Java 用于读取XML文件的DOM解析器（编辑）

我想使用DOM解析器读取以下XML文件

 <?xml version="1.0" encoding="UTF-8"?>
<CCL>
    <COUNTRY>
       <COUNTRYNAME>INDIA</COUNTRYNAME>
        <CITY>
            <CITYNAME>NOIDA</CITYNAME>
            <LOCALITY>SEC 22^SEC 24^SEC 55</LOCALITY>
        </CITY>
        <CITY>
            <CITYNAME>DELHI</CITYNAME>
            <LOCALITY>MAYUR VIHAR^PATPARGANJ^CHANDNI CAHUK</LOCALITY>
        </CITY>
    </COUNTRY>
    <COUNTRY>
       <COUNTRYNAME>SINGAPORE</COUNTRYNAME>
        <CITY>
            <CITYNAME>TIONG BAHRU</CITYNAME>
            <LOCALITY>BLK 150^BLK 154^BLK 129</LOCALITY>
        </CITY>
        <CITY>
            <CITYNAME>TANJONG PAGAR</CITYNAME>
            <LOCALITY>MAXWELL ROAD^CECILL STREET^AXA TOWER</LOCALITY>
        </CITY>
    </COUNTRY>
</CCL>

我想阅读每个国家的城市标签中的所有条目

**

我能读国家标签，但我不知道如何读城市， 每个国家/地区的城市名称。请帮帮我

有人能帮我解决这个问题吗？

看起来您只是从CITYNAME&Location日志消息中引用了错误的元素

尝试从以下位置更改：

 if (nNode_1.getNodeType() == Node.ELEMENT_NODE) {
                    Element eElement_1 = (Element) nNode_1;

     log.info("CITYNAME: " + getTagValue("CITYNAME", eElement));
    log.info("LOCALITY: " + getTagValue("LOCALITY", eElement));

 }

致：

我不能确定，因为我看不到getTagValue的定义，但看起来很有可能

你得到了什么？换句话说，描述问题。我不相信nNode23是一个好的变量名。谢谢，我已经编辑了这个问题。
