unxml demos¶

unxml turns verbose XML — schemas, stylesheets, and rule sets — into a compact, indentation-based pseudocode that is far easier to read, diff, and review than the angle-bracket original.

This site is a gallery of real-world documents rendered with unxml, so you can judge the output on files you might actually have to read: UBL and Finvoice schemas, DocBook XSL stylesheets, and EN16931 e-invoicing Schematron rules. Each page is the full output, syntax-highlighted with the same grammar unxml ships for bat.

What unxml does¶

unxml has a plain mode for any XML document, plus dedicated modes that rewrite a specific vocabulary into idiomatic pseudocode. A few examples:

Source	Rendered
`<xs:element name="Order" type="OrderType"/>`	`element Order : OrderType`
`<xsl:value-of select="$total"/>`	`<- $total`
`<assert test="cbc:EndpointID">…</assert>`	`assert cbc:EndpointID`

The result is dramatically shorter — the gallery lists original vs rendered line and byte counts for every demo (UBL's Common Aggregate Components, for instance, drops from ~40,000 lines to ~5,400).

Each mode is documented with side-by-side samples:

XSD transformations — xs:* / xsd:* schemas
XSLT transformations — xsl:* stylesheets
Schematron transformations — .sch rule schemas

Get unxml¶

unxml is an open-source command-line tool written in Rust. Point it at any XML, XSD, XSLT, or Schematron file:

# pick the mode automatically from the file extension
unxml --auto some-file.xsd

See the project README for installation (cargo, uv, or prebuilt binaries) and the full usage guide.
