About XML files
XML stores structured data as nested elements with attributes. Feeds, office documents, configuration and data exchange formats are built on it.
Open Online shows XML as a tree and as highlighted source and reports where a document isn’t well-formed.
What you can do here
- Collapsible element tree with attributes
- Source view with syntax highlighting
- Check that the XML is well-formed
- Re-indent (format)
- Edit and save
Limitations
- Validation checks well-formedness. Schemas (XSD, DTD) are not evaluated.
Privacy
The file is read by your browser and stays on your device. Open Online has no server that could receive it, and nothing is stored once you close the tab. Privacy policy
Common questions
Does it validate against a schema?
No, it checks well-formedness only: matching tags, quoting and escaping.
Can it format minified XML?
Yes. Format re-indents the document.
