    GNU sed:

    sed '10a <vhostMap>n  <vhost>google</vhost>n  <domain>google.com,www.google.com</domain>n</vhostMap>' config.xml

    Almost the same with awk:

    awk '{ print $0 ; if(NR == 10) printf "<vhostMap>n  <vhost>google</vhost>n  <domain>google.com, www.google.com</domain>n</vhostMap>n" }' config.xml

    This might work for you (GNU sed and shell):

    cat <<! | sed '10r /dev/stdin' file
<vhostMap>
  <vhost>google</vhost>
  <domain>google.com, www.google.com</domain>
</vhostMap>
!

    Place the lines to be appended in a here-doc and append them after line 10 of the file by reading them in as stdin via a pipe.
