XslCompiledTransform.Load Method (String)

.NET Framework 4.5

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
)

Parameters

stylesheetUri: Type: System.String
The URI of the style sheet.

Exceptions

Exception	Condition
ArgumentNullException	The stylesheetUri value is null.
XsltException	The style sheet contains an error.
FileNotFoundException	The style sheet cannot be found.
DirectoryNotFoundException	The stylesheetUri value includes a filename or directory that cannot be found.
WebException	The stylesheetUri value cannot be resolved. -or- An error occurred while processing the request.
UriFormatException	stylesheetUri is not a valid URI.
XmlException	There was a parsing error loading the style sheet.

Remarks

The XslCompiledTransform class supports the XSLT 1.0 syntax. The XSLT style sheet must use the http://www.w3.org/1999/XSL/Transform 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.

Examples

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

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

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