Using XSL-FO You've already seen a short XSL-FO example, but in fact, XML documents are only rarely formatted by directly using formatting objects as in the example you've seen because the process becomes too complex.

What usually happens is that you take an XML document (with the extension.xml), run it through an XSLT processor to create a new XML document that uses XSL-FO (with the extension.fo), and then use an XSL-FO processor to create the formatted display document (with the extension.pdf in today's discussion). You do things this way because any document except a nontrivial one has many paragraphs of text or data, and to format each one by hand would be a time-consuming process. In fact, XSLT was originally developed for formatting XML documents by using XSL-FO objects. Since then, being able to access XML data without writing software using XSLT in itself has become so powerful that XSLT has outstripped XSL-FO in popularity. For example, say that you want to use XSL-FO to format the XML document with state data that you worked with yesterday.

Let's use that document today, renaming it ch10_01.xml, as shown in Listing 10.1. Example 10.1. Download Free Program For Voyage 200 Software Store here.

Let's take a look at the XSLT style sheet that will do that. Using XSLT to Create an XSL-FO Document Although you could format ch10_01.xml by hand, it's easier to use an XSLT style sheet to do so.

Listing 10.2 contains the style sheet ( ch10_02.xml) that you're going to use in this example. In this case, you're just going to extract the state data from ch10_01.xml and present that data in a list form, using 18-point font. Example 10.2. An XSL Document That Adds XSL-FO Formatting ( ch10_02.xsl) Name: Population (people): Capital: Bird: Flower: Area (square miles): Today you'll see how ch10_02.xsl works and what it does.

The first step, as described in the following section, is to put this style sheet to work and create the XSL-FO document. Creating an XSL-FO Document by Using an XSLT Style Sheet You're ready to create an XSL-FO document, which you can call ch10_03.fo. This document is the one you'll feed into an XSL-FO processor to create a formatted PDF document that will display the data from the XML document ch10_01.xml. To create ch10_03.fo, you only need to apply the XSLT style sheet ch10_02.xsl to the XML document ch10_01.xml. For example, if you have Java 1.4 or later installed, you can use the Java file ch09_05.class that is in the code download area for this book that you used yesterday, like this:%java ch09_05 ch10_01.xml ch10_02.xsl ch10_03.fo This creates ch10_03.fo, which is ch10_01.xml formatted with XSL-FO. Listing 10.3 presents ch10_03.fo; note the length of it compared to the original XML document, ch10_01.xml, and you can see why it's a good idea to use XSLT to create XSL-FO documents if you're working with data of any significant length. Example 10.3.
