You can set the XMLWriter to be the receiving ContentHandler.
Code:
public class XMLCapitalizer {
public XMLCapitalizer(String infile, String outfile) {
try {
XMLReader eppReader =
XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");
XMLFilter capfilter = new CapitalizerFilter(eppReader);
XMLWriter xmlwriter = new XMLWriter(new FileWriter(outfile));
capfilter.setContentHandler(xmlwriter);
capfilter.parse(infile);
}
catch (Exception e) {
e.printStackTrace();
}
}
