How do I handle these

---------- Post updated at 10:51 PM ---------- Previous update was at 10:43 PM ----------

I understand If I use single qoutes I will be able to handle it but I want to pass the string as a variable and when I use single qoutes it may not expand the variable
You are correct in saying that variables will not be expanded when they appear inside single quotes. Since there are no variables in your example I don't know what you're trying to do.

The sed command above will perform the same as any of the following:
Code:
sed -e "s|xmlns=123//abc/integration/||g" Orginal.xml >output.xml
sed -e 's|xmlns='123//abc/integration/'||g' Orginal.xml >output.xml
sed -e 's|xmlns=123//abc/integration/||g' Orginal.xml >output.xml
sed -e s"|"xmlns=123//abc/integration/'||'g Orginal.xml >output.xml

or several million other commands with other combinations of single and double quotes. If you will clearly describe where you want to put a variable and explain what is in the variable, we may be able to help.

If you are hoping to set a shell variable to a string matched by a pattern given in a sed substitute command, the syntax you are using is VERY strange and will not work in that form.

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

HISTORY

       The GNU shtool subst command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 2001 for GNU shtool.  It was prompted
       by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.

SEE ALSO

       shtool(1), sed(1).
