Thanks!

Subject: Re: [scripting] exporting keys
Here's the code that I used to use to write fcurves to XML. This is part of a larger framework, so don't worry if you feel like there's code missing.
Should get you started. You don't need any command, the object model provides everything you need for that.
def writeFcurve( self, oParameter, iSpace ):
"""
Write the override entry type as a parameter.
"""
self.aFileLines.append(
' '.join( [
'%s<parameter' % ( ' ' * iSpace, ),
'scriptname="%s"' % ( oParameter.scriptname, ),
'valuetype="%i"' % ( oParameter.valuetype, ),
'sourceclassname="FCurve"',
'inputid="0"',
'entrytype="2">\n'
] )
)
# Get the fcurve
oFcurve = oParameter.source
# Check if fcurve has keyframes
if oFcurve.keys.count > 0:
iSpace2 = iSpace + 2
self.aFileLines.append( '%s%s<fcurve plotted="%s">' % ( '\n', ' ' * iSpace2, str(bPlotted) ) )
