Hello,
Thanks for your response. Just to clarify I've just added the comments bellow:
>From a quick test I did locally using latest MapServer, I don;t see any particular issues with your sld. I was able to generate the labels as expected.
I'm also able to generate the labels, but the problem is that some of them are cut and thay are also repeated over the polygon. See attached file.
>Note that the anchor position is only used when labeling point features.
I thought it could be possible to add a label in the centroid of the polygon, and just one label.
>Are each polygon formed with one shape or could one polygon be formed by several adjacent shapes?
I don't understand what you mean here. I'm using Oracle Spatial as DataSource and my layer is a polygon table.
>You can also check the log files and see what your layer looks like after the sld is applied: add something like this in your map file for example:
> CONFIG "MS_ERRORFILE" "f:/logs/my_log_file.log"
> DEBUG 5
Here is what I get from the log file
[Mon Nov 23 08:54:37 2009].387000 msApplySLD(): Map file after SLD was applied C:/ms4w/Apache/htdocs/MFD/tmp/4b0a3fbd_1058_1._sld.map[Mon Nov 23 08:54:37 2009].512000 msDrawMap(): Layer 5 (municipios), 0.093s

An then I go to the file referenced in the log and I see a mapfile with the following lines, but I don't know what exaclty do I have to find...

David,
From a quick test I did locally using latest MapServer, I don;t see any particular issues with your sld. I was able to generate the labels as expected. Note that the anchor position is only used when labeling point features.
Are each polygon formed with one shape or could one polygon be formed by several adjacent shapes? You can also check the log files and see what your layer looks like after the sld is applied: add something like this in your map file for example:
CONFIG "MS_ERRORFILE" "f:/logs/my_log_file.log"
DEBUG 5
regards,
