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

Features

  • XSLT 3.0/4.0 — packages, streaming, maps/arrays, higher-order functions, JSON output
  • Multiple output methods — XML, HTML, XHTML, text, JSON, adaptive
  • Streaming — process large files without loading into memory
  • xsl:result-document — generate multiple output files in one transform
  • Parameters — pass values from the command line
  • Timing — built-in performance profiling
  • Tracing — log template matching, function calls, and built-in rules

Streaming allocation overhaul. The 1M-item streaming-identity bench dropped from 3328.6 MiB to 368.4 MiB allocated (-88.9%) and from 4921 ms to 3412 ms (-30.7%); peak RSS stays at 16 MiB. Profile-driven series of pool / cache / laziness wins.
     Highlights: cache the seven CreateMatchContext delegates and pool the XsltContext itself via a `using var lease = AcquireMatchContext()` pattern (17 call sites migrated); pool XdmElement, XdmAttribute, StreamingNodeContext, Scope, and the per-element NodeId / XdmAttribute / StreamingNodeContext lists; lazy-init Scope.Variables / TunnelParameters and per-element attrs / nsDecls; replace the XdmInMemoryStore.GetAttributes yield-iterator with an allocation-free struct enumerator on hot paths.
     Pool reuse is safe under XSLT 3.0 streaming mode — streamable templates may not retain non-grounded node refs across element boundaries. Non-streaming paths are unchanged.
     463/463 XSLT tests green; no behavior changes. See RELEASES.md for full notes.
