XML\xpath search expression

[CarmeloMax]

<?xml version="1.0" encoding="utf-8"?> <ABC> <CDE> <FHI> <ADDRESS INTERVAL-TYPE="CLOSED">1</ADDRESS> <ACK INTERVAL-TYPE="CLOSED">1</ACK> <JKL> <ID TI="abc">Q11001</ID> </JKL> </FHI> <FHI> <ADDRESS INTERVAL-TYPE="CLOSED">2</ADDRESS> <ACK INTERVAL-TYPE="CLOSED">2</ACK> <JKL> <ID TI="def">Q11002</ID> </JKL> </FHI> <FHI> <ADDRESS INTERVAL-TYPE="CLOSED">3</ADDRESS> <ACK INTERVAL-TYPE="CLOSED">3</ACK> <JKL> <ID TI="ghi">Q11003</ID> </JKL> </FHI> </CDE> </ABC>

I am learning XPATH for processing XML file. I want to find the value of ADDRESS via value of ID. I created several, but failed.
check_xpath = '/ABC/CDE/FHI[ID=Q11002]/ADDRESS/text()'
The result is always empty.

Where am I incorrect？
