The latest versions of libxml2 can be found on the xmlsoft.org server ( FTP and rsync are available), there are also mirrors (France and Antonin Sprinzl also provide a mirror in Austria). (NOTE that you need both the libxml(2) and libxml(2)-devel packages installed to compile applications using libxml if using RPMs.)
You can find all the history of libxml(2) and libxslt releases in the old directory. The precompiled Windows binaries made by Igor Zlatovic are available in the win32 directory.
RPMs for x86_64 are available directly on xmlsoft.org, the source RPM will compile on any architecture supported.
Igor Zlatkovic is now the maintainer of the Windows port, he provides binaries.
OpenCSW provides Solaris binaries.
Steve Ball provides Mac Os X binaries.
The HP-UX porting center provides HP-UX binaries
Bull provides precompiled RPMs for AIX as patr of their GNOME packages
If you know other supported binary ports, please contact me.
Code from the GNOME GIT base libxml2 module, updated hourly libxml2-git-snapshot.tar.gz.
Docs, content of the web site, the list archive included libxml-docs.tar.gz.
I do accept external contributions, especially if compiling on another platform, get in touch with the list to upload the package, wrappers for various languages have been provided, and can be found in the bindings section
Libxml2 is also available from GIT:

Библиотека libxml2 для работы с XML-файлами
Программисту часто бывает нужно работать с XML-документами. Самой популярной библиотекой для этого является libxml2. Научимся ее подключать к своему проекту.
1. Что такое libxml2?
libxml2 — это библиотека для парсинга XML-документов. Это означает,что программист может искать и править отдельные атрибуты и значения в XML-документе.
Библиотека написана на языке Си, и, вследствие этого, переносима практически на все платформы (Unix, Windows, CygWin, Mac OS, RISC OS, OS/2, VMS, QNX, MVS и т.д.).
Кроме того, существуют привязки к языкам C++, Python, PHP5 и т.д.
Библиотека распространяется под MIT-лицензией, что делает эту библиотеку весьма популярной.
2. Загрузка библиотеки
Библиотеку libxml2 в формате готовых файлов можно загрузить на сайте: www.zlatkovic.com/projects/libxml/index.html
Нужно учесть, что файлы имеют зависимости, поэтому для выбора загружаемых файлов нужно их учитывать:
Мы видим, что в минимальном варианте нужно загрузить следующие пакеты:
Заходим на www.zlatkovic.com/pub/libxml/ и загружаем три архива:
Распаковываем эти архивы в папку с CodeBlocks. В каждом архиве содержатся папки bin (исполняемые модули), lib (статические библиотеки) и include (заголовочные файлы).
Цифры в названиях можно убрать для удобства:

How to install lxml on Windows
I’m trying to install lmxl on my Windows 8.1 laptop with Python 3.4 and failing miserably.
First off, I tried the simple and obvious solution: pip install lxml . However, this didn’t work. Here’s what it said:
So then I looked on this great and helpful thing called The Internet and a lot of people have the same error of needing libxml2 and libxlst . They recommend a guy called Christoph Gohlke’s page where he provides some sort of binary thingy for a bunch of packages. You can find it here (quicklink to the lxml part).
So after I gave up on trying to find libxml2 and libxslt for pip, I decided to go there, and found an absolute ton of downloads. I know I need a 64-bit one, but I have no idea which » cp » I need.
So an answer either giving me a solution on the pip method or the Gohlke index method would be great.

