Java - Parsing xml using DOM

Question

I am trying to parse the following xml. I can access the WeekNumber easily but cannot access the children for EmployeeRatesLevelA and EmployeeRatesLevelB. The goal is to sav

Answer 1

As mentioned in the comments, please show us your Java code. You may also want to consider looking at JAXB - the Java Architecture for XML Binding. This is specifically geared towards representing XML as Java objects. It may not be feasible for your solution for whatever reason, but definitely take a look:

DataSet

The following domain object below is what you described in your question:

The goal is to save these to a class, DataSet with fields WeekNumber and ArrayLists, EmployeeRatesLevelA and EmployeeRatesLevelB.

package forum8345529;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlRootElement(name="DataSet")
@XmlAccessorType(XmlAccessType.FIELD)
public class DataSet {

    @XmlElement(name="WeekNumber")
    private int weekNumber;

    @XmlElementWrapper(name="EmployeeRatesLevelA")
    @XmlElement(name="Rate")
    private List employeeRatesLevelA;

    @XmlElementWrapper(name="EmployeeRatesLevelB")
    @XmlElement(name="Rate")
    private List employeeRatesLevelB;

}

Demo

The following code demonstrates how to use the JAXB runtime to convert your XML to/from your domain objects:

package forum8345529;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception{
        JAXBContext jc = JAXBContext.newInstance(DataSet.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum8345529/input.xml");
        DataSet dataSet = (DataSet) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(dataSet, System.out);
    }

}
