| <h2>XSLTC TrAX API</h2> |
| |
| <p align="right" size="2"> |
| <a href="#content">(top)</a> |
| </p> |
| <h3>The JAXP/TrAX API</h3> |
| |
| <p>XSLTC is 100% compliant with the TrAX poriton of the |
| <a href="http://java.sun.com/xml/jaxp/index.html">JAXP API</a>. This |
| API is a standard extension to Java and there is not much point in describing |
| it in detail in this document.</p> |
| |
| |
| |
| <p align="right" size="2"> |
| <a href="#content">(top)</a> |
| </p> |
| <h3>XSLTC's extensions to JAXP/TrAX</h3> |
| |
| <p>The <code>Source</code> and <code>Result</code> 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 <code>Source</code> class:</p> |
| <blockquote class="source"> |
| <pre> |
| org.apache.xalan.xsltc.trax.XSLTCSource</pre> |
| </blockquote> |
| |
| <p>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 <code>Transformer:</code> |
| </p> |
| <blockquote class="source"> |
| <pre> |
| 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)); |
| : |
| : |
| }</pre> |
| </blockquote> |
| |
| <p>If you do chose to implement a DOM cache, you should have your cache |
| implement the <code>javax.xml.transform.URIResolver</code> interface so |
| that documents loaded by the <code>document()</code> function are also read |
| from your cache.</p> |
