Function asks LandXML file name and reads its contents to a list. At the beginning of each line, part type is displayed: XY for vector parts, MM for terrain models and TG for road alignments. Vector part can be either model source data or pipe network. Terrain models can appear in the list twice, as a vector file and as a terrain model.
List items can be selected for reading. If no items are selected, all parts are read. Each part is read using type specific converter. Converter name is asked once for each read type (vector, model, alignment). Each part forms separate file to the element list. File is named using same rules as in LandXML file extracting.
