从 jdom 中的文档读取文本时出错？

我来这里是想问你一个关于jdom的基本问题。我正在尝试读取 Document 对象，但总是出现错误。我正在尝试阅读的文档是，

<message>
<header>
<messageType>snmp</messageType>
<sendFrom>192.168.0.16</sendFrom>
<hostName>oghmasysMehmet</hostName>
<sendTo>192.168.0.12</sendTo>
<receiverName>Mehmet</receiverName>
<date>03/10/2011</date>
</header>
<body>
<snmpType>getbulk</snmpType>
<ip>127.0.0.1</ip>
<port>161</port>
<oids>
  <oid>1.3.6.1.2.1.1</oid>
</oids>
<community>public</community>
<nR>0</nR>
<mR>5</mR>
</body>
</message>

并且我正在尝试评估。为此，我编写了一个函数，

public Vector<String> getOIDs(Document document){ 

    Vector<String> oids = new Vector<String>();

    Element root = document.getRootElement();
    Element body = root.getChild("body");
    //Element element = body.getChild("oids");
    List rows = body.getChildren("oid");
    for (int i = 0; i < rows.size(); i++) {
        Element row = (Element) rows.get(i);
        String s = row.getText();
        oids.add(s);
    }
    return oids;
}

但是当我调试它时，我总是可以看到该函数没有读取任何内容。你能帮我一下吗？

谢谢大家

编辑：好吧，很抱歉问了这样一个菜鸟问题，我只是在 getchildren (); 中犯了一个错误。我应该写 oids 而不是 oid

编辑2：实际上，我在评论我的问题时更改了代码，但现在，我读到的唯一内容是“\n \n”而不是“1.3.6.1.2.1.1”。您认为问题可能是什么？

I am here to ask you a basic question about jdom. I am trying to read a Document object but I got an error all the time.
The Document that I am trying to read is,

<message>
<header>
<messageType>snmp</messageType>
<sendFrom>192.168.0.16</sendFrom>
<hostName>oghmasysMehmet</hostName>
<sendTo>192.168.0.12</sendTo>
<receiverName>Mehmet</receiverName>
<date>03/10/2011</date>
</header>
<body>
<snmpType>getbulk</snmpType>
<ip>127.0.0.1</ip>
<port>161</port>
<oids>
  <oid>1.3.6.1.2.1.1</oid>
</oids>
<community>public</community>
<nR>0</nR>
<mR>5</mR>
</body>
</message>

And I am trying to value. To do it, I have written a function,

public Vector<String> getOIDs(Document document){ 

    Vector<String> oids = new Vector<String>();

    Element root = document.getRootElement();
    Element body = root.getChild("body");
    //Element element = body.getChild("oids");
    List rows = body.getChildren("oid");
    for (int i = 0; i < rows.size(); i++) {
        Element row = (Element) rows.get(i);
        String s = row.getText();
        oids.add(s);
    }
    return oids;
}

but When I debug it, I can always see that there is nothing read by the function.
Can you please help me about that ?

Thank you all

EDIT :Ok sorry for asking such a noob question, I just made a mistake in getchildren (); I should have written oids instead of oid

EDIT 2: Actually ı have changed the code as I commented on my question but now, the only thing I read is "\n \n" not "1.3.6.1.2.1.1". What do you think the problem might be ?

乍一看，在我看来，它没有“oid”孩子，它有一个“oids”孩子。您尝试读取的元素位于“oids”元素内。

您可以尝试逐步调试它，看看哪些元素没有被读取。这将是我在不尝试的情况下最好的猜测。

您注释掉的行是正确的，只需更新其下面的行即可匹配。您的列表应该是：

 Vector<String> oids = new Vector<String>();
 Element root = document.getRootElement();
 Element body = root.getChild("body");
 Element element = body.getChild("oids");
 List rows = element.getChildren("oid");
 for (int i = 0; i < rows.size(); i++) {
      Element row = (Element) rows.get(i);
      String s = row.getText();
      oids.add(s);
 }
 return oids;

Your commented out line was correct, the line below it just needs to be updated to match. Your listing should be:

 Vector<String> oids = new Vector<String>();
 Element root = document.getRootElement();
 Element body = root.getChild("body");
 Element element = body.getChild("oids");
 List rows = element.getChildren("oid");
 for (int i = 0; i < rows.size(); i++) {
      Element row = (Element) rows.get(i);
      String s = row.getText();
      oids.add(s);
 }
 return oids;
