The JAXP/TrAX API
 

XSLTC is 100% compliant with the TrAX poriton of the JAXP API. This API is a standard extension to Java and there is not much point in describing it in detail in this document.


XSLTC's extensions to JAXP/TrAX
 

The Source and Result classes within TrAX are used to handle input and output documents. These classes can be extended to encapsulate additional input types. XSLTC's TrAX implementation contains an extension to the Source class:

    org.apache.xalan.xsltc.trax.XSLTCSource

This extension class can be used to build XSLTC's internal DOM and cache it for later usage. The following sample shows how to use it with a Transformer:

    public void run(String xmlfile, String xslfile) {

          // Create an XSLTCSource for the input XML document
          XSLTCSource source = new XSLTCSource(xmlfile);

          // Build a StreamSource for the stylesheet
          StreamSource stylesheet = new StreamSource(xslfile);

          // Create a Transformer instance and process the input
          Transformer transformer = factory.newTransformer(stylesheet);
          transformer.transform(source, new StreamResult(System.out));
	:
	:
    }

If you do chose to implement a DOM cache, you should have your cache implement the javax.xml.transform.URIResolver interface so that documents loaded by the document() function are also read from your cache.
