Read data from a DXF file into a DXF XLINE entity.
The last line read from file contained the string "XLINE".
Now follows some data for the XLINE, to be terminated with a " 0" string announcing the following entity, or the end of the ENTITY section marker ENDSEC.
While parsing the DXF file store data in xline.
