[postgis-users] WKT parsers

[Paul Ramsey]

Mark,

If you have the opportunity, avoid parsing WKT and either (a) use an 
internal postgis transform like AsSVG, AsGML, AsKML or (b) pull 
text-based binary, and parse the WKB, which is a much more predictable 
structure (using encode(asbinary(geom),'hex') ).

I guess my answer could be phrased as a question: what are you going to 
do with the WKT once you parse it? Perhaps PostGIS needs another 
representation function (I'm sure we'll have an AsJSON soon enough...)
