Sorting XML Data
Now try sorting the data by applying an instruction to sort by value of the
TITLE element. Download and save this file
and modify your book.xml file with this line
<?xml-stylesheet type="text/xsl" href="book3.xsl"?>
Reload book.xml
The relevant XSL instruction is:
<xsl:sort select="TITLE"/>
Try sorting by the name of the author and remember that where XML is concerned,
lowercase author is not the same as uppercase AUTHOR.
The correct syntax must be adhered to, or your code will fail. THE XML elements
were written in uppercase, although, because XML is extensible, I could have
used lowercase. Note that this is not to be confused with writing XHTML tags,
which must be written lowercase. Go here
for more on this.
