Appending string to xml file using "sed"
Hi folks,

Following a section in opmn.xml file:
Code:
</process-type>
    <process-type id="OC4J_RiGHTv_IRD1" module-id="OC4J">
        <environment>
            <variable id="LD_LIBRARY_PATH" value="/home/ias/v10.1.2/lib" append="true"/>
            <variable id="SHLIB_PATH" value="/home/ias/v10.1.2/lib32" append="true"/>
        </environment>

I need to find the line <process-type id="OC4J_RiGHTv_<SCHEMA_NAME>
Under this line find the line "<variable id="LD_LIBRARY_PATH .........."
and appending under this line :
<variable id="LD_LIBRARY_PATH" value="${ORACLE_HOME}/j2ee/OC4J_RiGHTv_${SCHEMA_NAME}/orca-3rd-lib" append="true"/>

The requested result should be :
ORACLE_HOME=/home/ias/v10.1.2
SCHEMA_NAME=IRD1
Code:
</process-type>
    <process-type id="OC4J_RiGHTv_IRD1" module-id="OC4J">
        <environment>
            <variable id="LD_LIBRARY_PATH" value="/home/ias/v10.1.2/lib" append="true"/>
            <variable id="LD_LIBRARY_PATH" value="/home/ias/v10.1.2/j2ee/OC4J_RiGHTv_IRD1/orca-3rd-lib" append="true"/>
            <variable id="SHLIB_PATH" value="/home/ias/v10.1.2/lib32" append="true"/>
        </environment>

I wrote the following function:
Code:
update_opmn_xml()
{
opmnXml=/tmp/opmn.xml
export SCHEMA_NAME=IRD1
export ORACLE_HOME=/home/ias/v10.1.2
echo "<variable id=\"LD_LIBRARY_PATH\" value=\"${ORACLE_HOME}/j2ee/OC4J_RiGHTv_IRD1/orca-3rd-lib\" append=\"true\"/>" > /tmp/append_str.lst
sed -e '/process-type id="'"OC4J_RiGHTv_${SCHEMA_NAME}"'"/,/variable id=\"LD_LIBRARY_PATH\"/r /tmp/append_str.lst' ${opmnXml} > ${opmnXml}.new

mv ${opmnXml}.new ${opmnXml}
chown ias:oinstall ${opmnXml}
}

I run the function and the final result was not as I needed:
Code:
</process-type>
            <process-type id="OC4J_RiGHTv_IRD1" module-id="OC4J">
<variable id="LD_LIBRARY_PATH" value="/home/ias/v10.1.2/j2ee/OC4J_RiGHTv_IRD1/orca-3rd-lib" append="true"/>
               <environment>
<variable id="LD_LIBRARY_PATH" value="/home/ias/v10.1.2/j2ee/OC4J_RiGHTv_IRD1/orca-3rd-lib" append="true"/>
                  <variable id="LD_LIBRARY_PATH" value="/home/ias/v10.1.2/lib" append="true"/>
<variable id="LD_LIBRARY_PATH" value="/home/ias/v10.1.2/j2ee/OC4J_RiGHTv_IRD1/orca-3rd-lib" append="true"/>
                  <variable id="SHLIB_PATH" value="/home/ias/v10.1.2/lib32" append="true"/>
               </environment>

What is my mistake in the function update_opmn_xml?

Thanks in advance,
Nir

mv ${opmnXml}.new ${opmnXml}
chown ias:oinstall ${opmnXml}
}

The above becomes

Code:
sed -e '/variable id=\"LD_LIBRARY_PATH\"/r /tmp/append_str.lst' ${opmnXml} > ${opmnXml}.new

Hey vino,

Thanks a lot for your reply!
It is close to what I need.
Let me clarify :
The string <variable id="LD_LIBRARY_PATH" value="/home/ias/v10.1.2/lib" append="true"/> appears a lot in opmn.xml so I cannot find this string and append bellow it my string.
The unique string is <process-type id="OC4J_RiGHTv_$SCHEMA_NAME" module-id="OC4J">

So ,the find steps for the sed should be:
1. Find <process-type id="OC4J_RiGHTv_$SCHEMA_NAME" module-id="OC4J">
2. Bellow the above ,find <variable id="LD_LIBRARY_PATH" value="$ORACLE_HOME/lib"
3. Under the string from step 2,append the requested string.

I hope I clarified my task.

Thanks in advance,
Nir
