Rich Features of the XSLT Infrastructure
Pass .NET values to the XSLT engine using the
XsltArgumentList.AddParam() method
Call .NET methods from inside the XSLT using Extension
Objects
Available through the XsltArgumentList.AddExtensionObject()
method
Render XSLT results out on the web using the ASP.NET
XmlControl
Open XML Developer Workshop
Passing Values to the XSLT Transformation
XSLT style sheets can receive parameters
<xsl:param name=“discount" />
...
<xsl:value-of select=“@price – (@price * $discount)"/>
String
Boolean
Double

XslCompiledTransform transform = new XslCompiledTransform();
transform.Load("sample.xslt");
XsltArgumentList arguments = new XsltArgumentList();
arguments.AddParam(“discount", "", 0.30);
using (FileStream fs = new FileStream("output.txt"))
{
transform.Transform(document, arguments, fs);
}

Working with Extension Objects
An extension object is a .NET object referenced from
inside the style sheet.
Each method is exposed as a custom function
class MyClass
{
public string MyMethod(
int value) {
…
}
}
<xsl:stylesheet …
xmlns:myNs=“urn:myUrn”>
<xsl:value-of
select=“myNs:MyMethod(123)” />
</xsl:stylesheet>
Open XML Developer Workshop
Pointers on Open XML Transformations
When transforming from Open XML
Access other document parts with the XSLT document() function
<xsl:for-each select="document(other.xml)/my/element">
Resolve paths to external resources using a custom
XmlResolver class
class SampleResolver
: XmlResolver
{
Package _package;
public override object GetEntity(Uri absoluteUri,
string role, Type ofObjectToReturn)
{
PackagePart part = _package.GetPart(absoluteUri);
return part.GetStream();
}
}
