Introduction

This editor helps to test the XSL transformations. It is very useful if you are developing XSLT for your web project and want to test before publishing into the web server. You can also check the XSLT syntax errors and the output of the transformation using this editor.

Background

In my recent assignment, I got a chance to work on XSLT. When I was developing XSLT files, I found MSXML.dll does not support all the functions available in the current XSLT/XPath version. So I made this little tool to test the XSLT output and syntax errors.

Using the Code

Dim sResult As New System.IO.StringWriter

'loan XML
xmlDoc.LoadXml(rtxtXML.Text)

'load XSL
xslDoc.LoadXml(rtxtXSL.Text)
Dim xslTransform As New System.Xml.Xsl.XslTransform

'if xsl has any import statements create Evidence For the Url
Dim evidence As System.Security.Policy.Evidence = _
    XmlSecureResolver.CreateEvidenceForUrl("http://localhost/")

evidence.AddAssembly(Me.GetType().Assembly)
xslTransform.Load(xslDoc, New Xml.XmlUrlResolver, evidence)
xslTransform.Transform(xmlDoc, Nothing, sResult, Nothing)
rtxtResult.Text = sResult.GetStringBuilder().ToString()

'select result tab
tbctlMain.SelectedIndex = 2
Trace("Transformation compleated....")

How to Use

1. Copy the XML data in the XML tab or open an existing XML file from the File menu.
Sample XML:
XML

<?xml version='1.0'?>
<!-- This file represents a fragment of a book store inventory database -->
<bookstore>
  <book genre="autobiography" publicationdate="1981" ISBN="1-861003-11-0">
    <title>The Autobiography of Benjamin Franklin</title>
    <author>
      <first-name>Benjamin</first-name>
      <last-name>Franklin</last-name>
    </author>
    <price>8.99</price>
  </book>
  <book genre="novel" publicationdate="1967" ISBN="0-201-63361-2">
    <title>The Confidence Man</title>
    <author>
      <first-name>Herman</first-name>
      <last-name>Melville</last-name>
    </author>
    <price>11.99</price>
  </book>
  <book genre="philosophy" publicationdate="1991" ISBN="1-861001-57-6">
    <title>The Gorgias</title>
    <author>
      <name>Plato</name>
    </author>
    <price>9.99</price>
  </book>
</bookstore>

2. Copy the XSL script in the XSL tab or open an existing XSL file from the File menu.
Sample XSL:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:template match="/">
 <root>
  <xsl:apply-templates/>
 </root>
 </xsl:template>
 <xsl:template match="bookstore">
 <!-- Prices and books -->
  <bookstore>
   <xsl:apply-templates select="book"/>
  </bookstore>
 </xsl:template>
 <xsl:template match="book">
  <book>
   <xsl:attribute name="ISBN">
    <xsl:value-of select="@ISBN"/>
   </xsl:attribute>
   <price><xsl:value-of select="price"/></price><xsl:text>
   </xsl:text>
  </book>
 </xsl:template>
</xsl:stylesheet>

3. Click on the Transform menu item to test the transformation. If the the XSLT is good, then you should see the output on the Result tab.
