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

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

Answer 1

One possible way:

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

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)
         ]
