jva70 opened a new pull request, #20313:
URL: https://github.com/apache/camel/pull/20313
# Description
This pull request adds support for exchange variables in XPath expressions.
Previously, XPath could only resolve values from headers and properties. With
this change, variables can now be referenced in XPath expressions using the
standard `$variableName` syntax.
The implementation adds variable resolution to the `MessageVariableResolver`
class, checking `exchange.variables` after properties in the resolution order.
This maintains backward compatibility in terms of variable resolution order
while extending XPath functionality.
Changes include:
- Modified `MessageVariableResolver.java` to resolve exchange variables
- Added `XPathVariableTest.java` demonstrating variable usage in XPath
- Updated `xpath-language.adoc` documentation with variable support
details and example
