XPointer tutorial

"Child sequence" locates an element by stepwise navigation using a sequence of integers separated by slashes (/). This sequence may start with '/1' (because you may have only one document element) or a bare name. Each integer n locates the nth child of the previously located element. The example below selects the 3rd child of the 2nd child of the document element.

XPointer: /1/2/3

XPointer (alternative): xpointer(/*[1]/*[2]/*[3])

<AAA>
   <BBB myid="b1" bbb="111">
     Text in the first element BBB.</BBB>
   <BBB myid="b2" bbb="222">
      Text in another element BBB.
     <DDD ddd="999">
       Text in more nested element.</DDD>
     <DDD ddd="888">
       Text in more nested element.</DDD>
     <DDD ddd="777">
       Text in more nested element.</DDD>
   </BBB>
   <CCC ccc="123" xxx="321">
     Again some text in some element.</CCC>
