如何在XPath中使用starts-with()、contains()和ends-with()来查找xml节点innertext?在 XPATH 1.0 中 [英] How to use starts-with() , contains() and ends-with() in XPath to find the xml node innertext? in XPATH 1.0

问题描述

<ArticleBackmatter>
   <Heading>Ethical standards and patient consent</Heading>
   <Heading>Ethical standards and patient</Heading>
   <Heading>standards and patient consent</Heading>
</ArticleBackmatter>

我想在 Heading 节点中获取以 "Ethical" 开头、包含 "and" 并以 "consent" 结尾的内部文本.

I want to get the inner text with start from "Ethical" , contains "and " and end with "consent" in the Heading node.

推荐答案

一种可能的方式:

//Heading[starts-with(., 'Ethical') and ends-with(., 'consent')]

ends-with() 函数是 XPath 2.0.在 XPath 1.0 中，可以使用 substring() 和 string-length 替换().这是等效的 XPath 1.0(为了可读性而包装):

The ends-with() function is XPath 2.0. In XPath 1.0, it can be replaced using substring() and string-length(). Here is the equivalent XPath 1.0 (wrapped for readability):

//Heading[
            starts-with(., 'Ethical') 
                and 
            'consent' = substring(., string-length(.) - string-length('consent') +1)
         ]
