The XPath expression /*
would match the document element, but it would be simpler just to use the rootElement
property of xmlDocument
to get this element directly without using XPath.

Question
I need to get the name of the first element in an XML document, e.g. the string "TitleName" of the XML snippet (which is the first line of an XML document):
<TitleName Major="1" Minor="0" Revision="1">
What XPath
command (XPathRootName
in the code snippet below) would I need to specify for this NSXMLDocument
in order to get the string "TitleName"?
NSData *xmlData = [xmlStr dataUsingEncoding:NSUTF8StringEncoding];
NSError *error;
NSXMLDocument *xmlDocument = [[NSXMLDocument alloc]initWithData:xmlData
options:0 error:&error];
NSXMLElement *rootNameXMLElement = [[xmlDocument
nodesForXPath:XPathRootName error:&error] lastObject];;
NSString *rootName = rootNameXMLElement.stringValue;
