XDocument Parse- Element("ServiceResponse").Element("Message").Value returns null

Question

4.50/5 (2 votes)

See more:

XML

<?xml version="1.0" encoding="utf-8" ?>
<ServiceResponse xmlns:xsd="http://www.w3.org/"
xmlns:xsi="http://www.w3.org/"
xmlns="http://www.dealerlink.us/"><Response>REJECTED</Response>
<Message>ZIP OUT OF AREA</Message>
</ServiceResponse>

I have XML as above, I want value "ZIP OUT OF AREA" in string "msg"

For that I wrote a code as below:

C#

XDocument XDOC = XDocument.Parse(xmlstring);
string msg=XDOC.Element("ServiceResponse").Element("Message").Value;

but string returns null.

Please help, I am stuck at this point.
thanks.

Solution 1

You're running into problems because you're trying to read elements in a namespace without specifying that namespace.

The last attribute of the XML, xmlns="http://www.dealerlink.us" defines the default namespace of the document as http://www.dealerlink.us.

You can fix that by prefixing your element names with the namespace like this:

C#

string xmlstring = "<?xml version=\"1.0\" encoding=\"utf-8\" ?><ServiceResponse xmlns:xsd=\"http://www.w3.org/\" xmlns:xsi=\"http://www.w3.org/\" xmlns=\"http://www.dealerlink.us/\"><Response>REJECTED</Response><Message>ZIP OUT OF AREA</Message></ServiceResponse>";

XNamespace ns = "http://www.dealerlink.us/";
XDocument XDOC = XDocument.Parse(xmlstring);

string msg = XDOC.Element(ns + "ServiceResponse").Element(ns + "Message").Value;

Hope this helps,
