Update WmtsParser.cs: adding a test if a layer has no Style

[franky235]

The idea is to avoid NullReferenceException that cancel parsing Continue parsing instead

Thanks. In what kind of service did you run into this null value? It still valid according to the spec? Even if not valid it is good to check for it, just curious.

Good question, I am curious too
I checked and the layer ADMIN_EXPRESS is not valid according to wmts1.0 xsd schema ! (Style is missing...)
I will contact IGN to ask them to fix it but it is a large public company, not very responsive
In the mean time I need to move forward

BTW, thanks for your quick reply !

FYI QGIS can parse IGN WMTS getcapabilities even if not fully compliant to the spec
I think it would be good if BruTile can do it also, after all it is a minor change don't you think ?

BruTile should function properly even if the service does not comply to the specification. Good fix.
