Fires before the style sheet is applied to a node.
Important Theontransformnode
event does not fire onDOMDocument
for style sheets using the XSLT namespace"http://www.w3.org/1999/XSL/Transform"
. It does, however, fire onDOMDocument
for style sheets using the XSL namespace"http://www.w3.org/XSL/Transform/1.0"
or where MSXML 3.0 is installed you use"http://www.w3.org/TR/WD-xsl"
to declare the older XSL namespace .
boolVal = ontransformnode(nodeCode, nodeData);
True to indicate that transformation processing is to continue; False to indicate that transformation processing should stop.
boolVal = ontransformnode(nodeCode, nodeData)
True to indicate that transformation processing is to continue; False to indicate that transformation processing should stop.
In this example, the XML data island named "target" contains the XML source data, and the XML data island named "ss" contains the XSL Transformations (XSLT) style sheet.
<XML id="target">
<PEOPLE>
<PERSON name="Atkinson, Teresa" />
<PERSON name="Debroux, Steve" />
<PERSON name="O'Hara, Robert" />
<PERSON name="Porzuczek, Peter" />
</PEOPLE>
</XML>
<XML id="ss">
<xsl:template match="/" xmlns:xsl="http://www.w3.org/XSL/Transform/1.0
">
<xsl:for-each select="/PEOPLE/PERSON/@name" >
<P><xsl:value-of /></P>
</xsl:for-each>
</xsl:template>
</XML>
This script contains the Verify
function, which sets the ontransformnode
property to the event handler, onxform
. The event handler is called before the transformation operation on each node so that, given the sample data provided in the data islands, this sample calls the alert several times.
<SCRIPT LANGUAGE="javascript" FOR="window" EVENT="onload"> document.expando = false; Verify(); </SCRIPT> <Script LANGUAGE="javascript"> function onxform ( code, doc ) { alert("Target document node being transformed:\n\n" + doc.xml + "\n\nStylesheet node used for the transform:\n\n" + code.xml); if (doc.value == "O'Hara, Robert") return false; // Stop processing. else return true; } function Verify() { target.ontransformnode = onxform; var sOut = target.XMLDocument.transformNode(ss.XMLDocument); div.innerHTML += sOut; } </Script> <DIV id="div"></DIV> </BODY> </HTML>
The return value from the event handler indicates whether to continue processing. In this example, the event handler checks for a particular data value and returns the value "false" to stop transformation processing.
HRESULT ontransformnode( IXMLDOMNode *pCode, IXMLDOMNode *pData, VARIANT vBool);
The event handler for this event can be explicitly set using the ontransformnode
property.
