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 outputsxsl: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);

### Fixes

- **A nested `xsl:copy` inside a typed (`as=`) template no longer vanishes from the output, taking a spurious `XTTE0505` with it.** A typed template installs a sequence accumulator, which routes `xsl:copy` of an element down its serialize-then-reparse path: the copy is written to the output buffer, sliced back out, and reparsed into an XDM node inside a synthetic wrapper element. That serialized fragment carries only the namespace declarations it needed *at its position* — any an ancestor already declares are suppressed as redundant — so a **nested** copy reparsed on its own had an undeclared prefix and threw, and the handler had already truncated the buffer: the element was destroyed outright. Validating the declared cardinality against the resulting empty capture then reported `XTTE0505: … expected exactly one item, got 0`. The synthetic wrapper now declares the in-scope namespaces so the fragment stands alone, and the parse-failure fallback restores the markup it truncated instead of dropping it. The failure required all three of a declared `as=` type, nesting, and an `xsl:copy` parent — a literal result element parent uses a different construction path and was unaffected. Reported by Martin Honnen against XSpec 4.0.3 `src/compiler/base/resolve-import/gather/gather-specs.xsl`, which this unblocks: the resolve-import stage sits on the critical path for running XSpec suites at all.
