I found the solution in the below link and it worked. Why is my post-commit hook conditional statement not working when I check to see if a particular branch was committed?
svnlook dirs-changed %1 -r %2 | findstr /b /i "branches/dev"
IF %ERRORLEVEL% EQU 0 (
pushd <path-to-working-copy>
svn update --username <repo-username> --password <repo-password>
)
in the place of "branches/dev". I replaced with my path "/Mobile/Node/trunk"
