Parsing XML file retrieved through HTTP

["Kransen, J." <j....@srn.minjus.nl>]

Hello, 

I have a .jsp that outputs a XML file. I have another .jsp in which I want
to parse the XML file using an XSL file. So in the latter .jsp I want to do
something like this:

<textarea><%

String xslFile = getServletContext().getRealPath("/xml/risc2cvs.xsl");

TransformerFactory tFactory = TransformerFactory.newInstance(); Transformer
transformer = tFactory.newTransformer(new StreamSource(xslFile));

// write the content of the parsed XML file 
transformer.transform(new
StreamSource("http://localhost/risc/readonly.jsp"), new StreamResult(out));

%></textarea>

However, when I do this, I get the following error message:

The element type "base" must be terminated by the matching end-tag "".

With this stack trace:
javax.xml.transform.TransformerException: The element type "base" must be
terminated by the matching end-tag "".

	at
org.apache.jsp.cvs_005fuittreksel_jsp._jspService(cvs_005fuittreksel_jsp.jav
a:109)
...


When instead I try to parse a local XML file, there are no problems: 
String xmlFile = getServletContext().getRealPath("/xml/temp.xml");
transformer.transform(new StreamSource(xmlFile), new StreamResult(out));

But then, when I try to parse the very same file as accessed through HTTP, I
get the very same error: 
transformer.transform(new
StreamSource("http://localhost/risc/xml/temp.xml"), new StreamResult(out));

I was thinking that maybe the HTTP headers aren't stripped before the
parsing. Does anybody know what to do here?

Thanks in advance!

Jeroen,

Did you look at the xml file through a brower?  Maybe there is something
there you aren't seeing.  I have done the exact same thing, opening an
http page as a streamsource, using php as the source.  Every error I saw
came in malformed xml.  Which is what it sounds like you have.
