There are several parameters that control numbering of chapter and section titles. By default, chapter titles are numbered but section titles are not. Appendix titles are numbered when in a book, but not numbered by default when in an article. In the DocBook XSL stylesheets, the number part of a title is called a label.
If you prefer to turn off chapter numbering, then set the
chapter.autolabel parameter to zero. If you also want to turn off appendix
numbering (A, B, C, etc.), then also set the
appendix.autolabel parameter to zero.
xsltproc --output myfile.html \ --stringparam chapter.autolabel 0 \ --stringparam appendix.autolabel 0 \ html/docbook.xsl myfile.xml
Chapter 3. Using a mouse 1. Basic mouse actions sect1 1.1 Left button sect2 1.2 Right button sect2 1.2.1 Context menus sect3 2. Selecting sect1 2.1 Click and drag 2.2 Double click
Notice that the section numbers do not include the chapter number by default, so section numbering starts over with each new chapter. If you prefer the section numbers to include the chapter number, then set the
section.label.includes.component.label parameter to 1. This assumes that you leave chapter
numbering turned on. For example:
xsltproc --output myfile.html \ --stringparam section.autolabel 1 \ --stringparam section.label.includes.component.label 1 \ html/docbook.xsl myfile.xml
This results in the following numbering style:
Chapter 3. Using a mouse 3.1. Basic mouse actions sect1 3.1.1 Left button sect2 3.1.2 Right button sect2 22.214.171.124 Context menus sect3 3.2. Selecting sect1 3.2.1 Click and drag 3.2.2 Double click
Section titles in an appendix will have the appendix letter instead of a chapter number.
You may want to limit the depth of sections that get a section number. If you have deeply nested sections, then the string of numbers in the section label can get quite long. Or perhaps you just want sections at levels 1 and 2 to be numbered, since any lower level sections aren't important enough to have a number label.
You can use the
section.autolabel.max.depth parameter to control which section levels get a number
label. If you set the parameter to 2, then only sections at levels 1
and 2 will have the label. The default value is 8, meaning all
section levels have numbering (if it is turned on).
