M_AMLEngineExtensions_NavigationExtensions_FindByXPath__1

NavigationExtensions.FindByXPath(T) Method (CAEXBasicObject, String)

Searches a CAEXBasicObject from the given xPath, the type must be given in angle brackets. The search bases on XPath and is slow. For speed optimization, use FindFastByPath instead. If your CAEX file has changed, update the hash tables before using this function using updateCAEXObjectHashLists before.
