How can I tell what version of libxml2 and libxslt are installed on OS X?

Question

I'm trying to find out what version I currently have installed. OS X Mountain Lion (10.8.2)

Thanks in advance!

On my 10.8.3 system it's 2.2:

> ls -l /usr/lib/libxml*
-rwxr-xr-x  1 root  wheel  2390032 Mar  2 17:18 /usr/lib/libxml2.2.dylib*
lrwxr-xr-x  1 root  wheel       15 Mar  2 17:21 /usr/lib/libxml2.dylib@ -> libxml2.2.dylib

Simple enough. Thanks! I was thinking of it in more of a man page or -v/--versions manner, but this makes sense, too. – Monroemonroy

I'm pretty sure that means it's lbxml2 version 2.something. Not very useful – Sandstorm

It's libxml version 2.2. – Karlenekarlens

Another option is to run xmllint and xsltproc with the --version flag:

$ xmllint --version
xmllint: using libxml version 20900
   compiled with: Threads Tree Output Push Reader Patterns Writer SAXv1 FTP HTTP DTDValid HTML Legacy C14N Catalog XPath XPointer XInclude ISO8859X Unicode Regexps Automata Expr Schemas Schematron Modules Debug Zlib
$ xsltproc --version
Using libxml 20900, libxslt 10128 and libexslt 817
xsltproc was compiled against libxml 20900, libxslt 10128 and libexslt 817
libxslt 10128 was compiled against libxml 20900
libexslt 817 was compiled against libxml 20900

This means I'm running libxml2 2.9.0, libxslt 1.1.28, and libexslt 0.8.17.

xmllint --version works on Ubuntu linux, too. – Clough

Answer 3

Not a complete answer, the real version number can be found looking at include xmlversion.h found inside /usr/include/libxml2/libxml:

Mac-mini-de-Vincent:libxml Vincent$ grep -Ri "LIBXML_DOTTED_VERSION" xmlversion.h
xmlversion.h:#define LIBXML_DOTTED_VERSION "2.9.0"

So on my system (10.9.1), the libxml2 version is 2.9.0.

Hi Vincent, what if I don't have the xmlversion.h file? I tried doing "find /usr -name xmlversion.h" and it did not return anything. Thanks – Mockery

@rockhammer, then you need to install the libxml2-devel package. – Cower

@Mockery If you are using Xcode on a Mac, then try find /Applications/Xcode.app -name xmlversion.h. It will be found in one of the embedded SDKs. – Lancey

In 10.8.5:

$ /usr/bin/xmllint --version
/usr/bin/xmllint: using libxml version 20708
   compiled with: Threads Tree Output Push Reader Patterns Writer SAXv1 FTP HTTP DTDValid
HTML Legacy C14N Catalog XPath XPointer XInclude ISO8859X Unicode Regexps Automata Expr
Schemas Schematron Modules Debug Zlib 

$ /usr/bin/xsltproc --version
Using libxml 20708, libxslt 10126 and libexslt 815
xsltproc was compiled against libxml 20708, libxslt 10126 and libexslt 815
libxslt 10126 was compiled against libxml 20708
libexslt 815 was compiled against livxml 20708
