Solution

In Python it is easy:

to_add = """<vhostMap>
  <vhost>google</vhost>
  <domain>google.com, www.google.com</domain>
</vhostMap>
"""
with open("config.xml", "r") as f:
    all_lines = f.readlines()
with open("config.xml", "w") as f:
    for l in all_lines[:8]: f.write(l)
    f.write(to_add)
    for l in all_lines[8:]: f.write(l)
