从xml生成xsd时mixed=为“true”

Question

我正在尝试使用intelliJ从现有的XML文件中生成XSD。但是生成的xsd有这个- 'mixed =“true”属性，我不希望最终生成的类(使用xjc)包含它的成员作为Serializable属性，这是我不想要的。有没有人知道我该怎么防止这种情况发生？

XML文件-

<?xml version="1.0" encoding="UTF-8"?>
<STEPS>
    <STEP>
        <taskId>1</taskId>
        <dependency>

        </dependency>
        <task>Sample Step</task>
        <techDetail>SVN Script path</techDetail>
        <description>Sample step</description>
        <comments>No commnets</comments>
    </STEP>
    <STEP>
        <taskId>2</taskId>
        <dependency>
            <dependanttaskId>1</dependanttaskId>
        </dependency>
        <task>Second Sample Step</task>
        <techDetail>SVN Script Path Again</techDetail>
        <description>Sample step 2</description>
        <comments>No comments again</comments>
    </STEP>
    <STEP>
        <taskId>3</taskId>
        <dependency>
            <dependanttaskId>1</dependanttaskId>
            <dependanttaskId>2</dependanttaskId>
        </dependency>
        <task>Third Sample Step</task>
        <techDetail>SVN Script Path Again</techDetail>
        <description>Sample step 3</description>
        <comments>No comments again 3</comments>
    </STEP>
</STEPS>

Answer 1

从<dependency>``</dependency>中删除空格，并将其作为<dependency/>提及

当需要在parent的子元素之间允许某些字符时，就会出现

• mixed=true，在本例中parent为dependency。因此，我假设dependency元素中存在一个类似于空格的字符。
