The OGR style is the variable that is returned in the variable that is casted.
Please look at the Layer definitions that I sent yesterday in the mapfile
example.
DATA "SELECT Name as NAME, CAST(OGR_STYLE AS character(32)) AS STYLE FROM
'Fibertech solution' WHERE OGR_GEOMETRY='LINESTRING'"
CLASSITEM "STYLE"
LABELITEM "NAME"
CLASS
EXPRESSION "@msn_ylw-pushpin4"
That is the STYLE value used in the CLASSITEM expression.
The description is shown in the label that uses the labelitem. Also shown in
the mapfile example yesterday.
If You only want to get the features with the style ‘@msn_ylw-pushpin4' with
ogrinfo you should write it like this:
ogrinfo -ro doc_test.kml \
-sql "SELECT *, CAST(OGR_STYLE AS character(255)) AS STYLE FROM 'Fibertech
solution' \
WHERE OGR_GEOMETRY='LINESTRING' AND OGR_STYLE='@msn_ylw-pushpin4'" –al
That returns the geometry and variables according to this criteria, i.e. only
lines and specific style.
But I guess that You most likely would like to do this filtering in the Class
section of the mapfile and not in the DATA statement.

Hi,
I am unable to get the Styleurl using Ogrinfo. I am trying the command
ogrinfo -al doc_test.kml -where "ogr_style='@msn_ylw-pushpin4'"
but the result is
Layer name: Fibertech solution
Geometry: 3D Unknown (any)
Feature Count: 0
Layer SRS WKT:
