[Qgis-user] select elements from a wms layer

[Richard Duivenvoorde]

Hi,
Not sure if I understand you correctly, but a WFS SHOULD be selectable 
in QGIS. Try the 'rijkswaterstaat'-url below, and you can select 1 
province, and via the attribute table copy WKT to the clipboard:

wkt_geom,MPPerimete,MPArea,AREA,PERIMETER,OMSCHR,GAQ,NL
MULTIPOLYGON(((149480.042914 476598.605781,149482.755927
... a LOT of coordinates here ...
476598.605781))),265264,143640,1436408320.0000,265278.25000,Utrecht,10,0

But if it is only the LABELS that you actually want to copy, it's 
different. Labelplacement is done using the geographic object it's 
attached to.
First I thought that you maybe could transform your original layer to a 
point-layer, but in that way you do not have the exact same label 
locations as before. But having a pointlayer with labels, they should be 
selectable, thereby copyable.

Another option?? in arcview it was/is(?) possible to transform a labels 
to a 'graphic'...
