KDiff3 is not XML specific, but it is free. It does a nice job of comparing and merging text files.

I use TortoiseMerge, which is included in TortoiseSVN program

And we have talked about File Diff tools in this thread, not dedicated to XML though

While this is not a GUI tool, my quick tests indicated that diffxml has some promise. The author appears to have thought about the complexities of representing diffs for nested elements in a standardized way (his DUL - Delta Update Language specification).

Installing and running his tools, I can say that the raw text output is quite clear and concise. It doesn't offer the same degree of immediate apprehension as a GUI tool, but given that the output is standardized as DUL, perhaps you would be able to take that and build a tool to generate a visual representation. I'd certainly love to see one.

The author's "links" section does reference a few other XML differencing tools, but as you mentioned in your post, they're all proprietary.

Altova's DiffDog has free 30-day trial and should do what you're looking for:

This is a diff engine for java developers, but it comes with a demo interface - you might be able to use it: https://community.emc.com/docs/DOC-5042

I recommend you to use CodeCompare tool. It supports native highlighting of XML-data and it can be a good solution for your task.

I wrote and released a Windows application that specifically solves the problem of comparing and merging XML files.

Project: Merge can perform two and three way comparisons and merges of any XML file (where two of the files are considered to be independent revisions of a common base file). You can instruct it to identify elements within the input files by attribute values, or the content of child elements, among other things.

It is fully controllable via the command line and can also generate text reports containing the differences between the files.

Pretty Diff tool was created with XML in mind. Just ensure you click the option for "markup".

Have a look at File comparison tools, from which I am using WinMerge. It has an ability to compare XML documents (you may wish to enable DisplayXMLFiles prefilter for v2.14.0 or PrettifyXML for v2.16.x).

DisplayXMLFiles.dll - This plugin pretty-prints XML files nicely by inserting tabs and line breaks. This is useful for XML files that do not have line returns in convenient locations.

Note for v2.16.x

The plugin PrettifyXML is supplied with the software package. It can be activated as following:

Make sure that Plugins → Plugin Settings → Enable plugins is enabled.
Then use either File → Recompare As → Prettify XML or Plugins → Scripts → Prettify XML

For those who wish to play with deprecated DisplayXMLFiles, he needs to download e.g. winmerge-2.16.14-full-src.7z and copy Plugins\dlls\X64\DisplayXMLFiles.dll to WinMerge\MergePlugins\.
