[iPhone sdk] DOM/create XML support?

Question

Is there any way to create arbitrary XML on the iPhone other than the low-tech solution of using strings?
Most environments I've worked in have support for building up a document, i.e.
document doc = new document(root);
addElement("myelem1").setText("sometext1");
addElement("myelem2").setText("sometext2");
mystring = doc.asXml();
You get the idea. The underlying API handles all the tag generation, entity replacement, etc. Is this available in the iPhone SDK somewhere?
Thanks in advance.

Google has written an almost drop in replacement of NSXMLDocument. I say almost because initWithContentsOfURL is not implemented, nor is -nodesForXPath:error. There may be others that are missing, but it worked for me once I initialized it with an NSString instead of a URL. This replacement is part of the Google Data API. There are only 3 classes that need to be imported out of the whole library. You will also need to add libxml2 to the Frameworks and update your build headers.

The XML replacement is only in SVN for the moment, see http://code.google.com/p/gdata-objectivec-client/source/checkout to get it.
