我正在尝试使用 javascript将 xml 转换为 javascript 对象。考虑以下示例
**Example 1**
**XML**
<animal>
<dog>dogname1</dog>
<dog>dogname2</dog>
</animal>
**JSON**
animal {
dog : ['dogname1', 'dogname2']
}
**Notice that dog is of type array**
**Example 2**
<animal>
<dog>dogname1</dog>
</animal>
**JSON**
animal {
dog : {'dogname1'}
}
注意这里的狗是字符串类型。问题是我需要它作为数组，即使它的计数只有 1
