Transform problem in ASP.NET v2.0

[Cedric]

Hi,

I have a function from one component that returns an XmlDocument object. I
have another function in another component that takes an XmlDocument as a
property. I have written an XSLT to transform the Xml from the first function
to the format expected by the second function.

But I don't see how I can call the tranformation process in .NET 2.0. It
says that I have to use the XslCompiledTransform class in .NET 2.0, but the
transform function of this class has 14 overloads and none of them accepts
XmlDocument as either input or output parameter. (huh?) The overload that
comes closest to what I need uses an XmlReader and XmlWriter object as
parameters, but how to get my source XmlDocument into the reader and how to
extract the result from the writer? (Without saving it to file first and then
reading it again from file of course)

Any help appreciated. I'm most familiar with VB.NET programming.

Here is the documentation:
<http://msdn2.microsoft.com/en-us/library/ms163429(en-US,VS.80).aspx>
There are several methods that take an object implementing
IXPathNavigable documented here:
<http://msdn2.microsoft.com/en-us/library/h30hxzdh>
XmlDocument is one class that implements that interface, even in .NET 1.1.
So any of those methods can take an XmlDocument instance as the argument.

Martin,

I have looked at this documentation before and am unable to find how to get
my XmlDocument class object to an object of class that is accepted by one of
the transform signatures, and afterwards to get the parsed document back to
an XmlDocument object.

What frustrates me is that I have done this before in ASP 3.0 with MSXML
4.0, where it was a piece of cake: have a document and apply an XSLT to it.
But in .NET, nothing works with the XmlDocument class.

I think you need to take a course in .NET framework object-oriented
programming then to understand that the framework defines interfaces and
classes implementing such interfaces.
And as I said in my previous response:

IXPathNavigable documented here:

XmlDocument is one class that implements that interface, even in .NET 1.1.

So use one of the methods that take an IXPathNavigable argument. That is
an interface and the XmlDocument class implements that interface which
for you means you simply create your XmlDocument instance and then pass
that to the method where the method signature says it wants an
IXPathNavigable.

Pseudo-code C# example for .NET 2.0 that uses an XmlDocument as the input:

XmlDocument xmlDocument = new XmlDocument();
xmlDocument.LoadXml("<gods><god>Kibo</god></gods>");

XslCompiledTransform xsltProcessor = new XslCompiledTransform();
xsltProcessor.Load(@"someStylesheet.xml");

xsltProcessor.Transform(xmlDocument, null, Console.Out);

Martin,

I have been going to some extra material but cannot find how to get the
result back into an XmlDocument. Your example also uses the console.out.
Plenty of examples with XmlWriter and how to save it to disc, but none where
they do any post processing or where they pass it as an argument to another
function.

Any help appreciated.
