Java Replacing multiple lines in file from another file

Hi All,
I'm trying to parse a XML file and replace few lines of file with text present in another file. But only issue is I need to replace only those lines from XML which are preceeding the JOBNAME =*RRN*
For ex test.xml(content of XML file in which I want to replace lines is )
Code:
<JOB
.
.
.
JOBNAME="JD901_001__CTM_APPLICATION__PRD1Q"
.
.
>
<ON CODE="*" STMT="*" >
 <DOSYSOUT PAR="%%USREP.%%JOBNAME._%%RUNCOUNT..log" OPTION="Copy" />
    </ON>
    <ON CODE="COMPSTAT&lt;03" STMT="*" >
     <DO ACTION="OK" />
    </ON>
 <ON CODE="NOTOK" STMT="*" >
     <DOSHOUT DEST="ECS" MESSAGE="ERROR ON JOB %%JOBNAME" URGENCY="R" />
    </ON>
</JOB>
<JOB
.
.
JOBNAME="JD901_001__RRN_APPLICATION__PRD1Q"
.
.
>
    <ON CODE="*" STMT="*" >
     <DOSYSOUT PAR="%%USREP.%%JOBNAME._%%RUNCOUNT..log" OPTION="Copy" />
    </ON>
    <ON CODE="NOTOK" STMT="*" >
     <DOSHOUT DEST="ECS" MESSAGE="ERROR ON JOB %%JOBNAME" URGENCY="R" />
    </ON>
</JOB>

Now I want to replace only lines starting from <ON CODE="*" STMT="*" >
to </JOB> only where I could find
JOBNAME="JD901_001__RRN_APPLICATION__PRD1Q".

Replace.txt ( File containing the text I want to replace it with)
Code:
 <ON CODE="*" STMT="*" >
     <DOSYSOUT PAR="%%USREP.%%JOBNAME._%%RUNCOUNT..log" OPTION="Copy" />
     <DO ACTION="RERUN" />
    </ON>
    <ON CODE="*" STMT="*" >
     <DO ACTION="OK" />
    </ON>
    <ON CODE="NOTOK" STMT="*" >
     <DOSHOUT DEST="ECS" MESSAGE="ERROR ON JOB %%JOBNAME" URGENCY="U" />
    </ON>

I used grep to serach all the occurances of RRN jobs
Code:
grep -n 'JOBNAME=*.*RRN*' text.xm

l and using line numbers I tried to search in XML to replace the lines, but its not working.

Can somebody please help me with this.

Thanks

Try:
Code:
perl -0pe 'BEGIN{open I, "Replace.txt";$b=<I>};s/(<JOB[^>]*RRN[^>]*>\n).*?<\/JOB>/\1$b<\/JOB>/gs' test.xml > out.xml

Hi Bartus11 thanks for your reply, but I don't know PERL. Can somebody guide me in Unix

Old 06-05-2011
But did you try my command? Did it work...? Perl IS one of the Unix commands.

Yes I tried the command, it did replace the lines. But it has removed some of the required lines also Smilie, sorry I forgot to mention in my previous example that before <ON CODE="*" STMT="*" >(From where I want to start the replacement) there are few lines which I don't want to replace.

<Job
.
.
JOBNAME="JD901_RRN__CTM_APPLICATION__PRD1Q"
.

<INCOND ..... />
<OUTCOND..../>

<ON CODE="*" STMT="*" >
<DOSYSOUT PAR="%%USREP.%%JOBNAME._%%RUNCOUNT..log" OPTION="Copy" />
</ON>
<ON CODE="NOTOK" STMT="*" >
<DOSHOUT DEST="ECS" MESSAGE="ERROR ON JOB %%JOBNAME" URGENCY="R" />
</ON>
</JOB>

Could you please help me with this? Thanks

Try:
Code:
perl -0pe 'BEGIN{open I, "Replace.txt";$b=<I>};s/(<JOB[^>]*RRN[^>]*>\n([^\n]*\n){3}).*?<\/JOB>/\1$b<\/JOB>/gs' test.xml > out.xml

Thanks Bartus

Could you please explain to me what exactly this command is doing? what if I want to keep more than 3 lines before the replacement starts ,Then what should I do?
Lines before the (<ON CODE="*" STMT="*" >) replacement starts is dynamic , I can't put the static number.

s/(<JOB[^>]*RRN[^>]*>\n([^\n]*\n){3}).*?<\/JOB>/\1$b<\/JOB>/gs
