This isn't a priority, but it's a problem that is bugging me and I
would like to know why it's happening.
I'm using xercesImpl- 2.2.1.jar,xercesImpl.jar, xalan-2.4.1.jar
and I have fop.jar (0.20.5) in the classpath.
When I create a Dom object of the xml and run the following code in
java:
// Create the Transformer that takes the XML DOM and converts it
// into XML in memory
TransformerFactory transfact = TransformerFactory.newInstance();
Transformer transformer = transfact.newTransformer(xslSource);
DOMSource dsSource = new DOMSource(xmlDoc.getDocumentElement());
if (transformer != null) {
transformer.transform(dsSource, drResult);
foOutDoc = (Document)drResult.getNode();
}else{
System.err.println("No Transformer");
}
The resulting DOM object starts with the information in the
apply-template match="root" not "/"
Here is the xml:
<?xml version="1.0"
encoding="UTF-8"?><root><piechartamount>77.3</piechartamount></root>
And here is the xsl:

Sorry for the long email, Like I said it's puzzling me and I would like
to understand why it is happening.
Thanks,