Or you can also go to Christoph’s Gohlke’s Python page and then download the right lxml file. (Generally since I use python 3.4 and I have a windows, I download the lxml-3.4.4-cp34-none-win32.whl)
Go to the folder it is in. Click in the background (so nothing is selected), then leftshift + rightclick at the same time and click on open command window. Then type C:/Python34/Scripts/pip install «NAME OF THE FILE YOU JUST DOWNLOADED.whl»
In this case it would be C:/Python34/Scripts/pip install «lxml-3.4.4-cp34-none-win32.whl»
Now hit enter. This worked well for me, and after you type the quote you can also press tab and it should fill the right one for you.
First, following the comments, I downloaded the lxml-3.4.2-cp34-none-win_amd64.whl file and tried to open it with a pip install , but it just told me it wasn’t a valid wheel file on my system or something.
Then, I downloaded the win_32 file and it worked! Maybe it’s because I have an Intel processor and AMD64 is, unsurprisingly, only for AMD processors.
Looks like today in 2018, lxml can be installed from PyPI:
These instructions are for Windows7 or Windows8 with Python3.4.
However, they should work for various versions as the releases of python and other respective prerequisites change/evolve:
Installing lxml
lxml is generally distributed through PyPI.
Most Linux platforms come with some version of lxml readily packaged, usually named python-lxml for the Python 2.x version and python3-lxml for Python 3.x. If you can use that version, the quickest way to install lxml is to use the system package manager, e.g. apt-get on Debian/Ubuntu:
For MacOS-X, a macport of lxml is available. Try something like
To install a newer version or to install lxml on other systems, see below.
Requirements
You need Python 2.7 or 3.4+.
Unless you are using a static binary distribution (e.g. from a Windows binary installer), lxml requires libxml2 and libxslt to be installed, in particular:
libxml2 version 2.9.2 or later.
libxslt version 1.1.27 or later.
We recommend libxslt 1.1.28 or later.
Newer versions generally contain fewer bugs and are therefore recommended. XML Schema support is also still worked on in libxml2, so newer versions will give you better compliance with the W3C spec.
To install the required development packages of these dependencies on Linux systems, use your distribution specific installation tool, e.g. apt-get on Debian/Ubuntu:
For Debian based systems, it should be enough to install the known build dependencies of the provided lxml package, e.g.
Installation
If your system does not provide binary packages or you want to install a newer version, the best way is to get the pip package management tool (or use a virtualenv) and run the following:
If you are not using pip in a virtualenv and want to install lxml globally instead, you have to run the above command as admin, e.g. on Linux:
To install a specific version, either download the distribution manually and let pip install that, or pass the desired version to pip:
To speed up the build in test environments, e.g. on a continuous integration server, disable the C compiler optimisations by setting the CFLAGS environment variable:
(The option reads «minus Oh Zero», i.e. zero optimisations.)
MS Windows
For MS Windows, recent lxml releases feature community donated binary distributions, although you might still want to take a look at the related FAQ entry. If you fail to build lxml on your MS Windows system from the signed and tested sources that we release, consider using the binary builds from PyPI or the unofficial Windows binaries that Christoph Gohlke generously provides.
Linux
On Linux (and most other well-behaved operating systems), pip will manage to build the source distribution as long as libxml2 and libxslt are properly installed, including development packages, i.e. header files, etc. See the requirements section above and use your system package management tool to look for packages like libxml2-dev or libxslt-devel . If the build fails, make sure they are installed.
Alternatively, setting STATIC_DEPS=true will download and build both libraries automatically in their latest version, e.g. STATIC_DEPS=true pip install lxml.
MacOS-X
On MacOS-X, use the following to build the source distribution, and make sure you have a working Internet connection, as this will download libxml2 and libxslt in order to build them:
Building lxml from dev sources
If you want to build lxml from the GitHub repository, you should read how to build lxml from source (or the file doc/build.txt in the source tree). Building from developer sources or from modified distribution sources requires Cython to translate the lxml sources into C code. The source distribution ships with pre-generated C source files, so you do not need Cython installed to build from release sources.
If you have read these instructions and still cannot manage to install lxml, you can check the archives of the mailing list to see if your problem is known or otherwise send a mail to the list.
Using lxml with python-libxml2
If you want to use lxml together with the official libxml2 Python bindings (maybe because one of your dependencies uses it), you must build lxml statically. Otherwise, the two packages will interfere in places where the libxml2 library requires global configuration, which can have any kind of effect from disappearing functionality to crashes in either of the two.
To get a static build, either pass the —static-deps option to the setup.py script, or run pip with the STATIC_DEPS or STATICBUILD environment variable set to true, i.e.
The STATICBUILD environment variable is handled equivalently to the STATIC_DEPS variable, but is used by some other extension packages, too.
Source builds on MS Windows
Most MS Windows systems lack the necessarily tools to build software, starting with a C compiler already. Microsoft leaves it to users to install and configure them, which is usually not trivial and means that distributors cannot rely on these dependencies being available on a given system. In a way, you get what you’ve paid for and make others pay for it.
Due to the additional lack of package management of this platform, it is best to link the library dependencies statically if you decide to build from sources, rather than using a binary installer. For that, lxml can use the binary distribution of libxml2 and libxslt, which it downloads automatically during the static build. It needs both libxml2 and libxslt, as well as iconv and zlib, which are available from the same download site. Further build instructions are in the source build documentation.
Source builds on MacOS-X
If you are not using macports or want to use a more recent lxml release, you have to build it yourself. While the pre-installed system libraries of libxml2 and libxslt are less outdated in recent MacOS-X versions than they used to be, so lxml should work with them out of the box, it is still recommended to use a static build with the most recent library versions.
How to solve “libxml2 missing package” error on “gem install ovirt-engine-sdk” on Windows?
I am trying to run gem install ovirt-engine-sdk on a Windows 10 machine and I am facing the following issue:
I have tried to :
install libxml2 on Windows
try with all the —without-libxml2-config , —without-libxml2-config , . parameters
uninstall and re-install Ruby, in order to try with other Ruby versions (my current ruby version is ruby 2.5.3p105 (2018-10-18 revision 65156) [x64-mingw32]
try more or less all the different answers I could find about related issues on Stack Overflow
I am running out of ideas so if someone could have any clue to get me out of this, that would be much appreciated!
Thank you so much!

I’m unfamiliar with ovirt-engine-sdk, and can’t find any information on their github to imply they support windows (it’s not guaranteed, especially for gems with native extensions). But we can definitely work around this particular error. To help show you how to deal with similar problems in the future, here’s my process to troubleshoot this.
The relevant portion is here (found by searching for the error message):
We can see it’s checking for an executable named xml2-config . According to the documentation for find_executable, it checks your path for that.
So, this means we need two things to fix this error:
The xml2-config executable
We need to add that to our path. It sounds like this is the step you’re missing.
You can download from here — Then add the entire bin folder to your path.
