Question

我正在通过SAX XML解析器解析一个简单的XML文件，并在列表视图中显示结果。这是成功完成的。现在我想在abc标签关闭时像下面的XML文件那样做。然后下面的标签项不解析（苹果不添加列表视图）。谁能帮我。 Thanx提前

<abc>
   <employee>
    <name>Android</name>
   </employee>
   <employee>
    <name>Nokia</name>
   </employee>
</abc>
   <employee>
    <name>Apple</name>
   </employee>

这是我正在使用的SAXXMLHandler

public class SAXXMLHandler extends DefaultHandler {

    private List<Employee> employees;
    private String tempVal;
    private Employee tempEmp;

    public SAXXMLHandler() {
        employees = new ArrayList<Employee>();
    }

    public List<Employee> getEmployees() {
        return employees;
    }

    // Event Handlers
    public void startElement(String uri, String localName, String qName, Attributes attributes)
            throws SAXException {
        // reset
        tempVal = "";

        if (qName.equalsIgnoreCase("employee")) {
            // create a new instance of employee
            tempEmp = new Employee();

        }
    }

    public void characters(char[] ch, int start, int length) throws SAXException {
        tempVal = new String(ch, start, length);
    }

    public void endElement(String uri, String localName, String qName) throws SAXException {

        if (qName.equalsIgnoreCase("employee")) {
            // add it to the list
            employees.add(tempEmp);
        } else if (qName.equalsIgnoreCase("name")) {
            tempEmp.setName(tempVal);
        }
    }
}

维护一个boolean来控制哪个员工姓名应该添加到列表中，哪个不应该......如下所示......

public class SAXXMLHandler extends DefaultHandler {

    private List<Employee> employees;
    private String tempVal;
    private Employee tempEmp;

    private boolean shouldAdd = false;

    public SAXXMLHandler() {
        employees = new ArrayList<Employee>();
    }

    public List<Employee> getEmployees() {
        return employees;
    }


    public void startElement(String uri, String localName, String qName, Attributes attributes)
            throws SAXException {

        tempVal = "";

        if (qName.equalsIgnoreCase("abc")) {

            shouldAdd = true;

        } else if (qName.equalsIgnoreCase("employee")) {
            // create a new instance of employee
            tempEmp = new Employee();

        }
    }

    public void characters(char[] ch, int start, int length) throws SAXException {
        tempVal = new String(ch, start, length);
    }

    public void endElement(String uri, String localName, String qName) throws SAXException {

        if (qName.equalsIgnoreCase("abc") && shouldAdd == true) {

            shouldAdd = false;

        } else if (qName.equalsIgnoreCase("employee") && shouldAdd == true) {
            // add it to the list
            employees.add(tempEmp);
        } else if (qName.equalsIgnoreCase("name")) {
            tempEmp.setName(tempVal);
        }
    }
}
