Hi, after a lineonarea overlay I have line elements with its original 
attribute (e.g. heightlevel) and a list of attributes, originating for 
area elements (including heightlevel_1 and heightlevel_2 attribute).

I want to search the list based on the line heightlevel value; so not a 
fixed value (only one area heightlevel_1 value will match). If I find 
my match, the line heightlevel value is set to area heightlevel_2 
value. Stated differently:

IF line_heightlevel = area_heightlevel_1
THEN line_heightlevel = area_heightlevel_2
END IF

In a listsearcher, I can obly use a fixed value, rather than the value 
of a attribute.

Anyone the answer?
