Frequently Asked Questions

Find Quick Answers

What is XPath and why validate it?

XPath (XML Path Language) is a query language for selecting nodes from XML documents. Validating XPath expressions ensures they are syntactically correct and return the expected nodes, which is crucial for XML processing, web scraping, and data extraction tasks.

What types of documents does this tool support?

The tool supports both XML and HTML documents. You can paste any well-formed XML or HTML content, and the tool will parse it to evaluate your XPath expression against the document structure.

Does this tool require an internet connection?

All processing happens client-side in your browser using JavaScript, so no internet connection is needed after the page loads. Your data never leaves your device.

What happens if my XPath expression has errors?

The tool will display detailed error messages explaining what went wrong, such as syntax errors, invalid axis specifiers, or function name issues. This helps you debug and fix your XPath expressions.
