xml error: Non white space characters cannot be added to content
Solution 1
It looks like you're attempting to load an XML file into an XDocument, but to do so you need to call XDocument.Load("C:\\temp\\contacts.xml");
- you can't pass an XML file into the constructor.
You can also load a string of XML with XDocument.Parse(stringXml);
.
Change your first line to:
var doc = XDocument.Load("c:\\temp\\contacts.xml");
And it will work.
For reference, there are 4 overloads of the XDocument
constructor:
XDocument();
XDocument(Object[]);
XDocument(XDocument);
XDocument(XDeclaration, Object[]);
You might have been thinking of the third one (XDocument(XDocument)
), but to use that one you'd have to write:
var doc = new XDocument(XDocument.Load("c:\\temp\\contacts.xml"));
Which would be redundant when var doc = XDocument.Load("c:\\temp\\contacts.xml");
will suffice.
See XDocument Constructor for the gritty details.
Solution 2
Use XDocument.Parse(stringxml)

I am trying to open an xmldocument like this:
var doc = new XDocument("c:\\temp\\contacts.xml"); var reader = doc.CreateReader(); var namespaceManager = new XmlNamespaceManager(reader.NameTable); namespaceManager.AddNamespace("g", g.NamespaceName); var node = doc.XPathSelectElement("/Contacts/Contact/g:Name[text()='Patrick Hines']", namespaceManager); node.Value = "new name Richard"; doc.Save("c:\\temp\\newcontacts.xml");
I returns an error in the first line:
Non whitespace characters cannot be added to content.
The xmlfile looks like this:
<?xml version="1.0" encoding="utf-8"?> <Contacts xmlns:g="http://something.com"> <Contact> <g:Name>Patrick Hines</g:Name> <Phone>206-555-0144</Phone> <Address> <street>this street</street> </Address> </Contact> </Contacts>
