Hi
as mark poits out this is a case where tcl will do the job in just a few
lines off code
somthing like this, I am home now so I can not check that the syntax i
correct, but I think it should work, I use this approach a lot, in some
cases I put the mapping of the attributes in an external file, this way we
just have to change this file - and not the mapping file - when the data
changes
just use the TCLExecuter transformer? to run the function
proc dynamicRename {} { \
foreach attr [ lsearch -regexp -inline -all [FME_AttirbuteNames]
"data_feat_" ] { \
FME_RenameAttribute [lindex [split $attr _] end] $attr ; \
} ; \
}
I just love this command
set attrLst [ lsearch -regexp -inline -all [FME_AttirbuteNames]
"data_feat_" ]
basede on a regular expression it will give you all attributes on a feature
matching the expresion
when we have the list we can run trough the it with a foreach command
renaming the attributes using split and lindex to extract the last part off
the name
