[gdal-dev] Access to MetaData in driver implementation

[lidiriel]

Hello,

I work on th create method for ISIS2 file (PDS driver). I can write
raster file but i have a problem with meta data.
In the case where the user would be use "poDriver->CreateCopy" i try
to copy and write metaData in the new file. But now i get metadata
with the method "char** metaData = GetMetadata();"
But the list of string is not easy to handling.
Is there another solution for access to the metadata for creating a new
(or updated copy) of header ?
Construct and access to an XML tree (like TrySaveXML) ? or another
method ?

Regards
