XmlReaderSettings.DtdProcessing Property

Gets or sets the DtdProcessing enumeration.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

'Declaration
Public Property DtdProcessing As DtdProcessing

Property Value

Type: System.Xml.DtdProcessing
The DtdProcessing enumeration.

The DtdProcessing enumeration contains the Prohibit, Ignore, and Parse enumerators. Prohibit is the default behavior. This enumeration is set on the DtdProcessing property. In the .NET Framework for Silverlight, the DtdProcessing property replaces the ProhibitDTD property and adds the ability to ignore the DOCTYPE element.

Important noteImportant Note:

If the DtdProcessing property is set to DtdProcessing.Ignore, the XmlReader will not report the DTDs. This means that the DTD/DOCTYPE will be lost on output.

The following example preloads the DTDs and entities defined in XHTML 1.0 by setting Xhtml10 on the XmlPreloadedResolver. In this example, the XHTMLPage.html file is a part of the application's XAP package; therefore, we have to pass a fallback resolver to the constructor of the XmlPreloadedResolver.


Dim settings As XmlReaderSettings = New XmlReaderSettings()
settings.XmlResolver = New XmlPreloadedResolver(New XmlXapResolver(), XmlKnownDtds.Xhtml10)
Using reader As XmlReader = XmlReader.Create("HTMLPage.html", settings)
    Dim document As XDocument = XDocument.Load(reader)
    OutputTextBlock.Text = document.ToString()
End Using
