Xml ProhibitDtd error

[agda.karlberg]

Hi,

I'm trying to validate an xml document against a schema. I get an
exception saying "For security reasons DTD is prohibited in this XML
document. To enable DTD processing set the ProhibitDtd property on
XmlReaderSettings to false and pass the settings into XmlReader.Create
method.", however I have set it to false so not sure what else to try.

Here's my code:

FileStream fs = File.Open(myFilePath, FileMode.Open);

XmlReaderSettings settings = new XmlReaderSettings();

settings.ProhibitDtd = false;
settings.Schemas.Add(null, "http://www.w3.org/TR/xmldsig-core/xmldsig-
core-schema.xsd");

settings.ValidationType = ValidationType.Schema;
settings.ValidationEventHandler += new
System.Xml.Schema.ValidationEventHandler(settings_ValidationEventHandler);

XmlReader reader = XmlReader.Create(fs, settings);

while (reader.Read())

Am I missing something obvious?

Many thanks,

AK

XmlReaderSettings settings = new XmlReaderSettings();

settings.ProhibitDtd = false;
settings.Schemas.Add(null, "http://www.w3.org/TR/xmldsig-core/xmldsig-
core-schema.xsd");

That schema has a DOCTYPE declaration so you need e.g.
XmlReaderSettings xrs = new XmlReaderSettings();
xrs.ProhibitDtd = false;
settings.Schemas.Add(null,
XmlReader.Create("http://www.w3.org/TR/xmldsig-core/xmldsig-core-schema.xsd",
xrs));

Works perfectly, thank you so much!
