Introduction to DocBook-4.5 XML DTD

The DocBook-4.5 XML DTD-4.5 package contains document type definitions for verification of XML data files against the DocBook rule set. These are useful for structuring books and software documentation to a standard allowing you to utilize transformations already written for that standard.

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

DocBook-4.5 XML DTD Dependencies

Required

libxml2-2.13.4 and UnZip-6.0 (or libarchive-3.7.7)

Installation of DocBook-4.5 XML DTD

[Note]

Note

The package source is distributed in zip format and requires unzip (or bsdunzip from libarchive). You should create a directory and change to that directory before unzipping the file to ease the removal of the source files after the package has been installed.

Install DocBook XML DTD by running the following commands as the root user: 

install -v -d -m755 /usr/share/xml/docbook/xml-dtd-4.5 &&
install -v -d -m755 /etc/xml &&
cp -v -af --no-preserve=ownership docbook.cat *.dtd ent/ *.mod \
    /usr/share/xml/docbook/xml-dtd-4.5

Create (or update) and populate the /etc/xml/docbook catalog file by running the following commands as the root user:

Configuring DocBook-4.5 XML DTD

Config Files

/etc/xml/catalog and /etc/xml/docbook

Configuration Information

[Caution]

Caution

Various BLFS packages request DocBook XML DTD version 4.x before V4.5, so the following step must be done for those packages to be built successfully.

The above installation creates the files and updates the catalogs. In order to utilize DocBook XML DTD V4.5 when any version 4.x is requested in the System Identifier, you need to add additional statements to the catalog files. If you have any of the DocBook XML DTD's referenced below already installed on your system, remove those entries from the for command below (issue the commands as the root user): 

for DTDVERSION in 4.1.2 4.2 4.3 4.4
do
  xmlcatalog --noout --add "public" \
    "-//OASIS//DTD DocBook XML V$DTDVERSION//EN" \
    "http://www.oasis-open.org/docbook/xml/$DTDVERSION/docbookx.dtd" \
    /etc/xml/docbook
  xmlcatalog --noout --add "rewriteSystem" \
    "http://www.oasis-open.org/docbook/xml/$DTDVERSION" \
    "file:///usr/share/xml/docbook/xml-dtd-4.5" \
    /etc/xml/docbook
  xmlcatalog --noout --add "rewriteURI" \
    "http://www.oasis-open.org/docbook/xml/$DTDVERSION" \
    "file:///usr/share/xml/docbook/xml-dtd-4.5" \
