XML Tag Diff

XML Tag Diff is a fast and easy-to-use application that can compare two XML documents to detect different tags and figure out what's missing. It's practical for web developers.

Select two XML files to compare tags

The interface of XML Tag Diff is clean and intuitive, represented by just one window that reveals all options put at your disposal. You can utilize the integrated file browser to indicate two XML files you're interested in comparing.

View, copy and save scan results to file

The task can be started with one click and can be stopped if it takes too long or you simply change your mind. However, there is no option implemented for pausing and resuming the scan.
Once the results are displayed, you can examine and copy them to the Clipboard by clicking a button, as well as save data to a plain text document by indicating the output directory and file name.

No setup required, besides .NET Framework

The downloaded package consists of just one executable file that can be dropped anywhere on the disk or moved to an external storage device to run it on any PC seamlessly.
Just keep in mind that .NET Framework must be installed, otherwise it won't work properly. It doesn't modify system registry settings or automatically generate files on the disk.

Evaluation and conclusion

The tool used a significant amount of system resources during XML scans in our tests. It also displayed an error dialog and crashed when attempting to scan XML with the unsupported structure on a couple of occasions.
Nevertheless, you can test XML Tag Diff for yourself if you're looking for a quick and easy solution to compare the tags of any two XML files to find out how different their content is, as well as to copy and save results to file without any hassle.
