Chapter 8. Sorting Things Out

Sometimes nodes don’t come to you in a convenient order. XSLT’s sort instruction element allows you to sort nodes in alphabetical or numerical order. You can also use sort to sort nodes in ascending (a, b, c) or descending (z, y, x) order.

This chapter walks you through a brief exploration of sort. You can also read about sorting in Section 10 of the XSLT specification. I’ll start, as usual, with a simple example.

Simple Ascending Sort

If you look at Example 8-1, the document europe.xml in examples/ch08, you’ll notice that the European states are not listed in alphabetical order.

Example 8-1. Unalphabetized European countries

<?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet href="pretty.xsl" type="text/xsl"?> <europe> <state>Belgium</state> <state>Germany</state> <state>Finland</state> <state>Greece</state> <state>Ireland</state> <state>Luxembourg</state> <state>Portugal</state> <state>Spain</state> <state>Andorra</state> <state>Belarus</state> <state>Monaco</state> <state>Sweden</state> <state>United Kingdom</state> <state>Austria</state> <state>Malta</state> <state>Vatican City</state> <state>Bulgaria</state> <state>Bosnia-Herzegovina</state> <state>Cyprus</state> <state>France</state> <state>Estonia</state> <state>Italy</state> <state>Hungary</state> <state>Latvia</state> <state>Ukraine</state> <state>Lithuania</state> <state>Moldova</state> <state>Denmark</state> <state>Poland</state> <state>Romania</state> <state>Slovenia</state> <state>The ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
