StreamTransform: Write output to a buffer

[Nithya Nirmal Vijayakumar]

Hi,

I am a new user to Xerces-C++. I want to apply xsl transformation to xml 
stored in a buffer and get the output into a buffer.

The StreamTransform.cpp example reads from a buffer and writes output to a 
stream. I tried modifying this to write to a buffer. I followed the same 
pattern defined in the example for converting the buffer to a stream.

-----------------
//code from StreamTransform example to convert
//input buffer to XSLTInputsource

	istrstream	theXMLStream(theInputDocument, 
strlen(theInputDocument));
	istrstream	theXSLStream(theStyleSheet, 
strlen(theStyleSheet));
        XALAN_USING_XALAN(XalanDOMString)
          XALAN_USING_XALAN(XSLTInputSource)
        XSLTInputSource  inputSource(&theXSLStream);
        inputSource.setSystemId(XalanDOMString("foo").c_str());

//code I added to convert output buffer to
//XSLTResultTarget

        ostrstream      theOutputStream(outputBuffer, 
strlen(outputBuffer));
        XALAN_USING_XALAN(XalanDOMString)
          XALAN_USING_XALAN(XSLTResultTarget)
        XSLTResultTarget outputStream(&theOutputStream);

// Do the transform.
	theResult = theXalanTransformer.transform(&theXMLStream, 
inputSource, outputStream);
----------------------

It compiles fine. But when I run it, I get

StreamTransform Error:
XalanStdOutputStreamWriteException: Error writing to standard stream.The 
error code is '2'. (, line -1, column -1)

Could someone please tell me what is wrong here? If anyone can provide me 
with an example of writing the transform output to a buffer, that will be 
very helpful.

thank you,
Nithya
