Questions
Does it check against a schema (XSD)?
No. It checks that the XML is well-formed: every tag closed, properly nested and correctly escaped. Schema rules need a separate validator.
Why is “&” an error?
In XML a bare & starts a code like &. Write & for an ampersand, or put the text inside a CDATA section.
Is my data private?
Yes. Everything happens inside your own browser: nothing you type or choose is uploaded to us or anyone else.
Is it free?
Completely free, with no sign-up, no watermark and no limit on how many times you use it. Light ads keep the site running.
