transformNodeToObject Method
Processes this node and its children using the supplied XSL Transformations (XSLT) style sheet and returns the resulting transformation in the supplied object.
Script Syntax
oXMLDOMNode.transformNodeToObject(stylesheet, outputObject);
Parameters
- stylesheet
- An object. A valid XML document or DOM node that consists of XSLT elements that direct the transformation of this node.
- outputObject
- An object. On return, contains the product of the transformation of this XML document based on the XSLT style sheet. If the variant represents the
DOMDocument
object, the document is built according to its properties and its child nodes are replaced during this transformation process. The XML transformation can also be sent to a stream.
Example
The following Microsoft® JScript® example sets up the new XML document object named result
before making the call to transformNodeToObject
.
<SCRIPT> // Load data. var source = new ActiveXObject("Msxml2.DOMDocument.5.0"); source.async = false; source.load("data.xml"); if (xmlDoc.parseError.errorCode <> 0) { var myErr = xmlDoc.parseError; alert("You have error " + myErr.reason); } else { // Load style sheet. var stylesheet = new ActiveXObject("Msxml2.DOMDocument.5.0"); stylesheet.async = false; stylesheet.load("style.xsl"); if (xmlDoc.parseError.errorCode <> 0) { var myErr = xmlDoc.parseError; alert("You have error " + myErr.reason); } else { // Set up the resulting document. var result = new ActiveXObject("Msxml2.DOMDocument.5.0"); result.async = false; result.validateOnParse = true; // Parse results into a result DOM Document. source.transformNodeToObject(stylesheet, result); } } } </SCRIPT>
Visual Basic Syntax
oXMLDOMNode.transformNodeToObject(stylesheet, outputObject)
Parameters
- stylesheet
- An object. A valid XML document or DOM node that consists of XSLT elements that direct the transformation of this node.
- outputObject
- An object. On return, contains the product of the transformation of this XML document based on the XSLT style sheet. If the variant represents the
DOMDocument
object, the document is built according to its properties and its child nodes are replaced during this transformation process. The XML transformation can also be sent to a stream.
Example
The following Microsoft Visual Basic® example demonstrates the application of multiple style sheets to an XML file in succession.
Dim Source As New Msxml2.DOMDocument50 Dim stylesheet As New Msxml2.DOMDocument50 Dim stylesheet2 As New Msxml2.DOMDocument50 Dim result As New Msxml2.DOMDocument50 Dim result2 As New Msxml2.DOMDocument50 ' Load data. Source.async = False Source.Load "sample.xml" If (xmlDoc.parseError.errorCode <> 0) Then Dim myErr Set myErr = xmlDoc.parseError MsgBox("You have error " & myErr.reason) Else ' Load style sheet. stylesheet.async = False stylesheet.Load "stylesheet1.xsl" If (xmlDoc.parseError.errorCode <> 0) Then Dim myErr Set myErr = xmlDoc.parseError MsgBox("You have error " & myErr.reason) Else ' Set up the resulting document. result.async = False result.validateOnParse = True result2.async = False result2.validateOnParse = True ' Parse results into a result DOM Document. Source.transformNodeToObject stylesheet, result stylesheet2.async = False stylesheet2.Load "stylesheet2.xsl" result.transformNodeToObject stylesheet2, result2 MsgBox result2.xml End If End If

C/C++ Syntax
HRESULT transformNodeToObject( IXMLDOMNode *stylesheet, VARIANT outputObject);
Parameters
- stylesheet [in]
- A valid XML document or DOM node that consists of XSL elements that direct the transformation of this node.
- outputObject [in]
- An object that contains the product of the transformation of this XML document based on the XSLT style sheet. If the variant represents
DOMDocument
, the document is built according to its properties and its child nodes are replaced during this transformation process. If the variant contains anIStream
interface, the XML transformation is sent to this stream.
C/C++ Return Values
- S_OK
- The value returned if successful.
- E_INVALIDARG
- The value returned if the
stylesheet
oroutputObject
parameter is Null.
Example
This example sets up the new DOMDocument
object and puts it into a VARIANT before making the call to transformNodeToObject
.
// p is the XML source that is to be transformed, pXSL is the style sheet. // Create an empty DOM document for the result. (Error checking omitted // for brevity.) hr = CoCreateInstance(CLSID_DOMDocument50, NULL, CLSCTX_INPROC_SERVER, IID_IXMLDOMDocument, (void**)&pDoc); hr = pDoc->QueryInterface(IID_IDispatch, (void **)&pDisp); vObject.vt = VT_DISPATCH; // the new object vObject.pdispVal = pDisp; hr = p->transformNodeToObject(pXSL, vObject); // Transformation is // present in pDoc.
Remarks
The stylesheet
parameter must be either a DOMDocument
node, in which case the document is assumed to be an XSLT style sheet, or a DOM node in the XSLT style sheet, in which case this node is treated as a standalone style sheet fragment.
The source node defines a context in which the style sheet operates, but navigation outside this scope is allowed. For example, a style sheet can use the id
function to access other parts of the document.
This method supports both standalone and embedded style sheets and also provides the ability to run a localized style sheet fragment against a particular source node.
The transformNodeToObject
method always generates a Unicode byte-order mark, which means it cannot be used in conjunction with other Active Server Pages (ASP) Response.Write
or Response.BinaryWrite
calls.
