title: qgis (segment (link) start node and end node id's extraction from shapefile )
body: <p>I have been dealing with a lot of shape files editing tools last month..
  I tried to get two dbf files from shape file (one for nodes and one for links) in an appropriate format (node_id,x,y for nodes and link_id,start_node_id,end_node_id,...for links)in order to create  an oracle spatial network.
  I got the dbf for nodes..
  I want now to get the attribute table from a loaded shape file containing polylines (roads) and I want to split each polyline to its segments containing their start and end node id's besides their geometry..
  Every help accepted..</p>
