Comparing XML files
XML documents — config files, SOAP payloads, Android layouts, RSS/Atom feeds — are often edited by hand or generated by different tools, which makes small unintended changes easy to miss. This tool does a straightforward line-by-line comparison, which works well for spotting added or removed tags, attribute changes, and reordered elements.
For best results, keep the indentation style consistent between the two versions you're comparing — differences in whitespace alone will show up as line changes.
Frequently asked questions
- Does this validate my XML?
- No, this is a text comparison tool, not a validator. It will happily diff invalid XML too.
- Will it ignore whitespace-only differences?
- Not automatically. If whitespace or indentation differs between the two documents, those lines will be flagged as changed.
- Can I use this for HTML too?
- Yes, the same line-by-line comparison works for HTML, SVG, or any other markup.
