Thanks very much. This worked straight away. I was using
DOMNodeList* UrlList =
docElement->getElementsByTagName(XMLString::transcode("Url"));
DOMNode* Url = UrlList->item(0);
Which gave me Url but note the text node. I will need to learn much more
about xerces API.
Thanks very much Gareth, this was a great help.

Subject: RE: getNodeValue() doesn't work?
Hi,
take a look at the following code which is operating on your
XML.
DOMDocument *doc = parser->getDocument();
//the url element
DOMNode *Url =
doc->getDocumentElement()->getFirstChild()->getNextSibling();
//the text content
DOMNode *text = Url->getFirstChild();
cerr << "text node value: '" <<
XMLString::transcode(text->getNodeValue()) << "'" << endl;
//or using textContent
cerr << "text node value: '" <<
XMLString::transcode(Url->getTextContent()) << "'" << endl;
output:
text node value: 'url configuration'
text node value: '(null)'
unfortunately the second approach does not work as getTextContent has
not
yet been implemented (sorry, I forgot that).

When a document is parsed a tree of objects is created. An element has a
list of children of other nodes. In your case the only child of the Url
element is a text node with value "url configuration". You could also
have
other elements, comments etc.

The fact you are not validating has no bearing on the DOMNodes created
when parsing. When you say "of type" it is not referring to a schema
type.

All the navigation call I use above are in DOMNode. Take a look at the
examples - they are helpful.
