I'm trying to determine the most efficient method of parsing large (1-3 meg) RRD (Round Robin Database) files after a dump to XML on Windows.

I'm using the RRDTool-OO module to retreive my data like so: 

  $rrd->dump();

[download]
The output is dumped to STDOUT in XML format.
Is it possible to parse STDOUT and store it in some data strcuture? My other concern is that this data structure will chew up a large amount of memory, so is it possibly to use pointers at all?

I'm assuming it's faster to parse STDOUT vs dumping the data to a file and then using XML-Parser to create and store my data structure.

Any ideas or suggestions would be greatly appreciated.
