Script Syntax

objXSLProcessor.addParameter(baseName, parameter, namespaceURI);

Parameters

baseName

The name that will be used inside the style sheet to identify the parameter context.

parameter

In most cases, a number, Boolean, string, IXMLDOMNodeList, or IXMLDOMNode. Passing in a single node will produce a node list that contains one node (shortcut). To remove a parameter previously added to the processor, provide a value of Empty or Null instead. This acts as a signal to the processor to remove any previously added parameter of the same name.

namespaceURI (optional)

An optional namespace.

Example

var xslt = new ActiveXObject("Msxml2.XSLTemplate.5.0");
var xslDoc = new ActiveXObject("Msxml2.FreeThreadedDOMDocument.5.0");
var xslProc;
xslDoc.async = false;
xslDoc.load("sample.xsl");
if (xmlDoc.parseError.errorCode <> 0) {
   var myErr = xmlDoc.parseError;
   alert("You have error " + myErr.reason);
} else {
   xslt.stylesheet = xslDoc;
   var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0");
   xmlDoc.async = false;
   xmlDoc.load("books.xml");
   if (xmlDoc.parseError.errorCode <> 0) {
      var myErr = xmlDoc.parseError;
      alert("You have error " + myErr.reason);
   } else {
      xslProc = xslt.createProcessor();
      xslProc.input = xmlDoc;
      xslProc.addParameter("param1", "Hello");
      xslProc.transform();
      alert(xslProc.output);
   }
}

Visual Basic Syntax

objXSLProcessor.addParameter(baseName, parameter, namespaceURI)

Parameters

baseName

The name that will be used inside the style sheet to identify the parameter context.

parameter

A number, Boolean, string, IXMLDOMNodeList, or IXMLDOMNode. Passing in a single node will produce a node list that contains one node (shortcut). To remove a parameter previously added to the processor, provide a value of Empty or Null instead. This acts as a signal to the processor to remove any previously added parameter of the same name.

namespaceURI (optional)

An optional namespace.

Example

Dim xslt As New Msxml2.XSLTemplate50
Dim xslDoc As New Msxml2.FreeThreadedDOMDocument50
Dim xmlDoc As New Msxml2.DOMDocument50
Dim xslProc As IXSLProcessor
xslDoc.async = False
xslDoc.Load "sample.xsl"
If (xmlDoc.parseError.errorCode <> 0) Then
   Dim myErr
   Set myErr = xmlDoc.parseError
   MsgBox("You have error " & myErr.reason)
Else
   Set xslt.stylesheet = xslDoc
   xmlDoc.async = False
   xmlDoc.Load "books.xml"
   If (xmlDoc.parseError.errorCode <> 0) Then
      Dim myErr

      xslProc.input = xmlDoc
      xslProc.addParameter "param1", "Hello"
      xslProc.Transform
      MsgBox xslProc.output

C/C++ Syntax

HRESULT addParameter (BSTR baseName, VARIANT parameter, BSTR 
namespaceURI);

Parameters

baseName [in]

The name that will be used inside the style sheet to identify the parameter context.

parameter [in]

A number, Boolean, string, node list, or node. Passing in a single node will produce a node list that contains one node (shortcut). To remove a parameter previously added to the processor, you can pass a value of VT_EMPTY, VT_NULL, or a NULL IDispatch or IUnknown instead. This acts as a signal to the processor to remove any previously added parameter of the same name.

namespaceURI [in, optional]

An optional namespace.

C/C++ Return Values

E_FAIL if readyState is READYSTATE_INTERACTIVE.
