PHSchematron无法使用`pattern`元素中的`p`元素验证schematron文件

Question

目前，我正在使用PHSchematron库来验证Java中的schematron。如果我将<sch:p>标记作为<sch:pattern>的子标记，那么它会抛出NullPointerException，因为SchematronOutputType为null。 我尝试将<sch:p>作为<sch:schema>和<sch:rule>的孩子而没有任何问题，但XSD表示p元素可能是schema的孩子，{{ 1}}，phase。 我不确定问题是否在于PHSchematron的实施。 我认为xmlns：sch指向1.5 schematron XSD版本。

Answer 1

根据一般ISO Schematron规则进行测试，Schematron文档是正确的，targetNamespace属性除外。其中包含默认命名空间xmlns="..."也没有多大意义，因为所有元素都是前缀。

<强>的Schematron

<?xml version="1.0" encoding="UTF-8"?>
<sch:schema xmlns:sch="http://purl.oclc.org/dsdl/schematron" queryBinding="xslt2">   
   <sch:pattern id="sampleValidation">   
        <sch:title>PatternTitle</sch:title>
        <sch:p>A paragraph</sch:p>
        <sch:rule context="CCC">
            <assert test="normalize-space(.) and *">Source contains an empty element</assert>
        </sch:rule>  
   </sch:pattern>
</sch:schema>

然后，Schematron很好，但XML Schema存在许多问题。首先，XML Schema文档中的命名空间是不同的。 Schematron文件为http://purl.oclc.org/dsdl/schematron，而在XSD中为http://www.ascc.net/xml/schematron。这很可能是因为您使用的是旧版本的Schematron的旧版XML Schema。

拥有正确的命名空间应解决sch:p内sch:pattern不允许的问题。在XSD中修复名称空间问题后，仍然存在以下问题：

Attribute 'queryBinding' is not allowed to appear in element 'sch:schema'.
Attribute 'name' must appear on element 'sch:pattern'.
Invalid content was found starting with element '{"http://purl.oclc.org/dsdl/schematron":title}'. One of '{"http://purl.oclc.org/dsdl/schematron":p, "http://purl.oclc.org/dsdl/schematron":rule}' is expected.

所有这一切都可以通过修改XML Schema来解决，以下是一个有效的版本：
