[Maria-discuss] Connect engine assistance needed with nested first node in XML
by Rasmus Johansson 04 Feb '14

04 Feb '14

Hi, I'm trying to parse GPX files, which are XML with the connect engine. They look like this: <?xml version="1.0" encoding="UTF-8"?> <gpx version="1.1" creator="runtastic - makes sports funtastic, http://www.runtastic.com"> <trk> <trkseg> <trkpt lon="-0.7057708501815800" lat="51.4470825195312003"> <ele>76.6089172363281</ele> <time>2013-08-12T18:17:25.000Z</time> </trkpt> <trkpt lon="-0.7059442996978760" lat="51.4470443725586009"> <ele>72.1513061523437</ele> <time>2013-08-12T18:17:28.000Z</time> </trkpt> <trkpt lon="-0.7059520483016970" lat="51.4470558166503977"> <ele>75.0039749145508</ele> <time>2013-08-12T18:17:30.000Z</time> </trkpt> </trkseg> </trk> </gpx> Once I have the Connect -engine enabled I do the following: create table GPXSource ( lat char(20) field_format='@', lon char(20) field_format='@') engine=CONNECT table_type=XML file_name='/home/rasmus/nodegpxmariadb/public/uploads/runtastic_20130812_2157_Running.gpx' tabname='gpx/trk/trkseg' option_list='rownode=trkpt'; It doesn't work, I cannot figure out how to tell the Connect engine that the data I'm interested is beneath the gpx/trk/trkseg -node (tabname). If I remove the trk and trkseg -nodes from the data and just have the gpx -node left and all trkpt -nodes inside it everything works perfectly. Any help is appriciated.
