Processing markup language files can include pre-processing an original file and a new file, wherein the original file and the new file are markup language files. Pre-processing includes removing tags from the original file and the new file resulting in a pure text version of the original file and a pure text version of the new file. Using a processor, the pure text version of the original file is compared with the pure text version of the new file to determine differences. The differences are specified in a comparison result. The comparison result is post-processed by applying formatting to the differences and tags from the new file.
