  <JOB

OK I'll try to be more specific.

Can you help me with one command that deletes lines containing <QUANTITATIVE NAME="DRIVE1" QUANT="1"/> in all JOB entries when value of JOBNAME starts by JOB1. Desired output would be:

Code:
   ...
  <JOB
   ...
   JOBNAME="JOB1"
   ...
>
   <OUTCOND NAME="JOB1-OK" ODATE="ODAT" SIGN="ADD"/>
   <AUTOEDIT EXP="%%SYSTEM=server1"/>
  </JOB>
  <JOB
   ...
   JOBNAME="JOB2"
   ...
>
   <QUANTITATIVE NAME="DRIVE2" QUANT="1"/>
   <OUTCOND NAME="JOB2-OK" ODATE="ODAT" SIGN="ADD"/>
   <AUTOEDIT EXP="%%SYSTEM=server1"/>
  </JOB>
   ...


Second command: Add the line <QUANTITATIVE NAME="DRIVE2" QUANT="2"/> before </JOB> in all JOB entries when JOBNAME starts by JOB2. Desired output would be:
Code:
   ...
  <JOB
   ...
   JOBNAME="JOB1"
   ...
>
   <QUANTITATIVE NAME="DRIVE1" QUANT="1"/>
   <OUTCOND NAME="JOB1-OK" ODATE="ODAT" SIGN="ADD"/>
   <AUTOEDIT EXP="%%SYSTEM=server1"/>
  </JOB>
  <JOB
   ...
   JOBNAME="JOB2"
   ...
>
   <QUANTITATIVE NAME="DRIVE1" QUANT="1"/>
   <OUTCOND NAME="JOB2-OK" ODATE="ODAT" SIGN="ADD"/>
   <AUTOEDIT EXP="%%SYSTEM=server1"/>
   <QUANTITATIVE NAME="DRIVE2" QUANT="2"/>
  </JOB>
   ...

Once again thanks for for your great help! Smilie
