HOWTO

# libxml
# ======
# There are several versions of libxml in this HOWTO.
# If you're installing it for something big like all of GNOME,
# it matters which major version you use.
# If you're installing it to be used by an Apache module or
# something specific like that, just make sure that the latest
# libxml2 is supported by it before you pick which one to use
# by going to the next branch down until you have a match.
#
# As this is written, 2.12.6 is the latest, but the latest covered below
# is 2.9.14 which was released in 2022

# Slackware 14.0: libxml2 2.8.0
# Slackware 14.1: libxml2 2.9.1
# Slackware 14.2: libxml2 2.9.4
# Slackware 15.0: libxml2 2.9.12
#
# And be sure to (drink your ovaltine) check 'patches' for updates
#
# MUCH, MUCH older versions of Slackware had a 'libxml' package for
# version 1.8.17

# libxml2 downloads (no longer at ftp.xmlsoft.org)
# http://www.xmlsoft.org/ (old site, redirects to GitLab)
# GitLab libxml2 Releases
# Read-only mirror of GitLab repository at Github
# libxml2 Reference Manual
# Slackware 15.0 libxml2 package source
# https://pkgs.org/search/?q=libxml2

# If you have a libxml (1.x or 2.x) that's installed under /usr/local, cd
# into it's source and run 'make uninstall' (as root) before proceeding
# here.  If you don't have the source, download it, run configure (as shown
# below) and then run 'make uninstall' (as root).  You can also run this to
# remove most files for old versions (and don't forget to remove source and
# tarballs too):
su
find /usr/local/lib -type f -name "libxml2.so.*" -exec rm {} \;
find /usr/lib -type f -name "libxml2.so.*" -exec rm {} \;
find /usr/local/doc -type d -name "libxml2-*" -exec rm -r {} \; 2> /dev/null
find /usr/doc -type d -name "libxml2-*" -exec rm -r {} \; 2> /dev/null
find /usr/share/doc -type d -name "libxml2-*" -exec rm -r {} \; 2> /dev/null
test -d /usr/local/include/libxml2 && rm -r /usr/local/include/libxml2
test -d /usr/include/libxml2 && rm -r /usr/include/libxml2
exit
