XPATH更好的方式來解析XML

Question

有什麼更好的方式來解析這樣的xml：

<FindLicensesResponse xmlns="http://abc.com"> 
<FindLicensesResult> 
    <Licensies> 
     <ActivityLicense> 
      <id>1</id> 
      <DateIssue>2011-12-29T00:00:00</DateIssue> 
      <ActivityType xmlns:s01="http://www.w3.org/2001/XMLSchema-instance" s01:type="ActivityType"> 
       <code>somecode1</code> 
      </ActivityType> 
      <ActivityTerritory xmlns:s02="http://www.w3.org/2001/XMLSchema-instance" s02:type="Territory"> 
       <code>somecode2</code> 
      </ActivityTerritory> 
      <ActivityLicenseAttachments /> 
     </ActivityLicense> 
     <ActivityLicense> 
      <id>2</id> 
      <DateIssue>2011-12-21T00:00:00</DateIssue> 
      <ActivityType xmlns:s01="http://www.w3.org/2001/XMLSchema-instance" s01:type="ActivityType"> 
       <code>somecode3</code> 
      </ActivityType> 
      <ActivityTerritory xmlns:s02="http://www.w3.org/2001/XMLSchema-instance" s02:type="Territory"> 
       <code>somecode4</code> 
      </ActivityTerritory> 
      <ActivityLicenseAttachments /> 
     </ActivityLicense> 
    </Licensies> 
</FindLicensesResult> 

我需要從每個ActivityLicense值：ID，DateIssue和內部ActivityType：代碼和內部ActivityTerritory ：代碼。

現在我這樣做是這樣的：

CachedXPathAPI xpathAPI = new CachedXPathAPI(); 
Element nsctx = result.getSOAPPart().createElementNS(null, "nsctx"); 
nsctx.setAttributeNS("http://www.w3.org/2000/xmlns/","xmlns:el","http://abc.com"); 
NodeList activityLicenses = xpathAPI.selectNodeList(result.getSOAPPart(),"//el:ActivityLicense", nsctx); 

for (int i = 0; i < activityLicenses.getLength(); i++) { 
    Node id = xpathAPI.selectSingleNode(activityLicenses.item(i), "//el:id", nsctx); 
    Node dateIssue = xpathAPI.selectSingleNode(activityLicenses.item(i), "//el:DateIssue",nsctx); 

    System.out.println("id: " + id.getTextContent()); 
    System.out.println("dateIssue: " + dateIssue.getTextContent()); 
} 

但我不能得到ActivityType /代碼和ActivityTerritory /代碼

退房這一解決方案價值
