如何使用XML或Java代碼

我的.xml文檔以獲得以xml一種元素的標籤的數量包含數據是這樣的：如何使用XML或Java代碼

<Test-Set> 
<Test-Case Name="Verify using Interface user in WebService we are able to do database transactions" /> 
<Test-Case Name="Verify using Interface user in JMS we are able to post a message to queue and get message from queue" /> 
<Test-Case Name="Verify using Interface user we are able to login BPD"/> 
</Test-Set>

我的預期的輸出是：3

未測試：

public class Demo { 

    public static void main(String[] args) throws Exception { 
     String xml = "<Test-Set> " + 
        "<Test-Case Name=\"Verify using Interface user in WebService we are able to do database transactions\" />" + 
        "<Test-Case Name=\"Verify using Interface user in JMS we are able to post a message to queue and get message from queue\" />" + 
        "<Test-Case Name=\"Verify using Interface user we are able to login BPD\"/>" + 
        "</Test-Set>"; 
     DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 

     DocumentBuilder builder = factory.newDocumentBuilder(); 

     Document document = builder.parse(new ByteArrayInputStream(xml.getBytes())); 
     String xpath = "count(Test-Set/TestCase)"; 
     XPath xPath = XPathFactory.newInstance().newXPath(); 
     Double s = (Double) xPath.evaluate(xpath, document, XPathConstants.NUMBER); 
    } 

}
