Custom Generators - SAX

[Brian Delahunty <bd...@tssg.org>]

Hi,

I'm not sure if this is where I should be asking this.

I'm writing a custom generator that needs to just return an XML document that's contained within a String. Now in the past I have used code like this [Simple Hello-World]:

public class SMSGenerator extends AbstractGenerator {
    AttributesImpl emptyAttr = new AttributesImpl();
    public void generate() throws SAXException
    {
        contentHandler.startDocument();
        contentHandler.startElement("", "abc", "def", emptyAttr);
        contentHandler.characters("Hello World".toCharArray(), 0, "Hello World".length());
        contentHandler.endElement("","abc", "def");
        contentHandler.endDocument();
    }
}

I now have the XML file in a String and I need this to be "returned" by the generator. I was just wondering if anybody knew how to do that without going through the String, breaking it into "Elements" and "characters"

Thanks in advance

Brian

You use a SAX parser, like this:

public void generate() throws SAXException
{
     // ...
     org.xml.sax.XMLReader xr =
         org.xml.sax.helpers.XMLReaderFactory.createXMLReader();
     xr.setContentHandler(this.contentHandler);
     String result = ...;
     xr.parse(new org.xml.sax.InputSource(result.getBytes());
}

This should do the trick. You might have to specify the character 
encoding when converting the String to a byte array with getBytes().
