Hello,
Is it possible to use parameters in SLD instead of fixed values?
For example my filters are defined in following way:
<Filter>
<PropertyIsEqualTo>
<PropertyName>StatID</PropertyName>
<Literal>2</Literal>
</PropertyIsEqualTo>
</Filter>
...
<Filter>
<PropertyIsEqualTo>
<PropertyName>StatID</PropertyName>
<Literal>3</Literal>
</PropertyIsEqualTo>
</Filter>
I would like to use variables defined for example in some java class and to
use them
instead fixed values (2, 3, and so on) like:
<Filter>
<PropertyIsEqualTo>
<PropertyName>StatID</PropertyName>
<Literal>some predefined parameter</Literal>
</PropertyIsEqualTo>
</Filter>
...
<Filter>
<PropertyIsEqualTo>
<PropertyName>StatID</PropertyName>
<Literal>some predefined parameter</Literal>
</PropertyIsEqualTo>
</Filter>
In that way i could change their values in future only in that class and not
in whole (large) SLD.
Best regards.
