XSLT, coming from ASP model

[Eric Phetteplace]

Hello,

I am moving over from using msxml2.domdocument to system.xml and
system.xml.xsl.

I'd like to present this to my group today, so your help is appreciated.

I want to transform an XML object (built on the fly) with an XSL document
(URL to document) and have it return a string object for my function.

Here's where I am:

Function x as String
'this function will return transformed xml
Dim oXML as New System.xml.xmldocument
oXML.LoadXML("<document/>")

oXSL as New System.xml.xmldocument
oXSL.Load([stylesheet])

x = ???
End Function

I started down the path of creating an XMLReader class, and I was going to
"read" that into x. Am I on the right track?

Your help is appreciated,

Eric

No, that's MSXML model. In .NET you better use the following (C# code):

XmlDocument doc = new XmlDocument();
//Build it
doc.LoadXml("<doc/>");
XslTransform xslt = new XslTransform();
//Load stylesheet (you should use here Server.MapPath in ASP.NET)
xslt.Load("whatever.xsl");
StringWriter sw = new StringWriter();
//Run transformation
xslt.Transform(doc, null, sw, null);
sw.Close();
return sw.ToString()

Additionally consider caching compiled XslTransform object for
repetitive transformations.

Thanks Oleg, that's what I needed.

However, when I try to compile, (forgive the paraphrasing, as I'm not in
front of my .NET machine) I get an error saying there isn't a Transform
method with these parameter types. There are 18 definitions of the
Transform method. I had to use chr(0) in place of the NULL keyword, since
there is no NULL in VB.NET.

Perhaps it doesn't recognize my null? System.DBNull didn't help. Perhaps
it's the XMLDocument?

Hmm. Which .NET version are you using? There is a difference in
XslTransform API between .NET 1.0 and 1.1. I meant the following method:

[Visual Basic] Overloads Public Sub Transform(IXPathNavigable,
XsltArgumentList, TextWriter, XmlResolver)
[C#] public void Transform(IXPathNavigable, XsltArgumentList,
TextWriter, XmlResolver);

XmlDocument is IXPathNavigable and StringWriter is TextWriter.
I had to use chr(0) in place of the NULL keyword, since
there is no NULL in VB.NET.

It's Nothing as far as I know. in VB.NET you should have something like

xslt.Transform(doc, Nothing, sw, Nothing)

Using 'Nothing' in place of 'null' solved the problem.

Thanks again Oleg. You've been most helpful.
