Everyone seems to be talking about Extensible Markup Language (XML) these days. You know how mothers are—I can’t even visit my relatives over the holidays without my mom broaching the topic of XML at Thanksgiving dinner. Yes, XML has become quite a buzzword, but Extensible Stylesheet Language Transformations (XSLT) is the power that takes all this XML and turns it into something useful and flexible.
XSLT is a language used to transform XML documents into something new. It can take one XML document and output that document’s information into a completely different structure or turn XML into an HTML document for viewing on the Web. XSLT isn’t a general-purpose programming language, such as Java or Visual Basic; its focus is solely on transforming XML.
Before I get any farther along, I have to point out the “elephant in the room”—XSLT’s long-winded name. Who came up with that name anyway? I think the people responsible should be forced to say, “Extensible Stylesheet Language Transformations,” aloud ten times and hope their tongues don’t fall off! XSLT’s full name may be a mouthful, but this book carves up each piece of XSLT into manageable, chewable morsels.
