Oracle Commenting Multiple lines in XML file using Shell Script
I have an xml file which has following code :

Code:
 <abc-ref> 
     <abc-name>abc.efg.hij.klm</abc-name> 
  </abc-ref>

I want to comment this whole section out and I have written the following script : (where "hij" is unique string in the file)

Code:
TEMPFILE=replaceYY.tmp
file=hello.xml
sed -n '1h;1!H;${;g;s@<abc-ref.*hij*</abc-ref>@<!--Nothing-->@g;p;}' $file > $TEMPFILE
mv $TEMPFILE $file

But it is not working for me! Any help please..

How about something like:
Code:
sed '/abc-ref/,/abc-ref/s/^/# /' file

Code:
sed '/abc-ref/,/abc-ref/s/^/# /' file

This code puts # in front of every line.
Firstly I want to comment only this section out, something like
Code:
<!--abc-ref> 
     <abc-name>abc.efg.hij.klm</abc-name> 
  </abc-ref-->

Since it is an xml file # will not work here.
Also there are more than one <abc-ref> tags, so I wanted to use "hij" string to make the shell script pattern unique.

Any pointers? This is quite an easy question for experts I guess! Smilie

abc.efg.hij.klm is the only one getting commented out? SmilieSmilie

Try this (relying on your sed's capability to interpret EREs):
Code:
$ sed -r '/<abc-ref>/ {N;N;/hij/ {s#(abc-ref)#!--\1#; s#(/abc-ref)#\1--#}}' file
 <abc-ref> 
     <abc-name>abc.efg.saw.klm</abc-name> 
  </abc-ref>
 <!--abc-ref> 
     <abc-name>abc.efg.hij.klm</abc-name> 
  </abc-ref-->
 <abc-ref> 
     <abc-name>abc.efg.yxz.klm</abc-name> 
  </abc-ref>
