Hi RudiC

Thanks for the quick reply.

I meant the value is empty.

I tried with
Code:
<timestamp1>..*</timestamp1>

and I am able to get the count if it having null values.

But if the log file is having an empty value for timestamp1 then i have to pull the entire xml and insert current time to that empty xml field.

Sample xml:
<submit>
<ID>16</ID>
<Reference/>
<timestamp1></timestamp1>
....
.....
</submit>

Could you please help me to do this.

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
