How do I parse this XML in Java with JAXB?

You could do the following. By leveraging @XmlElementWrapper you can reduce the amount of classes that you require:

FosterHome

package nov18;import java.util.List;import javax.xml.bind.annotation.*;@XmlRootElement(name="FosterHome")@XmlAccessorType(XmlAccessType.FIELD)public class FosterHome {    @XmlElement(name="Orphanage")    private String orphanage;    @XmlElement(name="Location")    private String location;    @XmlElementWrapper(name="Families")    @XmlElement(name="Family")    private List<Family> families;    @XmlElementWrapper(name="RemainingChildList")    @XmlElement(name="ChildID")    private List<String> remainingChildren;}

Family

package nov18;import java.util.List;   import javax.xml.bind.annotation.*;@XmlAccessorType(XmlAccessType.FIELD)public class Family {    @XmlElement(name="ParentID")    private String parentID;    @XmlElementWrapper(name="ChildList")    @XmlElement(name="ChildID")    private List<String> childList;}

Demo

package nov18;import java.io.File;import javax.xml.bind.*;public class Demo {    public static void main(String[] args) throws Exception {        JAXBContext jc = JAXBContext.newInstance(FosterHome.class);        Unmarshaller unmarshaller = jc.createUnmarshaller();        FosterHome fosterHome = (FosterHome) unmarshaller.unmarshal(new File("src/nov18/input.xml"));        Marshaller marshaller = jc.createMarshaller();        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);        marshaller.marshal(fosterHome, System.out);    }}

Input/Output

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><FosterHome>    <Orphanage>Happy Days Daycare</Orphanage>    <Location>Apple Street</Location>    <Families>        <Family>            <ParentID>Adams</ParentID>            <ChildList>                <ChildID>Child1</ChildID>                <ChildID>Child2</ChildID>            </ChildList>        </Family>        <Family>            <ParentID>Adams</ParentID>            <ChildList>                <ChildID>Child3</ChildID>                <ChildID>Child4</ChildID>            </ChildList>        </Family>    </Families>    <RemainingChildList>        <ChildID>Child5</ChildID>        <ChildID>Child6</ChildID>    </RemainingChildList></FosterHome>

UPDATE

Is there I easy way I can iterate/print out all the ChildID in the Family class?

You could do the following:

    for(Family family : fosterHome.getFamilies()) {        System.out.println(family.getParentID());        for(String childID : family.getChildList()) {            System.out.println("    " + childID);        }    }

try {    // create a JAXBContext capable of handling classes generated into    // the com.abhi.xml.jaxb.generated package    JAXBContext jc = JAXBContext.newInstance( "com.abhi.xml.jaxb.generated" );    // create an Unmarshaller    Unmarshaller u = jc.createUnmarshaller();    // unmarshal a FosterHome instance document into a tree of Java content    // objects composed of classes from the com.abhi.xml.jaxb.generated     // package.    JAXBElement<?> fhElement =(JAXBElement<?>)u.unmarshal    (new FileInputStream("yourfile.xml"));    FosterHome FH = (FosterHome)fhElement.getValue();    System.out.println(FH.getDesc());         // so on ..you can get all elements based on generated objects} catch( JAXBException je ) {    je.printStackTrace();} catch( IOException ioe ) {    ioe.printStackTrace();}

This seems to be a good tutorial for doing this

It details how to generate an xsd schema from and xml file and then how to use that schema to genenate jaxb classes. In the end you should end up with more than one class.
