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

Requires PhoenixmlDb.XQuery 2.8.0 and PhoenixmlDb.Core 2.4.0. W3C XSLT 3.0: 131 failing.
### Security
Security fixes for hosts that compile or run stylesheets from untrusted parties. The advisory will
be linked here when it is published.
### Schemas
- **Constructor functions of imported schema types** can be called (`t:size('8')`, `t:size#1`),
and `function-available` answers for them.
- **Schema types by prefix in XPath**: `cast as t:size` and `castable as t:size` work (#316).
- **An inline `xs:schema` in `xsl:import-schema`** is read, through the schema provider's
interface; a relative `schemaLocation` in it is relative to the stylesheet.
- **`xsl:validation` on a literal result element** is applied (#316).
- From PhoenixmlDb.XQuery 2.8.0: schemas are read through the shared schema layer and cached across
transformations, an atomic value keeps its schema type, and a schema that requires XSD 1.1 says so.
### Streaming
- **`StrictStreamability`** (opt-in; `XsltTransformer.StrictStreamability`,
`XsltTransformOptions.StrictStreamability`, CLI `--strict-streaming`) reports `XTSE3430` for a
template in a streamable mode that is not streamable (#295).
- **Two wrong results in streamed rules are fixed**: an element rule with two
`xsl:apply-templates` gave truncated output, and a document-node rule lost its second result.
### Conformance
The harness now accepts an expected error code only when the engine raised it, not when the code
merely appears in the message text (#318). With that stricter rule, W3C XSLT 3.0 is 131 failing.
