awk - sed / reading from a data file and doing algebraic operations

Hi everyone,
I am trying to write a bash script which reads a data file and does some algebraic operations.
here is the structure of data.xml file that I have;

Code:
1 <data>
2 .
3 .
4 .
5 </data>
6 <data>
7 .
8 .
9 .
10</data>
etc.

Each data block contains same number of lines (say for example 5 lines)

Q1. How can I find the total number of data blocks in a given data file?

Q2. How can I assign that number to a variable which is going to be used on further lines?

thanks.

NAME
div(), ldiv(), lldiv(), imaxdiv() - integer division and remainder SYNOPSIS
DESCRIPTION
Computes the quotient and remainder of the division of the numerator numer by the denominator denom. If the division is inexact, the sign of the resulting quotient is that of the algebraic quotient, and the magnitude of the resulting quotient is the largest integer less than the magnitude of the algebraic quo- tient. If the result can be represented, the result is returned in a structure of type (defined in having members quot and rem for the quotient and remainder respectively. Both members have type and values such that quot denom rem numer. If the result cannot be represented, the behavior is undefined. Similar to except that the arguments each have type and the result is returned in a structure of type (defined in having members quot and rem for the quotient and remainder respectively. Similar to except that the arguments each have type and the result is returned in a structure of type (defined in having members quot and rem for the quotient and remainder respectively. Similar to except that the arguments each have type and the result is returned in a structure of type (defined in having members quot and rem for the quotient and remainder respectively. WARNINGS
