I'll try:
Code:
# cat awk.file
BEGIN{
      FS="[<|>]"     # Set Field Separator
      v="SubaccId"   # Set v value, the search pattern
      }
$2==v{               # If second field equal v...
      s=$3           # Set assign third field value to s variable
      getline        # Read next line
      a[s]+=$3       # Build the a array with the s elements and sum of third field
      }
END{                 # At the end do....
    for (i in a)     # For each element of a array do..
    print v, i, a[i] # Print v (static pattern) and i (array element) and i array value.
   }

and run the code as:
Code:
awk -f awk.file data.file

evolvotron_mutate

EVOLVOTRON_MUTATE(1)						    Evolvotron						      EVOLVOTRON_MUTATE(1)

NAME

       evolvotron_mutate - Render an evolvotron function tree to an image.

SYNOPSIS

       evolvotron_mutate < function_in.xml > function_out.xml

       evolvotron_mutate -g > function_out.xml

DESCRIPTION

       evolvotron_mutate either mutates an existing image function (saved to an XML file), or (with the -g option) creates a new image function.

       The mutation parameters and function weightings are the same as used by evolvotron in its default reset state.

       See the evolvotron user manual (accessible from the evolvotron application's Help menu) for more information on image functions.

COMMANDLINE OPTIONS

       -g   Specifies that no function should be read from standard input.  The output function is created at random.

EXAMPLES

       evolvotron_mutate -g | tee function0.xml | evolvotron_render function0.ppm

       evolvtron_mutate < function0.xml > function1.xml
