Outputting the Results
So, how do you get output from the XSL processor? The answer depends on how you invoke the processor. For our purposes, let’s assume that this is a static style sheet stored in a file called invoice.xsl. Now, you can attach the style to the XML source document in one of two ways. The easiest is to include an <?xml-stylesheet> directive in the source document. If you leaf back to Listing 2.1, you’ll notice the following statement at the top of the listing:
<?xml-stylesheet type="text/xsl" href="invoice.xsl"?>
When the XML parser sees this line, invoice.xsl is loaded and applied to the source document. The resulting output is shown in Listing 2.4.
