Remarks

Note

There are differences between XSLT compiled in Debug mode and XSLT compiled in Release mode. In some situations, style sheets compiled in Debug mode will not throw errors during Load, but will later fail during Transform. The same style sheet compiled in Release mode will fail during Load. An example of such behavior is when a variable that is not of a node-set type is assigned to an expression where a node-set is required.

Transform(XmlReader, XsltArgumentList, TextWriter)

Source:: XslCompiledTransform.cs

Source:: XslCompiledTransform.cs

Source:: XslCompiledTransform.cs

Executes the transform using the input document specified by the XmlReader object and outputs the results to a TextWriter. The XsltArgumentList provides additional run-time arguments.

public:
 void Transform(System::Xml::XmlReader ^ input, System::Xml::Xsl::XsltArgumentList ^ arguments, System::IO::TextWriter ^ results);

public void Transform (System.Xml.XmlReader input, System.Xml.Xsl.XsltArgumentList? arguments, System.IO.TextWriter results);

public void Transform (System.Xml.XmlReader input, System.Xml.Xsl.XsltArgumentList arguments, System.IO.TextWriter results);

member this.Transform : System.Xml.XmlReader * System.Xml.Xsl.XsltArgumentList * System.IO.TextWriter -> unit

Public Sub Transform (input As XmlReader, arguments As XsltArgumentList, results As TextWriter)

Parameters

input: XmlReader

An XmlReader containing the input document.

arguments: XsltArgumentList

An XsltArgumentList containing the namespace-qualified arguments used as input to the transform. This value can be null.

results: TextWriter

The TextWriter to which you want to output.

Exceptions

ArgumentNullException

The input or results value is null.

XsltException

There was an error executing the XSLT transform.

Remarks

If the style sheet includes an XSLT document() function, it is resolved using an XmlUrlResolver with no user credentials. If the external resource is located on a network resource that requires authentication, use the overload that takes an XmlResolver as one of its arguments and specify an XmlResolver with the necessary credentials.

Transform(IXPathNavigable, XsltArgumentList, XmlWriter)

Source:: XslCompiledTransform.cs

Source:: XslCompiledTransform.cs

Source:: XslCompiledTransform.cs

Executes the transform using the input document specified by the IXPathNavigable object and outputs the results to an XmlWriter. The XsltArgumentList provides additional run-time arguments.

public:
 void Transform(System::Xml::XPath::IXPathNavigable ^ input, System::Xml::Xsl::XsltArgumentList ^ arguments, System::Xml::XmlWriter ^ results);

public void Transform (System.Xml.XPath.IXPathNavigable input, System.Xml.Xsl.XsltArgumentList? arguments, System.Xml.XmlWriter results);

public void Transform (System.Xml.XPath.IXPathNavigable input, System.Xml.Xsl.XsltArgumentList arguments, System.Xml.XmlWriter results);

member this.Transform : System.Xml.XPath.IXPathNavigable * System.Xml.Xsl.XsltArgumentList * System.Xml.XmlWriter -> unit

Public Sub Transform (input As IXPathNavigable, arguments As XsltArgumentList, results As XmlWriter)

Parameters

input: IXPathNavigable

An object implementing the IXPathNavigable interface. In the Microsoft .NET Framework, this can be either an XmlNode (typically an XmlDocument), or an XPathDocument containing the data to be transformed.

arguments: XsltArgumentList

An XsltArgumentList containing the namespace-qualified arguments used as input to the transform. This value can be null.

results: XmlWriter

The XmlWriter to which you want to output.

If the style sheet contains an xsl:output element, you should create the XmlWriter using the XmlWriterSettings object returned from the OutputSettings property. This ensures that the XmlWriter has the correct output settings.

Exceptions

ArgumentNullException

The input or results value is null.

XsltException

There was an error executing the XSLT transform.

Remarks

If the XSLT document() function is enabled, it is resolved using an XmlUrlResolver with no user credentials. If the external resource is located on a network resource that requires authentication, use the overload that takes an XmlResolver as one of its arguments and specify an XmlResolver with the necessary credentials.

This method does not support the xsl:strip-space element. If your compiled style sheet included the xsl:strip-space element, you must use the Transform overload which takes an XmlReader as the input argument.

The IXPathNavigable interface is implemented in the XmlNode and XPathDocument classes. These classes represent an in-memory cache of XML data.

The XmlNode class is based on the W3C Document Object Model (DOM) and includes editing capabilities.
The XPathDocument class is a read-only data store based on the XPath data model. XPathDocument is the recommended class for XSLT processing. It provides faster performance when compared to the XmlNode class.

Transformations apply to the document as a whole. In other words, if you pass in a node other than the document root node, this does not prevent the transformation process from accessing all nodes in the loaded document. To transform a node fragment, you must create an object containing just the node fragment, and pass that object to the Transform method. For more information, see How to: Transform a Node Fragment.

