XslCompiledTransform.Load Method (String)

Loads and compiles the style sheet located at the specified URI.

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

public void Load(
	string stylesheetUri


Type: System.String

The URI of the style sheet.


The stylesheetUri value is null.


The style sheet contains an error.


The style sheet cannot be found.


The stylesheetUri value includes a filename or directory that cannot be found.


The stylesheetUri value cannot be resolved.


An error occurred while processing the request.


stylesheetUri is not a valid URI.


There was a parsing error loading the style sheet.

The XslCompiledTransform class supports the XSLT 1.0 syntax. The XSLT style sheet must use the namespace.

This method has the following behavior:

  • An XmlUrlResolver with no user credentials is used to resolve the style sheet URI, and process any xsl:import or xsl:include elements.

  • An XmlReader with default settings is used to load the style sheet. DTD processing is disabled on the XmlReader. If you require DTD processing, create an XmlReader with this feature enabled, and pass it to the Load method.

  • The document() function is disabled.

  • Embedded scripts are not supported.

You can use the Load(String, XsltSettings, XmlResolver) overload to specify an XmlResolver with the necessary authentication credentials, or to specify different XSLT settings.

The following example executes a transform and outputs to a file.

// Load the style sheet.
XslCompiledTransform xslt = new XslCompiledTransform();

// Execute the transform and output the results to a file.
xslt.Transform("books.xml", "books.html");
