Oleg, What would I need to parse:
other xml here. Start at first "<wpt lat=" ....................................... <wpt lat="42.13350000" lon="-88.97320000"> <time>2009-08-24T01:03:09Z</time> <name>99BYTH</name> <desc>40</desc> <link href="http://geodashing.gpsgames.org/cgi-bin/dp.pl?dp=GD99-BYTH";> <text>GD99-BYTH</text> <type>text/html</type> </link> <sym>Geocache</sym> <type>Geocache|Virtual Cache</type> <extensions> <label xmlns="http://www.topografix.com/GPX/gpx_overlay/0/3";> <label_text>99BYTH</label_text> <text xmlns="http://www.topografix.com/GPX/gpx_style/0/2";> <font> <family generic="sans-serif"> <face>Arial</face> </family> </font> </text> </label> </extensions> </wpt> <wpt lat="45.84690000" lon="-88.47240000"> <time>2009-08-24T01:03:09Z</time> <name>99BYYL</name> <desc>120 wood</desc> <link href="http://geodashing.gpsgames.org/cgi-bin/dp.pl?dp=GD99-BYYL";> <text>GD99-BYYL</text> <type>text/html</type> </link> <sym>Geocache</sym> <type>Geocache|Virtual Cache</type> <extensions> <label xmlns="http://www.topografix.com/GPX/gpx_overlay/0/3";> <label_text>99BYYL</label_text> <text xmlns="http://www.topografix.com/GPX/gpx_style/0/2";> <font> <family generic="sans-serif"> <face>Arial</face> </family> </font> </text> </label> </extensions> </wpt> ....................... more of the same Other xml To: +-----------+------------+------+--------+ |42.13350000|-88.97320000|99BYTH|40 | +-----------+------------+------+--------+ |45.84690000|-88.47240000|99BYYL|120 wood| +-----------+------------+------+--------+ | | | | | First 2 columns from: <wpt lat="42.13350000" lon="-88.97320000"> Next column from: <name>99BYYL</name> Last column from: <desc>120 wood</desc> I'm doing this now with a fairly complex set of verbs.

Simple things are really simple; complex are, well, possible. Just to give you an idea. Say, covert an HTML table to J table. <table> <tr> <td>0 0</td><td>0 1</td><td>0 2</td><td>0 3</td> </tr><tr> <td>1 0</td><td>1 1</td><td>1 2</td><td>1 3</td> </tr><tr> <td>2 0</td><td>2 1</td><td>2 2</td><td>2 3</td> </tr> </table> Here's all the code with definition and execution: require 'xml/sax/x2j' x2jclass 'px2j3' 'Items' x2jDefn / := table : table=: 0 0$0 tr := table=: table,row : row=: '' td := row=: row,<y ) process_px2j3_ TESTX2J3 +---+---+---+---+ |0 0|0 1|0 2|0 3| +---+---+---+---+ |1 0|1 1|1 2|1 3| +---+---+---+---+ |2 0|2 1|2 2|2 3| +---+---+---+---+ See the link above for more of exciting examples, such as nested structures and attributes handling. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
