I wonder how I can delete everything between the tag <client> </client> choosing the name,
eg:
I would like to delete the customer information Google:

<client>
  <dns>google.com.br</dns>
  <phone>(19)3632-9244</phone>
  <name>Google</name>
 </client>

<client>
  <dns>google.com.br</dns>
  <phone>(19)3632-9244</phone>
  <name>Google</name>
 </client>

Thanks
