在C＃中访问XML节点

Question

I'm trying to access nc:StructuredAddress where the preceding ecf:CaseParticipantRole = 'Debtor '. Not sure if there's always a trailing space or not since this is example XML so I need to accommodate for trailing whitespace. Subsequently, I'd also like to access the associated nc:LocationCityName, nc:LocationStateUsPostalServiceCode and nc:LocationPostalCode for that ecf:CaseParticipantRole.

I've tried using SelectNodes and using GetElementsByTagName with variations of starts-with(text()='Debtor ']". I'm not sure if I can even add more node names after the text() clause. Regardless... No luck with either. Any suggestions? I have very little exposure to XML so be gentle if I'm doing something idiotic.

Here's the XML.

And here's the C# code I have, tweaking the Name1 and Address sections in an attempt to get "something" to work.

        XmlDocument xmlNotice = new XmlDocument();
        XmlNamespaceManager xmlNameSpc = new XmlNamespaceManager(xmlNotice.NameTable);
        xmlNameSpc.AddNamespace("nc", "http://niem.gov/niem/niem-core/2.0");

Answer 1

Update: This will give you the list of StructuredAddress es:

XNamespace ecf = "urn:oasis:names:tc:legalxml-courtfiling:schema:xsd:CommonTypes-4.0";
XNamespace nc = "http://niem.gov/niem/niem-core/2.0";

var xml = XDocument.Load(@"C:\test.xml");

var y = xml.Descendants(ecf + "CaseParticipant").Where(p => p.Descendants(ecf + "CaseParticipantRoleCode").Any(c => c.Value.ToString().TrimEnd() == "Debtor"));
var x = y.Descendants(nc + "StructuredAddress");
