used further. Here is sample XSL Transformation By using
following sample c# code we can effectivly load xml document,
and transform it's content into xhtml by using given xslt
transformation: Now since we know how to transform xml data with
xsl stylesheet and produce valid html code, we can continue with
introducing XSL Extension Objects. Extension objects are used to
extend the functionality of style sheets. Extension objects are
maintained by the XsltArgumentList class. The following are
advantages to using an extension object rather than embedded
script: XSLT extension objects are added to the XsltArgumentList
object using the AddExtension
