Transformation with XSLT and Perl
The XML Stylesheet Language Transformations (XSLT) specification describes an XML-based scripting language that can be used to create rules for transforming one XML format into another. In some cases you may wish to use XSLT instead of a Perl-based solution. You can still use Perl to interpret the XSLT rules, however. The XSLT specification is available online at http://www.w3.org/TR/xslt.
Example 7-3 reimplements part of the slide-show generator script introduced in Chapter 6, this time using XSLT. The example uses a slightly different version of the slide XML description language discussed there.
