[OpenLayers-Users] loading XML problem

[Bart van den Eijnden (OSGIS)]

Hmm, it gets trickier.

I was using the code from Omniverdi's WMSManager.

But since the mimetype of a OGC WMS 1.1.X GetCapabilities response  is
application/vnd.ogc.wms_xml, I cannot use responseXML in IE :-(

This leads me to the following conclusion: when using ISO-8859-1 and having
special characters in an OGC WMS 1.1.X GetCapabilities document you cannot
parse the XML from an AJAX request client-side with IE .... or am I missing
something?

Best regards,
Bart
