| <body> |
| Provides <a href="http://sax.sourceforge.net/">SAX 2.0</a> adapters for ASM |
| visitors to convert classes to and from XML. |
| These adapters can be chained with other SAX compliant content handlers and |
| filters, eg. XSLT or XQuery engines. This package is bundled as |
| a separate <tt>asm-xml.jar</tt> library and requires <tt>asm.jar</tt>. |
| <p> |
| <tt>ASMContentHandler</tt> and <tt>SAXClassAdapter/SAXCodeAdapter</tt> |
| are using <a href="asm-xml.dtd">asm-xml.dtd</a>. |
| Here is the example of bytecode to bytecode XSLT transformation. |
| |
| <pre> |
| SAXTransformerFactory saxtf = ( SAXTransformerFactory) TransformerFactory.newInstance(); |
| Templates templates = saxtf.newTemplates( xsltSource); |
| |
| TransformerHandler handler = saxtf.newTransformerHandler( templates); |
| handler.setResult( new SAXResult( new ASMContentHandler( outputStream, computeMax))); |
| |
| ClassReader cr = new ClassReader( bytecode); |
| cr.accept( new SAXClassAdapter( handler, cr.getVersion(), false), false); |
| </pre> |
| |
| See JAXP and SAX documentation for more detils. |
| |
| <p> |
| There are few illustrations of the bytecode transformation with XSLT in |
| examples directory. The following XSLT procesors has been tested. |
