PhoenixmlDb.Xslt

XSLT 4.0 transformation engine for PhoenixmlDb — transform XML documents into HTML, JSON, CSV, text, or other XML formats.

Features

  • XSLT 3.0/4.0 — template matching, streaming, accumulators, packages, maps/arrays
  • All output methods — HTML5, XML, XHTML, JSON, text, CSV, adaptive
  • Multiple outputs — xsl:result-document for multi-file generation
  • Full XPath 4.0 — 240+ built-in functions available in all expressions
  • Packages — reusable stylesheet libraries with visibility control

Quick example

using PhoenixmlDb.Xslt;

var transformer = new XsltTransformer();
await transformer.LoadStylesheetAsync(
    File.ReadAllText("style.xsl"),
    new Uri(Path.GetFullPath("style.xsl")));

transformer.SetParameter("title", "My Report");
var html = await transformer.TransformAsync(
    File.ReadAllText("data.xml"));

// Handle secondary outputs (xsl:result-document)
foreach (var (href, content) in transformer.SecondaryResultDocuments)
    File.WriteAllText(Path.Combine(outputDir, href), content);

See the full API overview in the README.

Takes **PhoenixmlDb.XQuery 2.2.0** and **PhoenixmlDb.Core 2.0.0**.

XQuery moves with this release and the order matters: that package carries `xs:IDREFS`,
`xs:NMTOKENS` and `xs:ENTITIES` as cast targets (+63 QT3 cases). Had this shipped against the
2.1.0 pin, none of those would have reached anyone installing `PhoenixmlDb.Xslt`.

### Fixed

- **`xsl:expose` selected nothing, silently.** Component names, the value space and the missing
 token forms (#162). **+13 W3C cases.**
- **Three error sites named a neighbouring code** (#155). **+12 W3C cases.**
- **A streamed `group-adjacent` key that returns elements is now rejected** as `XTSE3430`, and a
 streamed `group-adjacent` with an empty key reports `XTTE1100` like its buffered twin rather
 than a misleading `XTDE1071` (#168, #152). Both halves of Martin Honnen's #147.
- **`xsl:sort` and `xsl:key` did not set temporary output state**, so `xsl:result-document`
 inside a sort key ran instead of raising `XTDE1480` (#158).
- **The runner never set a base output URI**, so every `current-output-uri()` case saw `()` (#159).
- **`regex-group()` returned the empty sequence inside a pattern** (#154).
- **A text node returned by `xsl:function` was not a real node** — axis steps raised `XPTY0020`
 naming an internal type (#151).
- **Static declarations now come into scope in declaration order** (#167).
- **The streaming scanner descends into `xsl:map` and `xsl:map-entry`** (#128).
- **`xsl:use-package` whitespace declarations have a relative import precedence** (#145).

### Performance

**A match pattern carrying any predicate was O(n²) in sibling count** (#169). The predicate's
content was irrelevant — `w:p[@zzz]` cost the same as one walking every descendant twice, because
the cost was establishing `position()`/`last()` context for a predicate that cannot observe it.
Measured on the issue's own repro: **12.6× faster at n=4000**, and a predicate now costs 3% over
having none rather than 250%.

### Conformance

**W3C XSLT 3.0: 10,384 / 10,839 (95.80%)**, up 37 passes from 2.1.0's 10,347.

The denominator is unchanged, so this is the engine doing more rather than cases leaving the
count. Measured on this commit against the **published** `PhoenixmlDb.XQuery 2.2.0` package — not
sibling source — so it describes the artifact being released.

### Known limitations

- A streamed `xsl:message` loses items produced by `xsl:for-each` in its content (#148). The
 obvious fix makes it worse: the message loses its constants too.
- Three streaming sets remain below their 1.6.10 scores (#96). Not a regression — those cases
 passed by not streaming at all until `streamable="true"` began actually streaming.

> **Correction (2026-09-04).** Every W3C XSLT conformance figure recorded in this file before
> this date is overstated. Tests expecting a specific error code were scored as passes whenever
> the transform threw anything at all, because both conformance runners read the expected code
> from element text when the corpus writes it as an attribute. Re-measured against the same
> corpus, the figure **on that date** was **10,020/10,630 (94.3%)**. The historical entries below
> are left as written — they record what was believed at the time. See BUGS.md entry 28.
>
> That 94.3% is itself now historical; do not quote it as current. The live figure is in
> `README.md` and in the generated `STATUS.md`, each carrying its own measurement date.
