We have seen XSLT used at a high level in other chapters, now we'll look at the details of how it works. But be aware that the full details on XSLT could fill a book[1] and we don't cover them all here. The objective of this chapter is to provide a basic understanding for the way that XSLT stylesheets cause XML documents to be processed.
[1] The one we recommended is Definite XSLT and XPath by Ken Holman, published in this series.
