libxmldiff aims at providing efficient diff on XML files (C library)
Features are :
- Detection of modified items, added items, removed items
- Not sensitive to item position changes (based on a id).
- Designed to support large XML files (about 100 Mo). For larger files, treat these files with XML Pre Diff Tool would be a good idea.
- Basic XML manipulation (XSLT, Deletion,...)
- Scripting abilities
- Simple to use

libxmldiff comes with a command line xmldiff exposing all the features.
If you are searching for a GUI, please take a look at xmlTreeNav (https://github.com/rpeyron/xmltreenav)
See prebuilt binary packages in release tab for Windows.
PPA repository for Ubuntu : ppa:rpeyron/ppa
sudo apt-add-repository ppa:rpeyron/ppa
Other OSes should build the package (see below).
libxmldiff depends on :
- libxml2 (http://xmlsoft.org/)
libxmldiff is a standard autotools project :
./configure
make
If you get some problems, a bootstrap file is provided to rebuild all autotools.
You may install dependancies on debian systems by :
# Build dependancies
sudo apt-get install pkg-config libxml2-dev libxslt-dev autotools-dev automake autoconf
# Run dependancies
sudo apt-get install libc6 libxml2 libxslt1.1
Windows Build is done with Visual Studio Community Edition. Please use the latest version in build/ (older vc version are not maintained)
To build with msys2/mingw64:
msys2 -mingw64
pacman -S mingw-w64-x86_64-autotools
pacman -S mingw64/mingw-w64-x86_64-libxml2 mingw-w64-x86_64-libxslt
./configure
make
make install
Note: the build with msys2 won't be statically linked, so if you want to use it outside the msys2 environment, you will need to collect the required DLL to identify with:
ldd src/xmldiff.exe | grep mingw
A developer documentation is available on the github pages
Contributions are welcome. You may use GitHub issues tracker for issues, or GitHub Pull Requests.

xmldiff - diff two XML files. (c) 2004-2006 - Rémi Peyronnet
Syntax : xmldiff action [options] <parameters>
Actions
- diff <before.xml> <after.xml> <output.xml>
- merge <before.xml> <after.xml> <output.xml>
- xslt <style.xsl> <input.xml> <output.xml> [param='value']
- recalc <before.xml> <after.xml>
- execute <script.xds> (xds = list of these commands)
- load <filename> <alias>
- save <filename> <alias>
- close <alias> / discard <alias> (same as close without saving)
- flush
- options
- print <string>
- delete <from alias> <xpath expression>
- dup(licate) <source alias> <dest alias>
- rem(ark),#,--,;,// <remark>
- print_configuration
- ret(urn) <value>
Global Options :
--auto-save yes : Automatically save modified files
--force-clean no : Force remove of blank nodes and trim spaces
--no-blanks yes : Remove all blank spaces
--pretty-print yes : Output using pretty print writer
--optimize no : Optimize diff algorithm to reduce memory (see doc)
--use-exslt no : Allow the use of exslt.org extended functions.
--savewithxslt yes : Save with <xsl:output> options the results of XSLT.
--verbose 4 : Verbose level, from 0 (nothing) to 9 (everything).
Diff Options :
--ids '@id,@value' : Use these item to identify a node
--ignore '@ignore,..': Ignore differences on these items
--diff-only no : Do not alter files, just compare.
--keep-diff-only no : Keep only different nodes.
--before-values yes : Add before values in attributes or text nodes
--sep | : Use this as the separator
--encoding none : Force encoding
--tag-childs yes : Tag Added or Removed childs
--merge-ns yes : Create missing namespace on top of document
--diff-ns http://... : Namespace definition, use no to disable
--diff-xmlns diff : Alias to use, use no to disable
--diff-attr status : Name of attribute to use (should not be used in docs)
Output is a merge of the two files, with a status indicating if the node is modified, added, removed, or if a child is modified (please notice the diff:status attribute). A identifier can be used to compare similar items. If none is provided, comparison is done on identical nodes names by the order of appearance.
