Compare Tom's Obvious Minimal Language and Extensible Markup Language formats — understand the key differences and when to use each

Format Overview

TOML

Tom's Obvious Minimal Language

Tom's Obvious Minimal Language (.toml) is a data file format.

.tomldata

XML

Extensible Markup Language

XML (Extensible Markup Language) is a flexible, self-describing markup language standardized by the W3C. XML uses custom tags to define data structure and is the foundation for many other formats (DOCX, SVG, XHTML, RSS, SOAP). It supports schemas (XSD), namespaces, XSLT transformations, and XPath queries. XML is widely used in enterprise systems, document formats, configuration files, and data exchange protocols. While JSON has largely replaced XML for web APIs, XML remains essential in publishing (DocBook, DITA), financial services (FIX, XBRL), and government data standards.
