| Accepting the DTD gives the stylesheet processor a bit a of a blank cheque. Entity declarations can be used to include other files. So the processor is prohibited from processing DTD by default.

Applying an XSLT transformation
Simple case
SRC←'C:\Temp\source.xml'
TGT←'C:\Temp\target.txt'
XSL←'C:\Temp\stylesheet.xsl'
⎕USING←'System' 'System.Xml,System.Xml.dll' 'System.Xml.Xsl,System.Xml.dll'
xslt←⎕NEW XslCompiledTransform
xslt.Load⊂XSL
xslt.Transform SRC TGT
XslCompiledTransform replaces XslTransform
.Net 2.0 replaced the XslTransform class with XslCompiledTransform ([http://msdn.microsoft.com/en-us/library/system.xml.xsl.xslcompiledtransform.aspx MSDN article]), making XslTransform obsolete.
XslCompiledTransform is faster than its predecessor and also closes some [http://msdn.microsoft.com/en-us/library/ms172414.aspx security] loopholes in its predecessor, which should be avoided.
Processing Document Type Definitions
The simple example above will not process the files attached to this article. The stylesheet processor rejects the [attachment:forecast.xsl stylesheet], because it contains a short [http://en.wikipedia.org/wiki/Document_Type_Definition DTD] section declaring an entity.
Accepting the DTD gives the stylesheet processor a bit a of a blank cheque. Entity declarations can be used to include other files. So the processor is prohibited from processing DTD by default. But this stylesheet comes from a trusted source and we want the stylesheet processor to accept it.
This is a common situation when processing your own XML files; for example, in converting [http://www.docbook.org DocBook] source into either web pages or camera-ready PDF files. So this otherwise minimal example extends to permitting DTD processing.
SRC←'C:\Temp\forecasts2008.xml'
TGT←'C:\Temp\forecasts.inc'
XSL←'C:\Temp\forecasts.xsl'
xrs←⎕NEW XmlReaderSettings
xrs.ProhibitDtd←0
rdr←XmlReader.Create XSL xrs
xslt←⎕NEW XslCompiledTransform
xslt.Load rdr
xslt.Transform SRC TGTAuthor: StephenTaylor AttachInfo
