What version of MapServer?
Also, what is the part in the map file that is causing the problem:
* if you remove the EXPRESSION ("[amenity]" = "post_box") from the
generated map, will that work
* Is the layer's FILTER element set (on the generated map)? If so what
is the value?
A full layer definition in the generated map would be useful. A full sld
might also help.

Hello,
We're using a OpenStreetMap Postgis database as a source for our
geo-servers. We want to provide WMS and WFS services on the data. In
order to do the styling only once, we are using SLDs, which works
mostly fine.
One of our layers does not render as a WMS, it throws a
"msEvalRegex(): Regular expression error. String failed expression
test." Error during execution.
We identified the layer, and it's the one rendering post boxes. The
corresponding SLD definition is using a filter:
<Filter>
<PropertyIsEqualTo>
<PropertyName>amenity</PropertyName>
<Literal>post_office</Literal>
</PropertyIsEqualTo>
</Filter>
Using debug-level 5, the mapfile after SLD application looks like
# ...
# more definitions
# ...
CLASSITEM "amenity"
DATA "nway FROM
(SELECT way as nway, osm_id, amenity, name
FROM planet_osm_point
WHERE amenity='post_box'
OR amenity='post_office'
)
as foo using unique osm_id using SRID=900913"
# ...
# more definitions
# ...
CLASS
NAME "Unknown"
EXPRESSION ("[amenity]" = "post_box")

ANGLE 360
COLOR 0 0 0
SIZE 40
SYMBOL "http://192.168.0.111:8502/sld/img/briefkasten.png";
WIDTH 1
END
END
We simply can't figure out, what might be the problem here. The whole
issue seem to be related to the filter element, removing it makes the
layer render. Using the generated map layer, rendering fails with the
same error.
So I would be happy if someone with more experience with SLDs can give
me a hint about whats going wrong here.
