to handle xml, use proper xml handling tools. example, task can accomplished following xsh script:

open input.xml ; perl { open $fh, '<', 'file.csv' or die $! } ; while { $line = <$fh> } {     $line = normalize-space($line) ; # remove final newline.     $ip := insert element ip append /iplist ;     set $ip/@node_id substring-before($line, ",") ;     set $ip/@netmask substring-after($line, ",") ;     insert text {"\n"} after $ip ; } save :b ;
