Sub string a variable with variable

Question

I have a .bat file that needed to substring a variable with another variable. The the substring will be inside a loop. I have two variable inside this loop.

echo %%i  

echo %targetPath%

%%i is the full string. And I have to remove part of %%i if found a match string with %targetPath%

My coding which is not working.

echo  %%i%:%targetPath%=%

My couldn't get it to work because I am confused with the %%name and %name%. This is my expected result. In php , we have a substring function that able to pass the fullstring into substring function and a keyword to be match. And this is what I trying to achieve

fullstr=abcdefghijk
keyword=abcd

result=efghijk

Current working code

setlocal EnableDelayedExpansion 

set "targetPath=%~dp0in"

for /r "%targetPath%" %%i in (.) do (

set "str=%%i"
echo  !str:%targetPath%=!

)

Current output

echo  !str:C:\Users\vuser01\Desktop\Texture Packer\libgdxtools\in=!

This type of management is fully described at [this answer](https://stackoverflow.com/questions/10166386/arrays-linked-lists-and-other-data-structures-in-cmd-exe-batch-script/10167990#10167990), although the topic is different. — Aacini, Sep 20 '17 at 14:46

you can use delayed expansion:

setlocal enableDelayedExpansion
set "target=some"
for %%i in ("something") do (
 set "var=%%i"
 echo !var:%target%!
)

can it done without a loop? I am trying to make it simple as possible as I am not familiar with writing batch. I have updated my question to provide more information – Leon Armstrong Sep 20 '17 at 06:57
@LeonArmstrong - you can.Just you mentioned that your code is withing a for loop. – npocmaka Sep 20 '17 at 07:27
echo !str:%targetPath%=! I try to use this line within the code , it is not running – Leon Armstrong Sep 20 '17 at 07:54
@LeonArmstrong do you have the `setlocal enableDelayedExpansion` line before that? – npocmaka Sep 20 '17 at 08:06
Yes I have , I edited the question to provide more information , guess I have other syntax that affect the output. – Leon Armstrong Sep 20 '17 at 08:51
