XSL FO Sample Copyright © 1996-2005 Antenna House, Inc. All rights reserved. Printing program source code Generally, monospace font is used when printing the source code written by C or Java. Also, as white space code has an important meaning, we cannot discard it when printing the source code. In such case, by setting the property of font-family="monospace" white-space="pre" to fo:block, white space in the code can be printed easily in monospace mode, without ignored. The following example is made only by pasting the program code to fo:block with no change. void main(void) { printf("Hello, XML world!"); }
