我正在尝试使用 java 脚本解析一个简单的 xml 文件。当我将文件加载到网络浏览器“Chrome”中时,页面什么也不显示。
请让我知道我的错误是什么。
xml 文件:
< ?xml version="1.0" encoding="UTF-8" ?>
<company>
<employee id="001" >John</employee>
<turnover>
<year id="2000">100,000</year>
<year id="2001">140,000</year>
<year id="2002">200,000</year>
</turnover>
</company>
JAvaScript 解析器:
