Invisible XML is a language for describing the implicit structure of data, and a set of technologies for making that structure explicit as XML markup. It allows you to write a declarative description of the format of some text and then leverage that format to represent the text as structured information.
Invisible XML (ixml) 1.0 was published on 10 June, 2022. The grammar of Invisible XML is defined with Invisible XML. The ixml grammar for ixml is available in ixml format or in xml format . Invisible XML was developed by the Invisible Markup Community Group (CG) at the W3C .
The current working draft is also available. This draft includes the resolved errata and any additional proposals adopted since the 1.0 specification was published.
