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

Question

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

我希望从"道德"开始获取内部文本,包含"和",并在标题节点中以"同意"结束.

一种可能的方式:

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

该ends-with()功能是XPath 2.0.在XPath 1.0中,可以使用substring()和替换它string-length().这是等效的XPath 1.0(为了便于阅读而包装):

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