[GraphHopper] Fwd: feed Graphhopper with String

[Peter K]

Hmmh, indeed it would be better if OSMReader accepts a Reader ... but
this is not easy as we need to read from it twice. So, yes your solution
with cloning the OSMReader functionality would be one way or create a
temporary file from the xmlContent which you then can normally read in.

Regards,
Peter.
