20 <title>Xalan Processor Package.</title>
22 <p>Parses an XSLT stylesheet document (which may include and import other stylesheet documents) and produces a StylesheetRoot
23 (a TRaX Templates object).</p>
25 <p>StylesheetProcessor implements the TRaX {@link javax.xml.transform.TransformerFactory} interface,
26 as well as the {@link javax.xml.transform.sax.SAXTransformerFactory} interface.
27 It registers the {@link org.apache.xalan.processor.StylesheetHandler} object
28 (a TrAX {@link javax.xml.transform.sax.TemplatesHandler} implementation)
29 as the SAX ContentHandler for an XMLReader, and uses the XMLReader to parse
30 the stylesheet document.</p>
31 <p>Before parsing the XSLT input, StylesheetHandler assembles an {@link org.apache.xalan.processor.XSLTSchema},
32 which uses {@link org.apache.xalan.processor.XSLTElementDef}
33 and {@link org.apache.xalan.processor.XSLTAttributeDef} objects to
34 recursively define the elements and attributes that an XSLT stylesheet may
35 contain. The StylesheetHandler then passes on each parse event to the
36 {@link org.apache.xalan.processor.XSLTElementProcessor} which the
37 XSLTElementDef assigned to the element associated with that event.</p>
