1 DocBook Assembly Stylesheets
2 ==============================
5 This directory provides XSL stylesheets for working with
6 DocBook assemblies. It is intended to enable working with
7 <topic> and <assembly> elements, as defined in DocBook 5.1
10 This kit currently supports most features of an assembly.
11 See the "Unsupported Features" section below for details
12 of what is not currently supported. These more advanced
13 features will be supported as it is further developed.
16 Content of this directory:
17 --------------------------
18 topic-maker-chunk.xsl - stylesheet to modularize an existing DB5 document.
19 topic-maker.xsl - imported by topic-maker-chunk.xsl.
20 assemble.xsl - stylesheet to process an <assembly> into a document.
23 The toolkit consists of an assemble.xsl XSL stylesheet
24 to process a DocBook <assembly> element to convert it
25 to an assembled DocBook 5 document ready to be formatted.
26 This stylesheet will enable users to structure a book from
29 To make it easy to initially create a modular book, this
30 kit also includes a topic-maker-chunk.xsl XSL stylesheet
31 to break apart an existing DocBook 5 book into modular
32 files, and also create the associated <assembly> document.
33 Then you can run the assemble.xsl stylesheet to put it
34 back together as a single DocBook document.
37 To create an assembly and topic files from a book or article document
38 =======================================================================
40 If you have an existing DocBook 5 book or article document,
41 you can convert it to an assembly and a collection of
42 modular topic files. If you want to convert a DocBook 4
43 document, you must first convert it to version 5.
45 For example, to disassemble a DocBook 5 book document named book.xml:
48 --stringparam assembly.filename myassembly.xml \
49 --stringparam base.dir topics/ \
50 topic-maker-chunk.xsl \
53 This command will result in a master assembly file named
54 'myassembly.xml' with a root element of <assembly>, containing
55 a single <structure> element. It will also break up the
56 content of the book into modular chunks that are output
57 to the 'topics/' subdirectory as specified in the 'base.dir'
62 The name of the assembly file is set by the stylesheet param
63 named 'assembly.filename', which should include the filename suffix.
65 Modular files are output to the directory location specified
66 by the 'base.dir' parameter. If you want them in the current
67 directory, then don't set that param.
69 By default the assembly element is output to the current
70 directory, *not* into base.dir with the modular files.
71 The <resources> element in the assembly has its xml:base
72 attribute set to the value of 'base.dir', so that it is
73 added to the paths to the modular files when processed.
74 If you set the stylesheet param 'manifest.in.base.dir'
75 to 1, then the assembly file is created in the base.dir
76 directory and the xml:base attribute is omitted (since
77 they are together in the same directory).
79 If you want the assembly file in 'base.dir' instead of
80 the current directory, then set the stylesheet param
81 'manifest.in.base.dir' to 1.
83 The stylesheet chunks a document into modules at the
84 same boundaries as the chunking XHTML stylesheet, because
85 it reuses many of the chunking stylesheet templates.
86 You can alter the chunking behavior with the same options
87 as for XHTML chunking.
89 For example, the stylesheet will chunk sections into topics
90 down to section level 3 by default. To change that level,
91 change the stylesheet param 'chunk.section.depth' to
94 Finer control of chunking can be achieved by using
95 the <?dbhtml stop-chunking?> processing instruction in
98 Many modular elements retain their original element name,
99 such as glossary, bibliography, index, and such. By default, the
100 stylesheet converts chapter, article, preface and section elements
101 into <topic> modules. To change that list of
102 converted element names, alter the stylesheet param named
103 'topic.elements'. If that param is empty, then no elements
104 will be converted to <topic>, so they will all retain their
105 original element names.
107 Modular filenames use the same naming scheme as the chunking
108 XHTML stylesheet, and supports the same file naming options such as
109 the param 'use.id.as.filename', which is set to 1 by default.
110 Note that the stylesheet param 'html.ext' is set to '.xml'
111 because it is producing modular XML files, not HTML files.
113 Root element conversion
114 ------------------------
115 By default, the root element of the original document is
116 also converted to a module, and <structure> gets a resourceref
117 attribute to reference it. If you set the stylesheet
118 param 'root.as.resourceref' to zero, then the root element
119 is handled differently, as described as follows.
121 If the structure element does not have a resourcref
122 attribute, the root element is constructed rather
123 than copied from a resource. The structure element must
124 have a renderas attribute (or its child output element must
125 have such) to select the output root element name.
127 Any content between the root element start tag and the
128 first module is put into a resource with the original
129 root element. To pull this content in, the first
130 module in the structure points to this resource but
131 uses a contentonly="yes" attribute. The effect of
132 that attribute is to pull in all content *except*
133 the root element of that resource.
135 In general, if you have content that does not logically
136 have its own container element, you can put the content
137 into a suitable container element and then deselect the
138 container element upon assembly with the contentonly="yes"
139 attribute. That attribute can also be used to avoid
140 pulling in a resource's xml:id when you want to change it.
143 To process an <assembly> into an assembled DocBook document
144 ==============================================================
146 To convert an <assembly> and its associated modular
147 files into a single DocBook document, process
148 your assembly document with the assemble.xsl stylesheet.
149 You should then be able to process the resulting
150 document with a DocBook XSL formatting stylesheet.
155 Useful params in assemble.xsl
156 -----------------------------
157 The $root.default.renderas param sets the name of the
158 root element of the assembled document, if it is not
159 otherwise specified with @renderas. Its default value
162 The $topic.default.renderas param sets the name of the
163 output element for any topic element included in the
164 assembly, if it is not otherwise specified with
165 @renderas. It's default value is 'section'.
167 The $structure.id param lets you specify at runtime
168 the id value of the structure you want to reassemble.
169 This is only necessary if you have more than one
170 structure element in your assembly.
172 The $output.type param also lets you specify at runtime
173 which structure element to process. In this case,
174 the value should match on an @type attribute on
175 the structure element.
177 The $output.format param lets you specify at runtime
178 which of several possible output formats are being generated.
179 The param value is compared to the @format
180 attribute on <output> elements to select specific properties
186 -----------------------
188 The transforms and transform elements are currently ignored
189 by the assembly stylesheet.
191 The relationships and relationship elements are currently
192 ignored by the assembly stylesheet.
194 The filterin and filterout elements are not currently
