2014-04-26	Implemented global DOM document cache	Adrian Kummerländer
	* the plan to return XML-nodes from each external function requires a better way to manage the lifetime of many xerces DOM document instances and their support class instances this is why DomDocumentCache and DomDocumentCache::item were implemented based on std::map so we can easily access the result of old function calls * changed external read-directory function to return the children of the document node instead of the document node itself removes unnecessary cruft in function calls will make returning status codes alongside the function result more pleasing to the eye * updated test transformation to reflect new features
2014-04-23	Fixed xerces DOM construction related memory leaks	Adrian Kummerländer
	* Wrapped xerces DOM and support class instances in now DomDocumentGuard scope-guard class * FunctionReadDirectory class contains interal std::stack instance to store DomDocumentGuard instances wrapped in std::shared_ptr as FunctionReadDirectory is internally cloned by xalan... this is needed as the DOM has to preserved longer than the external function execution scope * Sadly XMLCh xerces strings have to be manually released ** added appropriate xercesc::XMLString::release calls * xalan::XercesDOMWrapperParsedSource does not mirror a given xerces DOM but convert it on instantiation ** this is why there is a dedicated finalize member method in InputXSLT::DomDocumentGuard * In short: I do not like the amount of trickery needed to simply prevent memory leaks in this context ** there sadly doesn't seem to be a substantially easier way to return arbitrary DOM trees from a external function
