XPointer functions

"range-to" Function

For each location in the context, range-to returns a range

Example: Locates the range from the start point of the element with 
         ID "chap1" to the end point of the element with ID "chap2"
         xpointer(id("chap1")/range-to(id("chap2")))

"string-range" Function

Returns a location set with one range for every nonoverlapping match to the search string. The match operation is case-sensitive.

Examples:

  string-range(/,"John")
  string-range(/,"John")[2]
  string-range(//STUDENT[3]/NAME, "John")[3]
  string-range(//STUDENT[3]/NAME, "John",6,2)[3]
