使用Schematron识别xml文本元素 [英] Identify xml text elements with Schematron

问题描述

是否有可能在XPath中制定一条规则来标识像这样的xml元素:

Is it possible to make a rule in XPath which identifies xml elements like this one:

<A>something...<A>

?

我正在使用Schematron，我需要指定某些元素不能像示例中的那样具有子元素，这就是为什么我需要识别它们的原因.

I am using Schematron and I need to specify that some elements must not have children like the one in the example, that's why I need to identify them.

预先感谢

推荐答案

对于以下输入:

<?xml version="1.0" encoding="utf-8"?>
<root>
  <a>Only Text</a>
  <a><b>Child node</b></a>  
  <a><b>Child node</b>Mixed content</a>
</root>

这些Schematron规则应执行您想要的操作:

These Schematron rules should do what you want:

<?xml version="1.0" encoding="UTF-8"?>
<iso:schema xmlns:iso="http://purl.oclc.org/dsdl/schematron">
<iso:pattern id="children tests">
    <iso:rule context="a">
        <iso:assert test="child::node()">
            Element has nodes
        </iso:assert>
        <iso:report test="child::*">
            Element has child elements
        </iso:report>
        <iso:assert test="empty(child::text())">
            Element has text
        </iso:assert>
        <iso:report test="child::text() and empty(child::*)">
            Element has only text
        </iso:report>               
    </iso:rule>
</iso:pattern>
</iso:schema>
