使用DOM技术实现如下词典功能（1.查询：根据英文单词查中文意思；2.添加：添加英文和中文单词；3.删除：根据英文或中文单词删除中英文词意；4.修改：根据英文单词修改中文注释。）
【代码如下：】
1.【words.xml】
<?xml version="1.0" encoding="UTF-8"?> <words> <word> <en>woman</en> <ch>女</ch> </word> <word> <en>man</en> <ch>男人</ch> </word> <word> <en>girl</en> <ch>女孩</ch> </word> </words>
2.【WordView.html】
