large xml database

Hi,<br />i have very big XML documment which is larger than 50GB and want to import it into databse, and transform it
torelational schema.<br />When splitting this documment to smaller independent xml documments i get ~11.1mil XML
documents.<br/> I have spent lots of time trying to get fastest way to transform all this data but every time i give up
becauseit takes too much time. Sometimes more than month it would take if not stopped.<br />I have tried to insert each
lineas varchar into database and parse it using plperl regex..<br /> also i have tried to store every documment as XML
andparse it, but it is also to slow.<br />i have tried to store every documment as varchar but it is also slow when
usingregex to get data.<br /><br />many tries have failed because 8GB of ram and 10gb of swap were not enough. also
sometimesi get that more than 2^32 operations were performed, and functions stopped to work.<br /><br />i wanted just
toask if someone knows how to speed this up.<br /><br />thanx in advance<br /><br />-- <br
