Frequently Asked Questions
Why does my XPath match nothing?
Namespaces (most common), wrong axis, or off-by-one predicates. Test here with highlighting — empty results name the likely cause.
XPath 1.0 or 2.0?
Browser evaluation is XPath 1.0 — no matches(), lower-case(), or FLWOR. Write 1.0-compatible paths for in-browser scraping.
Performance on large docs?
Avoid //* scans on megabyte XML — anchor to IDs and specific paths. The tool reports match counts to catch runaway queries.
Is my XML uploaded?
No — evaluation runs locally in your browser. Documents never leave your device.
