## Installation of DocBook XSL Stylesheets

First, fix a problem that causes stack overflows when doing recursion:

    patch -Np1 -i ../docbook-xsl-nons-1.79.2-stack_fix-1.patch

If you downloaded the optional documentation tarball, unpack it with the following command:

    tar -xf ../docbook-xsl-doc-1.79.2.tar.bz2 --strip-components=1

BLFS does not install the required packages to run the test suite and provide meaningful results.

Install DocBook XSL Stylesheets by running the following commands as the `root` user:

    install -v -m755 -d /usr/share/xml/docbook/xsl-stylesheets-nons-1.79.2 &&

    cp -v -R VERSION assembly common eclipse epub epub3 extensions fo        \
             highlighting html htmlhelp images javahelp lib manpages params  \
             profiling roundtrip slides template tests tools webhelp website \
             xhtml xhtml-1_1 xhtml5                                          \
        /usr/share/xml/docbook/xsl-stylesheets-nons-1.79.2 &&

    ln -s VERSION /usr/share/xml/docbook/xsl-stylesheets-nons-1.79.2/VERSION.xsl &&

    install -v -m644 -D README \
                        /usr/share/doc/docbook-xsl-nons-1.79.2/README.txt &&
    install -v -m644    RELEASE-NOTES* NEWS* \
                        /usr/share/doc/docbook-xsl-nons-1.79.2

If you downloaded the optional documentation tarball, install the documentation by issuing the following command as the `root` user:

    cp -v -R doc/* /usr/share/doc/docbook-xsl-nons-1.79.2

## Configuring DocBook XSL Stylesheets

###

#### Config Files

`/etc/xml/catalog`

###

#### Configuration Information

### Note

If you are installing the current version of docbook-xsl-nons over a previous version of docbook-xsl, then remove the old rewrite entries in the catalog as the `root` user:

    sed -i '/rewrite/d' /etc/xml/catalog

Create (or append) and populate the XML catalog file using the following commands as the `root` user:

    if [ ! -d /etc/xml ]; then install -v -m755 -d /etc/xml; fi &&
    if [ ! -f /etc/xml/catalog ]; then
        xmlcatalog --noout --create /etc/xml/catalog
    fi &&

    xmlcatalog --noout --add "rewriteSystem" \
               "https://cdn.docbook.org/release/xsl-nons/1.79.2" \
               "/usr/share/xml/docbook/xsl-stylesheets-nons-1.79.2" \
        /etc/xml/catalog &&

    xmlcatalog --noout --add "rewriteURI" \
               "https://cdn.docbook.org/release/xsl-nons/1.79.2" \
               "/usr/share/xml/docbook/xsl-stylesheets-nons-1.79.2" \
        /etc/xml/catalog &&

    xmlcatalog --noout --add "rewriteSystem" \
               "https://cdn.docbook.org/release/xsl-nons/current" \
               "/usr/share/xml/docbook/xsl-stylesheets-nons-1.79.2" \
        /etc/xml/catalog &&

    xmlcatalog --noout --add "rewriteURI" \
               "https://cdn.docbook.org/release/xsl-nons/current" \
               "/usr/share/xml/docbook/xsl-stylesheets-nons-1.79.2" \
        /etc/xml/catalog &&

    xmlcatalog --noout --add "rewriteSystem" \
               "http://docbook.sourceforge.net/release/xsl/current" \
               "/usr/share/xml/docbook/xsl-stylesheets-nons-1.79.2" \
        /etc/xml/catalog &&

    xmlcatalog --noout --add "rewriteURI" \
               "http://docbook.sourceforge.net/release/xsl/current" \
               "/usr/share/xml/docbook/xsl-stylesheets-nons-1.79.2" \
        /etc/xml/catalog

Occasionally, you may find the need to install other versions of the XSL stylesheets as some projects reference a specific version. One example is BLFS-6.0, which required the 1.67.2 version. In these instances you should install any other required version in its own versioned directory and create catalog entries as follows (substitute the desired version number for `<version>`):

    xmlcatalog --noout --add "rewriteSystem" \
               "http://docbook.sourceforge.net/release/xsl/<version>" \
               "/usr/share/xml/docbook/xsl-stylesheets-<version>" \
        /etc/xml/catalog &&

    xmlcatalog --noout --add "rewriteURI" \
               "http://docbook.sourceforge.net/release/xsl/<version>" \
               "/usr/share/xml/docbook/xsl-stylesheets-<version>" \
        /etc/xml/catalog
