15. Accessing individual locations in location set

This tutorial is obsolete. Please, use the new one.

Description

Similarly to accessing nodes in XPath's node-sets, the individual locations in XPointer's location-sets can be accessed using square brackets [ ].



Node-type locations
XPointer: xpointer(//AAA/BBB[2])

 <AAA>
   <BBB bbb="111">
     Text in the first element BBB.</BBB>
   <BBB bbb="222">
     Text in another element BBB.
     <DDD ddd="999">
       Text in more nested element.</DDD>
   </BBB>
   <CCC ccc="123" xxx="321">
     Again some text in some element.</CCC>
 </AAA>
  • X marks point (zero width)
  • This style marks the container node.
  • This style marks resulting locations.
  • X marks collapsed range (zero width)


Range-type locations
XPointer: xpointer(string-range(//*,'element')[3])

 <AAA>
   <BBB bbb="111">
     Text in the first element BBB.</BBB>
   <BBB bbb="222">
     Text in another element BBB.
     <DDD ddd="999">
       Text in more nested element.</DDD>
   </BBB>
   <CCC ccc="123" xxx="321">
     Again some text in some element.</CCC>
 </AAA>
  • X marks point (zero width)
  • This style marks the container node.
  • This style marks resulting locations.
  • X marks collapsed range (zero width)
