Shell Programming and Scripting

Hi all,

I have an xml file which have several sections as the following:

<process-type id="NIR" module-id="OC4J">
<module-data>
<category id="start-parameters">
<data id="java-options" value="-server -Djava.security.policy=/home/ias/v10.1.2/j2ee/NIR/config/java2.policy -Djava.awt.headless=true"/>
<data id="oc4j-options" value="-properties"/>
</category>
<category id="stop-parameters">
<data id="java-options" value="-Djava.security.policy=/home/ias/v10.1.2/j2ee/NIR/config/java2.policy -Djava.awt.headless=true"/>
</category>
</module-data>
<start timeout="900" retry="2"/>
<stop timeout="120"/>
<restart timeout="720" retry="2"/>
<port id="ajp" range="3301-3400"/>
<port id="rmi" range="3201-3300"/>
<port id="jms" range="3701-3800"/>
<process-set id="default_island" numprocs="1"/>
</process-type>

Each section start with <process-type id="NIR" module-id="OC4J">
($SCHEMA_NAME=NIR) and ends with </process-type>

I need to substitute the range ports in the lines:
<port id="rmi" range="3201-3300"/>
<port id="jms" range="3701-3800"/>

I cannot do it with sed globally because it will substitute all the appearances in the file.
I can find the first line by grepping: process-type id=\"$SCHEMA_NAME\"
After that going down 14 lines and 15 lines and substituting the ports.

The question is : does "sed" know to get line number and replace the string in the specific line?

Thanks in advance,
Nir

You can sed for

port id="ajp" and port id="rmi"

and then on those lines, you can make your changes.

Code:

sed -n -e 's/\(.*"ajp".*\)[0-9][0-9]*\(-\)[0-9][0-9]*\(.*\)/\11025\28000\3/g' inputfile

I have changed the port range for "ajp" from 3301-3400 to 1025-8000.

Those appearing as red are the matched pattern in the regex. indicated as \(...\)

Another thing, which you will have to do is the escaping of the " in the regex.

Hi vino,

Thanks for your reply but you missed someting.
The problem that the section :
<port id="ajp" range="3301-3400"/>
<port id="rmi" range="3201-3300"/>
<port id="jms" range="3701-3800"/>

apears a lot in the xml file.

I need to isolate first the requested section by finding 14 lines above the $SCHEMA_NAME and locate the line number.
e.g:
lineNum=`grep -n "process-type id=\"${SCHEMA_NAME}\"" opmn.xml`
RmiLineNum=lineNum+14 (The line port id="rmi" range="3201-3300 is permanently apears 14 lines later after the line : process-type id=\"${SCHEMA_NAME}\"

And finally,I want to take line $RmiLineNum and substituting there.

How to do it?

Thanks again.
Nir

Code:

sed '/process-type id="'"$SCHEMA_NAME"'"/,/<\/process-type>/{ /<port id="rmi"/s/foo1/bar1/; /<port id="jms"/s/foo2/bar2/; }'

Hey r2007,

Thanks a lot!
It works fantastic!!

Best regards,
