Note that:

• XPath "//p" is used to by-pass the layers to tables used for the Web page setup.
• My paragraph level blocks are "//p|//ul|//pre", so do not misuse them.
• Margins and spaces can be easily adjusted. But watch out "//pre" blocks.
• Only a limited number of xhtml tags are supported here. But it's easy to add more to it.

Process Instructions

• Copy *.xhtml and book.css into a directory on Web server. Web publishing is done.
• Run "xalan -in *.xhtml -xsl book_fo.xsl -out *.fo". This will produce one FO file per chapter.
• Open toc.fo, append at the end with "page-sequence" elements from other *.fo files, and name the final file as toc_expanded.fo.
• Run "fop toc_expanded.fo toc_expanded.pdf". PDF pusblishing is done.
• Of course, I have automated this process with a perl program.
