Example
The following example demonstrates the results of invoking the string-length()
function against various argument types. Here’s the XML document we’ll use for our example:
<?xml version="1.0"?> <test> <p>This is a test XML document used by several of our sample stylesheets.</p> <question> <text>When completed, the Eiffel Tower was the tallest building in the world.</text> <true>You're correct! The Eiffel Tower was the world's tallest building until 1930.</true> <false>No, the Eiffel Tower was the world's tallest building for over 30 years.</false> </question> <question> <text>New York's Empire State Building knocked the Eiffel Tower from its pedestal.</text> <true>No, that's not correct.</true> <false>Correct! New York's Chrysler Building, completed in 1930, became the world's tallest.</false> </question> </test>
