       <BookRef>The Complete Reference - Javascript</BookRef>

    </References>
  </Chapter>
</Chapters> 

I am trying to list - all the containing HTML word using /Chapters/Chapter/References[BookRef contains text 'HTML']/BookRef

But all are being displayed...!! What will be the XQuery to retrieve the same?

Answer 1

Try the following one:

/Chapters/Chapter/References/BookRef[. contains text 'HTML']

Otherwise, all References nodes will be returned that have a BookRef node containing HTML , and the following step will return all BookRef nodes (ie, you lose the information which of the BookRef nodes had the searched token).

Answer 2

您要 ：

/Chapters/Chapter/References/BookRef[contains(., 'HTML')]

Answer 3

使用XPath = /Chapters/Chapter/References/BookRef[contains(., 'HTML')]
