对于Java框架（MATSim）的使用，我希望能够从XML导入和导出到Excel（以及从Excel到XML）。为此，我使用XSD文件，但是某些节点必须多次出现。
我的XML文件如下：

但是在Excel中，它将显示如下：
对于一个计划，它最终会显示在5条不同的行上，但是我希望每个计划只能是一个行
id, age, score, selected, type, link, x, y, end_time, mode, dep_time, trav_time, route, start_link, end_link, type, link, x, y, end_time, mode, dep_time, trav_time, route, start_link, end_link, type, link, x, y, end_time
如果我希望可以对它们进行整理，那么我不介意每个计划只使用一行，但是仅将所有数据放在一条线上会真正改变事情并使其易于使用。
我对.XSD不太了解，我只使用在线转换器来创建它。

我试图修改数字“ minOccurs”和“ maxOccurs”，但没有给出预期的结果，据我所知，我什至不知道是否可以这样做。
非常感谢您的宝贵时间。
答案 0 :(得分：0)
您的XSD中有两个错误：
您缺少在<attributes>元素之前（在定界符<plan>之前）复制<!-- =====...==== -->的定义
complexType元素的<activity>需要一个mixed="true"属性，因为
混合的复杂类型元素可以包含属性，元素和文本。
因此，整个XSD应该如下所示（两个更改都带有注释）：

为避免混合内容的必要性，您必须将<activity>元素更改为不包含任何内容（甚至空格）。所以你可以改变
<activity type="h" link="502570" x="645800.341" y="6860736.1577" end_time="07:58:00">
</activity>
到
<activity type="h" link="502570" x="645800.341" y="6860736.1577" end_time="07:58:00" />
或
<activity type="h" link="502570" x="645800.341" y="6860736.1577" end_time="07:58:00"></activity>
但是对于当前的空白，您必须在mixed="true"上使用complexType属性。
