Hi,
I am transforming XML in a servlet. The logic is simple. Client sends the XML in content of HTTP Post. The XML contains the name of Stylesheet with <xml-stylesheet> Processing Instruction.
However, when I try to do the transformation I get the TransformException
It seems to me that if I try to use xmlSource then it looses it's contents. So if I use it next time, I get some form of exception -
The exception looks as follows:
The root element is required in a well-formed document.javax.xml.transform.TransformerException: The root element is req
uired in a well-formed document.

The root element is required in a well-formed document.javax.xml.transform.TransformerException: The root element is req
uired in a well-formed document.

It seems that you deal with a document which is not well-formed.
Cheers,
Dan

Well, the xmlSource document is somehow getting lost and I get this exception.
It will be really helpful if you can tell me why that is happening. Seems to me that when I use xmlSource the first time for getAssociatedStylesheet(), the xmlSource content gets lost (like an EOF of some kind)
 
I agree. Here's the link: http://aspose.com/file-tools
