the error message says "can't have : in name"

the soap: namespace prefix, have handle differently when building xelement - can't put "soap:element name" in there.

you can use xnamespace set xmlns namespace, , prepend element name. use xattribute set namespace prefix.

try this:

xnamespace soap = "http://www.w3.org/2003/05/soap-envelope"; xelement msg3 = new xelement(soap + @"envelope",                     new xattribute(xnamespace.xmlns + "soap", "http://www.w3.org/2003/05/soap-envelope"),                       str in source                       let fields = str.split(',')                       select new xelement(soap + @"body", 

this give you

<soap:envelope xmlns=http://www.w3.org/2003/05/soap-envelope>   <soap:body>   </soap:body> </soap:envelope> 

added

to add xml declaration can switch xelement xdocument , use xdeclaration property:

xnamespace soap = "http://www.w3.org/2003/05/soap-envelope"; xdocument msg3 = new xdocument("1.0", "utf-8", "yes"),                    new xelement(soap + @"envelope",                       new xattribute(xnamespace.xmlns + "soap", "http://www.w3.org/2003/05/soap-envelope"),                         str in source                         let fields = str.split(',')                         select new xelement(soap + @"body", 

this give xdocument xml declaration this:

<?xml version="1.0" encoding="utf-8" standalone="yes"?> 

if @ in debugger, may not see xml declaration if @ xdeclaration property in debugger or save file (via save(string filename) method will.
