I have an XML document loaded from an RSS feed and I want to pick the exchange rate value shown in the dc:value node.

The value should simply be displayed in  Label1.text.

I have been able to read all 23 items from the "item" node but can't seem to get the value from the child nodes. Anyone able to see the problem with this code and the fix for it. I attach the xml document as well.

Please help!
man.AddNamespace("rdf", "http://www.w3.org/1999/02/22-rdf-syntax-ns#");
                man.AddNamespace("slash", "http://purl.org/rss/1.0/modules/slash/");
                man.AddNamespace("taxo", "http://purl.org/rss/1.0/modules/taxonomy/");
                man.AddNamespace("dc", "http://purl.org/dc/elements/1.1/");
                man.AddNamespace("syn", "http://purl.org/rss/1.0/modules/syndication/");
                man.AddNamespace("admin", "http://webns.net/mvcb/");
                man.AddNamespace("feedburner", "http://rssnamespace.org/feedburner/ext/1.0");
                man.AddNamespace("rss", "http://purl.org/rss/1.0/");

                XmlNodeList xnList = responseXML.SelectNodes("rdf:RDF//rss:item", man);

                bool found = false;
                foreach (XmlNode xn in xnList)
                {
                    XmlNode currencyCODE = xn.SelectSingleNode("descendant::dc:baseCurrency", man);
                    found = (currencyCODE != null) ? true : false;
                    if (found)
                    {
                        if (currencyCODE.InnerText == "AUD")
                        {
                            XmlNode currencyVALUE = xn.SelectSingleNode("descendant::dc:value", man);
                            if (currencyVALUE != null)
                                Label1.Text = currencyVALUE.InnerText;
                        }
                        break;
                    }
                }

you need to add a namespace

xmlns:cb="http://www.cbwiki.net/wiki/index.php/Specification_1.2/"

                man.AddNamespace("cb", "http://www.cbwiki.net/wiki/index.php/Specification_1.2/");

both value and baseCurrency are NOT in dc: but in cb:
