I found a program someone wrote called sortxml that will prettify and sort XML files. It's written C#. Might be possible to run it on Linux also, or to find another similar program for Linux that will. I'd investigate further if it wasn't for the fact that I rarely work with XML files. https://github.com/kodybrown/sortxml https://github.com/kodybrown/sortxml You may be able to write a small wrapper script that does the following: For each filename passed as argument to your script you will run sortxml on it and store the result in a temporary file, then once you've done so for all files, you pass the sorted files to an existing merge tool such as for example meld, kdiff3 or vimdiff. Let's say that you name your script mergexml.bash and that you put it in ~/bin/. Then it should be possible to first git merge as usual but when a conflict arises in an XML file, you will run something like git mergetool -t ~/bin/mergexml.bash example.xml And your script will have simplified the process. For bonus points, you might write an unsortxml program that your script will call at the end to rearrange the nodes and attributes to be in the same order as they were in one of the original XML files -- the user would be prompted to select which of the original XML files to use for ordering the nodes and attributes. I haven't tested this of course, otherwise I'd probably have actual code to share for it but I think something like what I've outlined above should work.

Here's an extended example. mkdir -p ~/tmp/xml-merge-example cd !$ git init . cat > example.xml <<EOF <?xml version='1.0'?> <hurr durr='hello'/> <durr hurr='world'/> EOF git add . git commit -m "Initial commit." git checkout -b alternate-reality cat > example.xml <<EOF <?xml version='1.0'?> <durr hurr='world'/> <hurr durr='hello'/> <foo reality='alternate'/> EOF git add . git commit -m "Alternate reality." git checkout master sed -i '' -e 's/hello/foo/' -e 's/world/bar/' example.xml git add . git commit -m "Hello foo to the world bar." git merge alternate-reality The attempted merge will result in the following: Auto-merging example.xml CONFLICT (content): Merge conflict in example.xml Automatic merge failed; fix conflicts and then commit the result. For a quick PoC, let's create a little script that will echo the arguments that was passed to it and then exit with failure. The real script would work as outlined in the parent comment and would exit with success at the end as long as the merge worked out. The t argument to mergetool works a bit different than I thought, but not by much -- the tool must be referenced by name and the corresponding mergetool.<tool>.cmd must have been set. In the command you use the variables $BASE, $LOCAL, $REMOTE and $MERGED as explained in https://git-scm.com/docs/git-mergetool#git-mergetool--tlttoolgt https://git-scm.com/docs/git-mergetool#git-mergetool--tlttoo... . This allows tools with different argument ordering, flags and such to be used. Let's write the PoC script mkdir -p ~/bin cat >~/bin/mergepoc.bash <<'EOF' #!/usr/bin/env bash echo "$0: WARN: Proof-of-Concept" 1>&2 echo "$0: INFO: Arguments: $@" 1>&2 exit 1 EOF chmod 755 ~/bin/mergepoc.bash and define the mergetool cmd git config mergetool.mergepoc.cmd '~/bin/mergepoc.bash --base "$BASE" "$LOCAL" "$REMOTE" -o "$MERGED"' and tell git to trust the exit status of this tool git config mergetool.mergepoc.trustExitCode true Then we run it. git mergetool -t mergepoc example.xml Result (with an additional line-break inserted in order for to avoid having the contents shown here scroll sideways): Merging: example.xml Normal merge conflict for 'example.xml': {local}: modified file {remote}: modified file /home/erikn/bin/mergepoc.bash: WARN: Proof-of-Concept /home/erikn/bin/mergepoc.bash: INFO: Arguments: --base ./example_BASE_4020.xml ./example_LOCAL_4020.xml ./example_REMOTE_4020.xml -o example.xml merge of example.xml failed Continue merging other unresolved paths [y/n]? n
