xslt 1.6.15
these previous versions should be considered unusable due to the lack of proper parser implementation features. Versions 2.0 and above are a closer match to the standards.
See the version list below for details.
dotnet tool install --global xslt --version 1.6.15
dotnet new tool-manifest
dotnet tool install --local xslt --version 1.6.15
#tool dotnet:?package=xslt&version=1.6.15
nuke :add-package xslt --version 1.6.15
xslt
Command-line XSLT 3.0/4.0 processor for .NET. Transform XML documents from the terminal using the PhoenixmlDb XSLT engine.
Installation
dotnet tool install -g xslt
Usage
# Transform XML with a stylesheet
xslt stylesheet.xsl input.xml
# Write output to a file
xslt -o result.html report.xsl data.xml
# Start from a named template (no source needed)
xslt -it main generate.xsl
# Pass parameters
xslt -p year=2026 -p title="Report" style.xsl data.xml
# Read source from stdin
cat data.xml | xslt transform.xsl
# Show timing breakdown
xslt --timing style.xsl large-input.xml
# Validate a stylesheet without running
xslt --dry-run style.xsl
# Stream large files (lower memory)
xslt --stream style.xsl large-input.xml

Takes PhoenixmlDb.XQuery 1.6.15, so the `xslt` tool and anything embedding this engine pick up
two XQuery-side fixes:
- **`fn:current-output-uri()`'s sibling problem, in reverse** — adaptive `xs:double` serialization
had two implementations that disagreed. `xquery -o adaptive 'xs:double(41) + 1'` printed `42`
where the library returned `4.2e1`. W3C Serialization 3.1 §10 settles it — an `xs:double` is
serialized with `format-number(?, '0.0##########################e0')` — so the library was
right, and the CLI now delegates to it rather than carrying a second implementation.
- **Arithmetic on a date, time or duration** raised a raw `InvalidCastException` where XPTY0004 is
required. The cause was `xs:duration`, the abstract base type: F&O defines the duration
operators only on `xs:yearMonthDuration` and `xs:dayTimeDuration`, so mixing the base type in is
a type error. W3C XQTS 29,205 → 29,316 of 31,414 (93.32%), `InvalidCastException` 125 → 14.
No XSLT engine change. Conformance is unmoved at **10,031/10,630 (94.3%)**: seven of ten groups
byte-identical, and the three that moved (`attr` −1, `strm1` −3, `strm2` −4) returned to their
previous values on re-run, which is the flakiness band those groups have shown all week
(`strm1` 694–700, `strm2` 678–684). Unit suite 1483.
