通过XPath根据条件获取XML值

Question

Below is my XML:

<bookstore>
   <book>
      <title>Python</title>
      <price>29.99</price>
   </book>
   <book>
      <title>XML</title>
      <price>29.99</price>
      <feature>
           <description>Learn XML</description>
      </feature>
   </book>
</bookstore>

If the description "Learn XML" is matched, then it should return the title "XML" .

Answer 1

Try this XPath

//description[text() = 'Learn XML']/../../title

It matches all description elements with text() content of "Learn XML" and gets its title .

Answer 2

This XPath,

//book[feature/description="Learn XML"]/title

will return title elements of books whose feature/description is "Learn XML" .
