System.Xml.Xsl.XslTransform supports the XSLT 1.0 syntax. The XSLT style sheet must include the namespace declaration xmlns:xsl= http://www.w3.org/1999/XSL/Transform.

This method loads the XSLT style sheet, including any style sheets referenced in xsl:include and xsl:import elements. External resources are resolved using an System.Xml.XmlUrlResolver with no user credentials. If the style sheet(s) are located on a network resource which requires authentication, use the overload that takes an System.Xml.XmlResolver as one of its arguments and specify an System.Xml.XmlResolver with the necessary credentials.

The style sheet is loaded from the current position of the System.Xml.XPath.XPathNavigator. To use just a portion of the loaded document as the style sheet, navigate to the node corresponding to the beginning of the style sheet. After the XslTransform.Load(System.Xml.XPath.XPathNavigator) method returns, the System.Xml.XPath.XPathNavigator is positioned at the beginning of the style sheet (on the xsl:style sheet node).

If the style sheet contains embedded scripting, the script is compiled to an assembly. The assembly has full trust. The recommended practice is to provide evidence using the XslTransform.Load(System.Xml.XPath.XPathNavigator, System.Xml.XmlResolver, System.Security.Policy.Evidence) method. For issues with the erload:System.Xml.Xsl.XslTransform.Load method and style sheets with embedded scripts, see article Q316755 in the Microsoft Knowledge Base at http://support.microsoft.com.
