diffxml et patchxml

Standard UNIX tools exist for comparing (diff) and patching (patch) files, which operate on a line by line basis using well-studied methods for computing the longest common subsequence (LCS). Using these tools on hierarchically structured data leads to sub-optimal results, as they are incapable of recognizing the tree-based structure of these files. This webpage hosts GNU GPL licensed XML diff and patch utilities which operate on the hierarchical structure of XML documents.
