And yes, I am using 2.2. Henrik Pettersen http://www.ontologyx.com
-----Original Message----- From: Erik Bruchez [mailto:[EMAIL PROTECTED] Sent: 17 March 2004 19:08 To: OXF Users Subject: Re: Memory footprints Hi Enrik, The OXF pipelines are 100% SAX-based. There are some exceptions, in particular: o Conditionals (p:choose) which may require building XML trees to apply certain XPath expressions to the documents referenced by the p:choose's href attribute. o Debug attributes on inputs and outputs currently build trees. o Schema validation on inputs and outputs may require building trees, depending on the validator used. Also, Saxon will build an internal tree for input documents, which is not a DOM tree but Saxon's own "tinytree". This is in the general case unavoidable as XSLT and XPath require being able to navigate the input documents along all axes. In your case, I think the issue you are encountering is that the serializer is storing the output document into the OXF cache. Our current code base supports disabling caching of serialized content, similar to what we allow in 2.2 for the URL generator: http://www.orbeon.com/oxf/doc/processors-generators#N103B3 Are you currently using 2.2? We should be able to provide you with a snapshot build with this feature. -Erik Henrik Pettersen wrote: > Hello, > > I'm parsing a large xml file using the saxon xslt parser, generating an > even larger xml file which I write out to disk. > > Problem is that OXF seems to create an in-memory model of the results, > which it does not release after the file has been written out. > > 2 questions: > ------------ > 1.
