xslt range
Assuming the ranges don't overlap, you could transform the list of ranges into
a sorted binary tree:

<range from="988" to="8197">
  <range to="1036">
    <range to="1009">
      <range from="988" to="989"/>
      <range from="1008" to="1009"/>
    <range from="1014">
      <range from="1014" to="1014"/>
      <range from="1025" to="1036"/>
  <range from="1038">
    <range to="1116">
      <range from="1038" to="1103"/>
      <range from="1105" to="1116"/>
    <range from="1118">
      <range to="4150">
        <range from="1118" to="1119"/>
        <range from="4150" to="4150"/>
      <range from="8194" to="8197"/>

which gives O(log N) range tests rather than O(N) range tests. Then you have
to find out whether a recursive function to navigate the tree is slower by a
sufficient factor to kill any advantage in the number of tests being lower for
large N.
