XPath Extractor

Evaluates XPath expressions against XML/HTML payloads to extract values in test automation and debugging workflows. It supports single or multiple extractions, and can map results to variables in JMeter or other script environments.
Conceptually, you supply a payload string, an XPath expression, optional namespace mappings, and extraction controls. The engine parses the payload, resolves namespaces, evaluates the XPath, and returns node string values in document order. If extract_all is false, the first match is returned.
Who benefits: performance testers, QA engineers, and developers writing API tests, SOAP services, or XML-based messaging. Unique value includes built-in namespace handling, configurable defaults, and precise control over results without requiring XSLT or external tooling.
Core features include input validation, error handling, multi-result output, index-based selection, and seamless integration with scripting environments via plain strings. Typical use cases include token extraction, session identifiers, and dynamic parameterization of requests in JMeter tests.
