Question

我不确定为什么XML和XSD代码都在浏览器中显示错误消息。我试图根据错误纠正两者，但仍然没有正确

浏览器中的XML显示：“第16行第11行的错误：打开和结束标记不匹配：元行0和头部”

浏览器中的XSD显示：“第15行第31行的错误：打开和结束标记不匹配：元素行0和所有”

Answer 1

答案在评论中，你真的应该使用XML解析器，但要明确：

在XML文件中，最后一行应为

</nutrition:items>

注意：商品 s 不是商品

在XSD文件中定义的第三行

<complexType name = "productType">

应该是

<element name = "product" type = "string"/>

注意：/>不仅仅是>。
