How to get jaxb to Ignore certain data during unmarshalling

Question

I have a xml structure \"Filter\" that get unmarshalled into in a java class called \"Filter\".

The XML state looks roughly like:

  &         


        

Answer 1

For this use case I would create an XSLT that will convert the XML document. Then using the javax.xml.transform.* APIs, transform the XML to a JAXBResult to unmarshal the object:

import java.io.File;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.util.JAXBResult;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamSource;

public class Demo {

    public static void main(String[] args) throws Exception {
        TransformerFactory tf = TransformerFactory.newInstance();

        File xsltFile = new File("transform.xsl");
        StreamSource xsltSource = new StreamSource(xsltFile);
        Transformer transformer = tf.newTransformer(xsltSource);

        File xml = new File("input.xml");
        StreamSource xmlSource = new StreamSource(xml);

        JAXBContext jc = JAXBContext.newInstance(Filter.class);
        JAXBResult jaxbResult = new JAXBResult(jc);

        transformer.transform(xmlSource, jaxbResult);

        Filter filter = (Filter) jaxbResult.getResult();
    }

}

transform.xsl
