Specifies the options for processing DTDs. The DtdProcessing enumeration is used by XmlReaderSettings.
Namespace: System.Xml
Assembly: System.Xml (in System.Xml.dll)
Public Enumeration DtdProcessing
public enum DtdProcessing
| Member name | Description | |
|---|---|---|
|
Prohibit | Specifies that when a DTD is encountered, an XmlException is thrown with a message that states that DTDs are prohibited. This is the default behavior. |
|
|
Ignore | Causes the DOCTYPE element to be ignored. No DTD processing occurs. Warning: The DTD/DOCTYPE will be lost on output. |
|
|
Parse | Is used for parsing DTDs. |
This enumeration is set on the DtdProcessing property. In .NET Framework for Silverlight, the DtdProcessing property replaces the ProhibitDTD property in .NET Framework and adds the ability to ignore the DOCTYPE element.
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
XmlReaderSettings settings = new XmlReaderSettings(); settings.DtdProcessing = DtdProcessing.Parse; settings.XmlResolver = new XmlPreloadedResolver(new XmlXapResolver(), XmlKnownDtds.Xhtml10); using (XmlReader reader = XmlReader.Create("HTMLPage.html", settings)) { XDocument document = XDocument.Load(reader); OutputTextBlock.Text = document.ToString(); }
