[mapserver-users] cascading wms and layer names encoding

[Rahkonen Jukka]

Hi,

I believe that your human readable names with space characters are invalid in XML and WMS and thus there is no much need to think about how Mapserver encodes them. If you administrate the remote service use human readable Title for the layers and use underscores or any other acceptable characters in Names. If you do not administrate the server, send email.

Unfortunately I could not find good documents as confirmation. I can only say that I am remembering that WMS layer names are defined somewhere to be of XML type Qname and perhaps somewhere here reads that white spaces are not allowed in QNames
http://www.xml.com/lpt/a/795 or here http://www.w3.org/TR/REC-xml/#NT-NameChar

I may be wrong and spaces in layer names may be theoretically OK. However, I would say that if you use them both you and your users will have trouble.

Aihe: [mapserver-users] cascading wms and layer names encoding

Hi everybody (this always reminds me of Barney from the simpsons...)

Anyway, I'm battling with cascading a wms layer that has human readable
names... like with spaces and other characters that MapServer urlencodes...

So when I have in my mapfile:

LAYER

(...)

METADATA
  wms_name  "layer with understandable name, another layer"

(...)

And I make a request to MapServer, what it sends to the original WMS server
looks like:

http://..../WMSServer/request=getmap&*layers=layer%20with%20understandable%20name%2C%20another%20layer*&other
params

As you can see the layers are encoded and unfortunately my wms server says:
/"Parameter 'layers' contains unacceptable layer names."/

Finally my question: can I tell MapServer to NOT encode the layers names???

Thanks.
Duarte
