Generating SAX Parsing Events by Traversing a DOM Document
If you have developed a set of handlers for SAX events, it is possible
to use these handlers on a source other than a file. This example
demonstrates how to use the handlers on a DOM document.
// Obtain a DOM document; this method is implemented in
// The Quintessential Program to Create a DOM Document from an XML File
Document doc = parseXmlFile("infilename.xml", false);
// Prepare the DOM source
Source source = new DOMSource(doc);
// Set the systemId of the source. This call is not strictly necessary
URI uri = new File("infilename.xml").toURI();
source.setSystemId(uri.toString());
// Create a handler to handle the SAX events
DefaultHandler handler = new MyHandler();
try {
// Prepare the result
SAXResult result = new SAXResult(handler);
// Create a transformer
Transformer xformer = TransformerFactory.newInstance().newTransformer();
// Traverse the DOM tree
xformer.transform(source, result);
} catch (TransformerConfigurationException e) {
} catch (TransformerException e) {
}
// DefaultHandler contain no-op implementations for all SAX events.
// This class should override methods to capture the events of interest.
class MyHandler extends DefaultHandler {
}
Thank you!!! You don't know how much searching it took me to find this!
