Access Parent and child node

I am trying to retrieve attributes for the parent and child nodes. When running the below code I am only getting one line while the XML file has several lines. Can someone point me what I am doing wrong here:
Here is the out put I am getting when running the below code against my xml file:

57511:2011-03-12:2011-03-18:1170108:2011-03-12 1218:2011-03-12 1248

Here is part of the xml file:


<Ed CreationSource="Bluecube" CreationTimestamp="2011-03-23 13:57:01" >
<Unit name="57511" startDate="2011-03-12" endDate="2011-03-18">

</Shift>
</Unit>

Here is my code that attempts to read the above XML file:

Code:

---


static class Entry {
                    final String  BusinessUnit,EmpId,ShiftStart, ShiftEnd, MealStart,MealEnd;
                Entry(String BusinessUnit, String  EmpId,String ShiftStart,String ShiftEnd, String MealStart,String MealEnd) {
                //this.EnterpriseDocument = EnterpriseDocument;
                this.BusinessUnit = BusinessUnit;
                this.EmpId = EmpId;
                this.ShiftStart = ShiftStart;
                this.ShiftEnd = ShiftEnd;
                this.MealStart = MealStart;
                this.MealEnd = MealEnd;
             
           
            }

                    @Override public String toString() {
                           
                    return String.format("%s:%s:%s:%s:%s:%s",BusinessUnit,EmpId, ShiftStart, ShiftEnd, MealStart,MealEnd);
                    }
            }

            final static XPath xpath = XPathFactory.newInstance().newXPath();
            static String evalString(Node context, String path) throws XPathExpressionException {
                    return (String) xpath.evaluate(path, context, XPathConstants.STRING);
            }

            public static void main(String[] args) throws Exception {
                    File file = new File("C:/PunchExport.xml");
                    Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(file);
                    NodeList entriesNodeList = (NodeList) xpath.evaluate("//BU", document, XPathConstants.NODESET);

                    List<Entry> entries = new ArrayList<Entry>();
             
                    for (int i = 0;
                        i < entriesNodeList.getLength();
                        i++) {
                           
                            Node entryNode = entriesNodeList.item(i);
//                        System.out.println(entryNode);
                            entries.add(new Entry(
                                    evalString(entryNode, "@name"), 
                                evalString(entryNode, "@startDate"),
                                evalString(entryNode, "@endDate"),
                                evalString(entryNode, "Shift//@employeeID"),
                                evalString(entryNode, "Shift//Detail//@start"),
                                evalString(entryNode, "Shift//Detail//@end")
                                                           
                                                ));
                        //System.out.println(entries);
                        for (Entry entry : entries) {
                     
                            System.out.println(entry);
               

                        }
                        }
        }}
