8.7. Transforming a DataSet Using XSLT
Problem
You need to use an XSLT stylesheet to
transform the contents of a DataSet.
Solution
Create an
XslTransform object and
call the Transform( ) method.
You’ll need to add the Microsoft Web Browser control to the Toolbox from the COM tab in the Customize Toolbox Dialog. You’ll also need a reference to the Microsoft HTML Object Library from the COM tab in Visual Studio .NET’s Add Reference Dialog.
Example 8-10 uses one XML file:
Category.xsltThe XSLT stylesheet used to transform the XML for the Categories table in the
DataSetinto HTML displaying the Categories data in an HTML table. The contents of this XML file are shown in Example 8-10.
The sample code contains three event handlers:
Form.LoadSets up the sample by filling a
DataSetwith the Categories table from Northwind.- Transform
Button.Click Initializes a
WebBrowsercontrol. Once the control is initialized, theDocumentCompleteevent is raised. The handler for theDocumentCompleteevent completes the XSLT transformation.DocumentCompleteGets the
XmlDataDocumentfor theDataSet, creates anXSLTransformclass, and transforms the XML document using the XSLT stylesheet. The results are displayed both in theWebBrowsercontrol and as XML.
Example 8-10. File: Category.xslt
<?xml version="1.0" encoding="UTF-8" ?> <xsl:stylesheet xmlns:xsl=http://www.w3.org/1999/XSL/Transform version="1.0"> <xsl:template match="/"> <html> <body> <table> <tr bgcolor="#AAAAAA"> <td>Category ID</td> <td>Name</td> <td>Description</td> ...
