XMLType - extract multiple nodes???

[msf11]

Hi,

I'm trying to select mulitple records from an XMLType file. Here is my code:

SELECT
report_date,
EXTRACTVALUE(tr.trx_data , '/trx-report/body/line/external-id/text()') "External ID"
FROM
TRX_REPORT tr

The error i get is:
ORA-19025: EXTRACTVALUE returns value of only one node

Is there a function that will select multipe nodes and output each node as a single record?

Thanks for the help!
