Man ... you're simply awesome!
Supose that in the future I need to change the <y> value too, with a value distinct to the x and also random the code will be this ?
Code:
awk '/x/{srand(NR);v=rand()*50+1;$0="<x>"v"</x>"};1' myfile.xml > filemod.xml
awk '/y/{srand(NR);v=rand()*50+1;$0="<y>"v"</y>"};1' myfile.xml > filemod.xml

because it doesn't give me the expected result .

Here I Post part of the exactly xml that I'm working .

Code:
<mote> 
      <interface_config> 
        se.sics.cooja.interfaces.Position 
        <x>53.39887462699737</x> 
        <y>66.79001043503861</y> 
        <z>0.0</z> 
      </interface_config> 
      <interface_config> 
        se.sics.cooja.contikimote.interfaces.ContikiMoteID 
        <id>4</id>

Thanks Again for your Time and your experience in this !

srand

rand(3UCB)					     SunOS/BSD Compatibility Library Functions						rand(3UCB)

NAME

       rand, srand - simple random number generator

SYNOPSIS

       /usr/ucb/cc [ flag ... ] file ...

       int rand();

       int srand(seed)
       unsigned seed;

DESCRIPTION

       rand()  uses a multiplicative congruential random number generator with period 2^32 to return successive pseudo-random numbers in the range
       from 0 to 2^31 -1.

       srand() can be called at any time to reset the random-number generator to a random starting point. The generator is initially seeded with a
       value of 1.

SEE ALSO

       cc(1B), drand48(3C), rand(3C), random(3C)

NOTES

       Use of these interfaces should be restricted to only applications written on BSD platforms.  Use of these interfaces with any of the system
       libraries or in multi-thread applications is unsupported.

       The spectral properties of rand() leave a great deal to be desired. drand48(3C) and random(3C) provide much better, though more	elaborate,
       random-number generators.

       The low bits of the numbers generated are not very random; use the middle bits. In particular the lowest bit alternates between 0 and 1.
