[Mapserver-users] Mapscript doesn't write map file in expected order!

[Xiaoyuan Geng]

The map file updated from the PHP mapscript is expected to be readable
with WMS clients or viewers such as Intergraph's WMSVIEWER. The segment
of the METADATA produced from the script is not well ordered and the map
file is not valid for the WMS viewers. After I rearrange the order and
get ride of the tabs manually, everything works fine. That is why this
issue matters in my case. Also the PHP mapscripts add more unwanted
segments such as "scalebar" and "querymap". However I might overlooked
some other bugs from side.

Thanks!

Shawn,

Why should this matter?  My understanding is that there is no
significants
to the metadata item order. Also, whats wrong with emitting a tab as
the
spacer?  It still reads and parses as a map file properly, right?
