sar report to xml converter

I use sar reports for getting the statistic. It is better for me to get these reports converted to xml. I use some scripts to convert them but it takes a long time. Do you know any public scripts to convert sar report to xml in 1 -2 kicks.

sar

We have a script that uses sar -u 1 10 | awk '/Average/ { print ( $2 + $3 ) }' to get the CPU usage of a mutli engine machine. We think we are getting wrong information from the above string. We think it is adding up the total of the 12 engines and reporting back the total not the overall...

CRITICAL_ENTER(9)					   BSD Kernel Developer's Manual					 CRITICAL_ENTER(9)

NAME

     critical_enter, critical_exit -- enter and exit a critical region

SYNOPSIS

     #include <sys/param.h>
     #include <sys/systm.h>

     void
     critical_enter(void);

     void
     critical_exit(void);

DESCRIPTION

     These functions are used to prevent preemption in a critical region of code.  All that is guaranteed is that the thread currently executing
     on a CPU will not be preempted.  Specifically, a thread in a critical region will not migrate to another CPU while it is in a critical
     region.  The current CPU may still trigger faults and exceptions during a critical section; however, these faults are usually fatal.

     The critical_enter() and critical_exit() functions manage a per-thread counter to handle nested critical sections.  If a thread is made
     runnable that would normally preempt the current thread while the current thread is in a critical section, then the preemption will be
     deferred until the current thread exits the outermost critical section.

     Note that these functions are not required to provide any inter-CPU synchronization, data protection, or memory ordering guarantees and thus
     should not be used to protect shared data structures.

     These functions should be used with care as an infinite loop within a critical region will deadlock the CPU.  Also, they should not be inter-
     locked with operations on mutexes, sx locks, semaphores, or other synchronization primitives.  One exception to this is that spin mutexes
     include a critical section, so in certain cases critical sections may be interlocked with spin mutexes.

HISTORY

     These functions were introduced in FreeBSD 5.0.
