[Mapserver-users] OGC-compliant WMS-server deliveringdynamic layers with MS?

Hi Debbie,
Hi Tom,

Agreed, in my understanding of getFeatureInfo it must be a pure "dump"
in one of the following formats
"Text/plain", "Text/html" or "Gml features".

I will keep you informed of my progress and will share the parts which
are "reusable". ;-) But I think in the first extension I will limit to
the text/plain-option.

Yes it's optional, and I'm quibbling! ;-) But if I want to use a php as
a wms-server and another server uses the first one with wms-requests
(thinking of a cascading architecture) I don't think it could handle
this url. And if the html-output is formatted this way, I can't reformat
it without parsing.

Another thought: Does anybody know what my PHP must return to MS so it
could handle the output in a template-file using the text/html-option?
And is there a way to use the result-set in a template-file without
knowing the name of every feature. I'm thinking of something like:
<html>
[1]<br>[2]
</html>

instead of :
<html>
[NAME]<br>[CODE]
</hmtl>

The problem is the features returned by my dynamic-layers will have a
dynamic structure too! Or does this directly lead to using the
gml-feature-format.

Thinking about the GML-info_format: Is there any feature in MapScript or
PHP helping to get this document assembled or do I have to code this
from the scratch?

TIA,
Frieso