Public Sub Transform (input As XmlReader, arguments As XsltArgumentList, results As XmlWriter, documentResolver As XmlResolver)

Parameters

input: XmlReader

An XmlReader containing the input document.

arguments: XsltArgumentList

An XsltArgumentList containing the namespace-qualified arguments used as input to the transform. This value can be null.

results: XmlWriter

The XmlWriter to which you want to output.

documentResolver: XmlResolver

The XmlResolver used to resolve the XSLT document() function. If this is null, the document() function is not resolved.

Exceptions

ArgumentNullException

The input or results value is null.

XsltException

There was an error executing the XSLT transform.

Examples

The following example uses an XmlSecureResolver to resolve the XSLT document() function.

// Create a resolver and specify the necessary credentials.
XmlSecureResolver resolver = new XmlSecureResolver(new XmlUrlResolver(), "http://serverName/data/");
System.Net.NetworkCredential myCred;
myCred  = new System.Net.NetworkCredential(UserName,SecurelyStoredPassword,Domain);
resolver.Credentials = myCred;

XsltSettings settings = new XsltSettings();
settings.EnableDocumentFunction = true;

// Load the style sheet.
XslCompiledTransform xslt = new XslCompiledTransform();
xslt.Load("http://serverName/data/xsl/sort.xsl", settings, resolver);

// Transform the file.
using (XmlReader reader = XmlReader.Create("books.xml"))
{
   using (XmlWriter writer = XmlWriter.Create("output.xml"))
   {
      xslt.Transform(reader, null, writer, resolver);
   }
}

' Create a resolver and specify the necessary credentials.
Dim resolver As New XmlSecureResolver(New XmlUrlResolver(), "http://serverName/data/")
Dim myCred As System.Net.NetworkCredential
myCred = New System.Net.NetworkCredential(UserName, SecurelyStoredPassword, Domain)
resolver.Credentials = myCred
        
Dim settings As New XsltSettings()
settings.EnableDocumentFunction = True
        
' Load the style sheet.
Dim xslt As New XslCompiledTransform()
xslt.Load("http://serverName/data/xsl/sort.xsl", settings, resolver)
        
' Transform the file.
        Using reader As XmlReader = XmlReader.Create("books.xml")

            Using writer As XmlWriter = XmlWriter.Create("output.xml")
                xslt.Transform(reader, Nothing, writer, resolver)
            End Using

        End Using

Examples

The following example uses an XsltArgumentList object to create a parameter representing the current date and time.

using System;
using System.IO;
using System.Xml;
using System.Xml.Xsl;

public class Sample
{

    public static void Main()
    {

        // Create the XslCompiledTransform and load the stylesheet.
        XslCompiledTransform xslt = new XslCompiledTransform();
        xslt.Load("order.xsl");

        // Create the XsltArgumentList.
        XsltArgumentList xslArg = new XsltArgumentList();

        // Create a parameter which represents the current date and time.
        DateTime d = DateTime.Now;
        xslArg.AddParam("date", "", d.ToString());

        // Transform the file.
        using (XmlWriter w = XmlWriter.Create("output.xml"))
        {
            xslt.Transform("order.xml", xslArg, w);
        }
    }
}

Imports System.IO
Imports System.Xml
Imports System.Xml.Xsl

Public Class Sample

    Public Shared Sub Main()

        ' Create the XslCompiledTransform and load the stylesheet.
        Dim xslt As New XslCompiledTransform()
        xslt.Load("order.xsl")

        ' Create the XsltArgumentList.
        Dim xslArg As New XsltArgumentList()

        ' Create a parameter which represents the current date and time.
        Dim d As DateTime = DateTime.Now
        xslArg.AddParam("date", "", d.ToString())

        Using w As XmlWriter = XmlWriter.Create("output.xml")
            ' Transform the file.
            xslt.Transform("order.xml", xslArg, w)
        End Using

    End Sub
End Class

The example uses the following two data files as input.

order.xml

<!--Represents a customer order-->
<order>
  <book ISBN='10-861003-324'>
    <title>The Handmaid's Tale</title>
    <price>19.95</price>
  </book>
  <cd ISBN='2-3631-4'>
    <title>Americana</title>
    <price>16.95</price>
  </cd>
</order>

order.xsl

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:param name="date"/>
  <xsl:template match="/">
    <order>

Public Sub Transform (input As IXPathNavigable, arguments As XsltArgumentList, results As XmlWriter, documentResolver As XmlResolver)

Parameters

input: IXPathNavigable

The document to transform that is specified by the IXPathNavigable object.

arguments: XsltArgumentList

Argument list as XsltArgumentList.

results: XmlWriter

The XmlWriter to which you want to output.

If the style sheet contains an xsl:output element, you should create the XmlWriter by using the XmlWriterSettings object that is returned from the OutputSettings property. This ensures that the XmlWriter has the correct output settings.

documentResolver: XmlResolver

The XmlResolver used to resolve the XSLT document() function. If this is null, the document() function is not resolved.
