[R] Fwd: Parsing XML or KML into CSV /Using R for geocoding , OR problem

Hi,

I have a data file in a KML format which is Google Earth's format for
geographic data. I need to import it into a csv file . How can I do that.
KML format is just like XML format .example below

Which R module with deal with an OR problem (like transportation problem
using geo coded data as in the example below)

Regards,
Ajay

AFAIK you will need to write your own function (using the XML package) 
to extract the information you need.

For the opposite direction (i.e. generate KML from R data), Duncan
Temple Lang has material at

[R] Fwd: Parsing XML or KML into CSV /Using R for geocoding , OR problem

the
imported object to a data frame, and export to csv with write.csv().
