                                ClassAdParser

Streaming SAX handler for the output of condor_* -xml calls; it's around 60 times faster and has a similar reduction in required memory.

Use this as a ContentHandler for a SAX parser; call getJobInfo afterward to get the information about each job.

getJobInfo returns a dictionary of jobs; the key for the dictionary is the Condor attribute passed in as 'idx' to the constructor; the value is another dictionary of key-value pairs from the condor JDL, where the keys is in the attribute list passed to the constructor.
