XSLT tester
Run an XSLT 1.0 transform in your browser — and when the output comes back empty with no error, find out which namespace mismatch stopped every template from firing.
Run by your browser's own XSLT 1.0 engine. The reason this tool exists is the failure it diagnoses: when the source document has a default namespace and the stylesheet's match patterns have no prefix, no template ever fires — the transform succeeds, the output is empty, and nothing is reported as wrong. Try the silent-failure stylesheet above to see it. Nothing you paste is uploaded.
