Question

我正在尝试使用xsd验证pdf文件文档，其中我将给定的pdf转换为xml并通过模式xsd解析它并验证，但我们假设有一个标题，它有2个小标题我该怎么办？更改为xsd模式，以便对于特定类型的标题，它应该并且必须至少有2个特定文本（单词/句子）的子标题，如何为xsd文件添加条件以验证特定设计的文档？

这是xsd

    <?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
  <xs:element name="elements">
    <xs:complexType>
      <xs:sequence>
        <xs:element maxOccurs="unbounded" ref="element"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="element">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="pageno"/>
      </xs:sequence>
      <xs:attribute name="level" use="required" type="xs:integer"/>
      <xs:attribute name="title" use="required"/>
      <xs:attribute name="type" use="required"/>
    </xs:complexType>
  </xs:element>
  <xs:element name="pageno" type="xs:integer"/>
</xs:schema>

这是我用来生成xsd的xml：

<elements>
<element type ="Introduction" level="1" title="Introduction">
<pageno>4</pageno>
</element>
<element type ="Introduction" level="2" title="Enhancements to the HP CSA vCenter Simple Compute">

</elements>

如果您认为我缺乏明确性，那么请告诉我，我会回答任何问题。谢谢

Answer 1

您可以定义自己的Schema类型，它是必须包含特定文本的标题，如果您的实现支持，则使用XSD 1.1的条件类型赋值功能。

更广泛支持的方法是在架构中嵌入Schematron规则以执行您想要的操作。

请记住，如果过度约束输入，架构可能会变得脆弱 - 也就是说，如果发生变化，很难维护。

Xsd条件实现
