Remove element of xml

[stampede]

Quick and dirty solution could be to use regular expressions.
Yours could look like this (pseudocode):

<client>/*whatever*/<name>/*maybe whitespaces*/ClientToDelete/*maybe whitespaces*/</name>/*whatever*/</client>

<client>/*whatever*/<name>/*maybe whitespaces*/ClientToDelete/*maybe whitespaces*/</name>/*whatever*/</client>

To copy to clipboard, switch view to plain text mode 

Don't forget to set it for minimal match, it'll eat up all your xml otherwise (if it founds ClientToDelete).
