I am processing cXml orders and the xml begins with the following:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE cXML SYSTEM "http://xml.cxml.org/schemas/cXML/1.2.017/
cXML.dtd">

I am attempting to use the following code to transform the xml:

XslCompiledTransform transform = new XslCompiledTransform();
Stream resultStream = new MemoryStream();

XmlReader xslRdr = XmlReader.Create(new StringReader(xslSheet));

transform.Load(xslRdr);

XmlReaderSettings xRdrSettings = new XmlReaderSettings();
xRdrSettings.ProhibitDtd = false;
xRdrSettings.ValidationType = ValidationType.DTD;

XmlReader xmlRdr = XmlReader.Create(cxmlFilename, xRdrSettings);
transform.Transform(xmlRdr, null, resultStream);

My problem is that in my organization, my test machine cannot access
the url in the DOCTYPE without proxy authentication. I get this
exception when running the code:

"An error has occurred while opening external DTD 'http://xml.cxml.org/
schemas/cXML/1.2.017/cXML.dtd': The remote server returned an error:
(407) Proxy Authentication Required."

Can anyone point me to some examples of how to apply the proxy
authentication?

I attempted to create an XmlUriResolver with the proper proxy
credentials, and passed that into the XmlReaderSettings.XmlResolver
property, but that made no difference. I must be missing something
easy.

Any help would be appreciated.

Thanks,

Chris

I realize this is a few months after original post, but I pulled out a little hair on this too, so I thought I would go ahead and post the answer for other googlers.



I basically solved this by telling the xmlReader to ignore the dtd section by setting the xmlreadersettings.xmlresolver to nothing. Otherwise the parser will try to resolve the URL and you'll run into nasty proxy errors. Note xmlStream is your file



Dim settings As XmlReaderSettings = New XmlReaderSettings()

'ignore DocType or else the parser will try to resolve the dtd URI

'which will result in a Proxy 407 Authentication Required error

settings.XmlResolver = Nothing

settings.ProhibitDtd = False

Dim xml As New XmlDocument

Dim tr As XmlReader

tr = XmlReader.Create(xmlStream, settings)

xml.Load(tr)
