- Around line 153-156: Update the path handling in the visitors for
PathSelectCondition and PathSelectExpr to extend the current path with the
nested scope name instead of replacing it. Preserve the existing behavior when
no enclosing path is set, and continue restoring the previous path after
visiting each child.

Preserve the enclosing path for nested scopes.
XML parsing can create nested PathSelectCondition and PathSelectExpr nodes. When an outer scope visits an inner scope, these assignments discard the outer path. The rendered reference then uses only the inner name instead of the full nested path.
Suggested fix
- _path = condition->name();
+ _path = old.empty() ? condition->name() : old + "." + condition->name();Apply the same path extension in _accept(const PathSelectExpr*).

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
