Split the 658-line modules_controller.py into focused, single-responsibility files: - ComboboxStateHandler -> controllers/combobox_state_handler.py (177 lines) - SearchXMLOutputTextHandler -> controllers/xml_output_search_handler.py (48 lines) - XPath handlers -> controllers/xpath_handlers.py (245 lines) - CSV service handlers -> services/csv_service_handlers.py (172 lines) - XML service handler -> services/xml_service_handlers.py (39 lines) modules_controller.py now acts as a facade (31 lines) that re-exports all classes for backward compatibility.

The 658-line
modules_controller.pyviolated Single Responsibility Principle by containing 10 unrelated handler classes, making navigation and maintenance difficult.Changes
Extracted handlers into focused modules organized by concern:
UI State Controllers (

controllers/)xpath_handlers.py(245 lines) - Three related handlers:AddXPathExpressionToListHandler- Expression validation and list managementXPathBuildHandler- Expression building from UI selectionsGenerateCSVHeaderHandler- Header generation from expressionsService Orchestrators (
services/)csv_service_handlers.py(172 lines) - Four CSV orchestrators:CSVConversionHandler,SearchAndExportToCSVHandlerLobsterProfileExportCleanupHandler,CSVColumnDropHandlerxml_service_handlers.py(39 lines) -ParseXMLFileHandlerBackward Compatibility
modules_controller.pyreduced to 31-line facade re-exporting all classesArchitecture
Clear three-layer separation now enforced:
