/");
    nameSpace.AddNamespace("content", "http://purl.org/rss/1.0/modules/content/");
    nameSpace.AddNamespace("dc", "http://purl.org/dc/elements/1.1/");
    nameSpace.AddNamespace("wfw", "http://wellformedweb.org/CommentAPI/");
    nameSpace.AddNamespace("wp", "http://wordpress.org/export/1.2/");

    //Parse each item
    foreach (XmlNode itemNode in channelNode.SelectNodes("item"))
    {
        objrssItem.Add(rssItem);
        rssItem.GUID = itemNode.SelectSingleNode("guid").InnerText;
        rssItem.Title = itemNode.SelectSingleNode("title").InnerText;
        rssItem.dcCreator = itemNode.SelectSingleNode("dc:creator", nameSpace).InnerText;
        rssItem.Link = itemNode.SelectSingleNode("link").InnerText;
        rssItem.pubDate = DateTime.Parse(itemNode.SelectSingleNode("pubDate").InnerText);
        rssItem.ContentEncoded = itemNode.SelectSingleNode("content:encoded", nameSpace).InnerText;

        XmlNode cNode = doc.SelectSingleNode("rss/channel/item");
        foreach (XmlNode commentNode in cNode.SelectNodes("wp:comment", nameSpace))
        {
           //rssItem.Comments = Comments
            rsscomment.wpCmtId = Convert.ToInt32(commentNode.SelectSingleNode("wp:comment_id", nameSpace).InnerText);
            rsscomment.wpCmtAuthor = commentNode.SelectSingleNode("wp:comment_author", nameSpace).InnerText;
            rsscomment.wpCmtContent = commentNode.SelectSingleNode("wp:comment_content", nameSpace).InnerText;  
        }
    }
    oXMLListResult.listOfXMLResult = objrssItem;
}

i have xml like enter link description here

when I am trying to read for each item in channel with xmlnode and its working fine. and each item has multiple comments which trying to achieve by using foreach inside foreach. But wp:comment foreach item its not working. What am i doing wrong? I did some google but no luck.

Thanks.

XmlNode cNode = doc.SelectSingleNode("rss/channel/item");

This is resetting your item enumeration to the beginning, which would cause every item to have identical comments.

EDIT:
I believe this is the easiest way to fix the problem I mentioned. By searching below the already selected node, you avoid the repetition. Note that cNode is no longer required.

foreach (XmlNode commentNode in itemNode.SelectNodes("wp:comment", nameSpace))
