view flys-client/src/main/java/de/intevation/flys/client/server/MapHelper.java @ 4740:fb135e1dfa35
Added 'type' attribute to <dc:variable/> element. If an optional 'type' attribute is given
the result of the XPATH expression is interpreted as this type.
Valid values are 'number', 'bool', 'node' and 'nodeset'. All other defaults
to 'string' which also is the default if nor type is given.
