Question sed search and replace after xml tag

Hi All,
I'm new to sed.

In following XML file
Code:
   <interface type='direct'>
      <mac address='52:54:00:86:ce:f6'/>
      <source dev='eno1' mode='bridge'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>
    <interface type='direct'>
      <mac address='52:54:00:ab:d5:77'/>
      <source dev='eno2' mode='bridge'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
    </interface>

i have add one new xml tag after <source dev='eno1' mode='bridge'/>, which is <target dev='New1'/>.

Code:
for i in `eno1 eno2 eno3 eno4`
do
        echo "Updating macvtap device names for $i"
	sed -i.bak "/source dev='$i'/a <target dev='New$cnt'/>" 
$XML_FILE
    	cnt=`expr $cnt + 1`
done

The above is not working. Please let me know how to do it?
