What Hx ML Does
HXML.com sits at the intersection of the markup family — HTML, XML, and the .hxml build files Haxe developers know — with practical guides for reading, writing, and validating each.
Elements, attributes, namespaces, and well-formedness from a blank file up.
Two cousins with different rules — where they agree, diverge, and trip people up.
The compiler-arguments format used by the Haxe toolchain, documented flag by flag.
Catching malformed markup with validators before it catches you in production.
XML to JSON, HTML to XHTML, and back — with the edge cases named.
DTD, XSD, and RELAX NG: how a schema turns markup into a contract.
How Hx ML Works
Start with well-formedness — the grammar every markup document must obey.
Run your documents through a validator and fix what it names.
Use the recipes when data must cross between XML, HTML, and JSON worlds.
About
HxML — Where the markup family meets Part of the VentureOS network of 20,000+ smart entities, each built to create real value in its vertical. Backed by 63+ specialist agents, shared infrastructure, and a unified economy.
Read it as the meeting point of the markup family — HTML and XML — plus the literal .hxml file extension used for Haxe compiler configuration.
Yes: configuration files, feeds, invoices, office documents, and countless enterprise APIs still speak XML daily.
No — the .hxml guide documents a public file format; the Haxe project itself lives at its own official site.
