[mapserver-users] WMS getcapabilities error: invalid character

[Paul Ramsey]

Mapserver will merrily spit whatever you put in your wms_* metadata
lines into the XML capabilities, even if the contents of the metadata is
not valid XML. The solution is to use XML entities where necessary:

Replace all occurences of & with &
Replace all occurences of < with &lt;
Replace all occurences of > with &gt;

That will fix the XML problems. As Daniel also notes, if your data is a
URL, you should be careful to URL-encode the data you put in that URL,
but that is good advice for any web programming, not just mapserver :)
