[xsl] Invoking XALAN API with an in-memory XML/XSL string

["Roger L. Costello" <costello at mitre dot org>]

Hi Folks,

I have a (Java) program which has two String variables:
 - xml, whose value is the XML, and 
 - xsl, whose value is the stylesheet

I am trying to invoke the XALAN API using these in-memory strings, e.g.,

-- convert the xsl (String) to a byte array and create an instance 
-- of an InputStream:

   ByteArrayInputStream is = new ByteArrayInputStream(xsl.getBytes());

-- create a StreamSource using the input stream:

   StreamSource ss = new StreamSource(is);

-- create a Transformer using the stream source:

   Transformer transformer = tFactory.newTransformer(ss);

When I execute the program I get an error message:

    [Fatal Error] :1:1: Content is not allowed in prolog.

where the following is referenced as the offending instruction:

    Transformer transformer = tFactory.newTransformer(ss);

Note: there is nothing wrong with my stylesheet.  When I run it from the
command line everything works fine.  

Any ideas on what causes this error message?  Have you invoked the XALAN
API with in-memory strings?  How did you do it?  /Roger
