For example you have written script considering the previous entries (/WindowXP/XpBoot.iso,hdc). It can be anything But it will have an .iso in the end that is sure.
Code:
# cat myfile
acpi = 1
 apic = 1
 builder = 'hvm'
 device_model = '/usr/lib/xen/bin/qemu-dm'
 disk =  ['file:/var/ovs/mount/825D2FF7ED2645428AD5AED714B5E777/running_pool/IFLMUD5IM0196/System-hdc.img,hda,w',
 'file:/var/ovs/mount/825D2FF7ED2645428AD5AED714B5E777/iso_pool/WindowXP/XpBoot.iso,hdc:cdrom,r',
 ]


we let take line which change line
Code:
 
previous=$( (sed -n "/\(file:.*,hdc:cdrom,r'\)/p" myfile) )

nextline is must be your new line so you input what you want this Smilie
Code:
 
next="file:/var/ovs/mount/825D2FF7ED2645428AD5AED714B5E777/iso_pool/Window2003/XpBoot.iso"

and you can use change line one time
Code:
 
sed -e "s|$previous| '$next,hdc:cdrom,r'|" myfile
 
acpi = 1
 apic = 1
 builder = 'hvm'
 device_model = '/usr/lib/xen/bin/qemu-dm'
 disk =  ['file:/var/ovs/mount/825D2FF7ED2645428AD5AED714B5E777/running_pool/IFLMUD5IM0196/System-hdc.img,hda,w',
 'file:/var/ovs/mount/825D2FF7ED2645428AD5AED714B5E777/iso_pool/Window2003/XpBoot.iso,hdc:cdrom,r'
 ]
