Problem using NSXMLParser with NOAA data on iPhone

Question

Can anyone help me see why NSXMLParser is not causing these methods

parser:didStartElement:namespaceURI:qualifiedName:attributes:
parser:didEndElement:namespaceURI:qualifiedName:attributes:

to fire for the part of the following data:

<?xml version="1.0" encoding="ISO-8859-1"?><SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"&gt;&lt;SOAP-ENV:Body&gt;&lt;ns1:NDFDgenResponse xmlns:ns1=""><dwmlOut xsi:type="xsd:string"><?xml version="1.0"?>
<dwml version="1.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.nws.noaa.gov/forecasts/xml/DWMLgen/schema/DWML.xsd"&gt;

(body excluded)

</dwml>
</dwmlOut></ns1:NDFDgenResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>

I'm not an XML expert, but to me, the <dwml></dwml> part looks like just a regular element, to be parsed just like the parts before it.

I do get two parser:parseErrorOccurred: errors, #200 and #201, but they occur during the parsing of the <SOAP-ENV:Body> element, not the <dwml> element, so I'm not sure if they are relevant. Thanks for any help you can give me.

Update: A friend of mine has told me offline of several errors in the data above. I can't understand why NOAA would be sending out malformed XML though -- is there some secret to parsing it?

This is a SOAP web service, you might want to try this: http://code.google.com/p/wsdl2objc/
