Hi Don,
Thanks a lot for the informative response.
My apologies for the misleading messages.
The Customized Tags, are the Tags substituted as gml:AbstractFeature.
During conversion, I planned to generate also the tags itself aside from
the values (attribute values).
Then, dbf column names are limited to 10 chars (if I'm not mistaken).
That's why I am having problem on
how to extract the tag names.
Last Friday (2011/1/21), I decided to have a gml template file. Then,
just replace only the values by having a another
mapping file to determine the element name(tag) by dbf field name.
Thanks a lot.
With appreciation,
Eros
