XmlReaderSettings.XmlResolver Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Sets the XmlResolver used to access external documents.

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


Public WriteOnly Property XmlResolver As XmlResolver
public XmlResolver XmlResolver { set; }

Property Value

Type: System.Xml.XmlResolver
An XmlResolver used to access external documents. If set to nulla null reference (Nothing in Visual Basic), an XmlException is thrown when the XmlReader tries to access an external resource.


For information on working with resolvers, see Working with XmlXapResolver, Working with XmlPreloadedResolver.


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(),

using (XmlReader reader = XmlReader.Create("HTMLPage.html", settings))
XDocument document = XDocument.Load(reader);
OutputTextBlock.Text = document.ToString();
