Replace entire line cmd - batch-file

Question

I have a file where I search for a specific text and want to replace it with another. For example:
<role-name>test</role-name>
this is for example what I want to replace it with:
<role-name>file</role-name>
The problem here would be that in the <role-name> tag might be other text then "test".
How can I find the whole line and replace it with the text that I need?
Or maybe I can retrieve the line number of the tag and replace it whole, but again I have no idea how to do that :-)

Answer 1

The key to doing this without external code is using the string substitution expression. I assume you want to parameterize the tag and value strings. This would also depend on the sequence not having any newline characters.
C:>type seb.bat
#ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET EXITCODE=0
SET "TAG=%~1"
SET "FROMVAL=%~2"
SET "TOVAL=%~3"
FOR /F "usebackq tokens=*" %%a IN (`TYPE "seb.html"`) DO (
echo %%a
SET S1=%%a
SET S2=!S1:^<%TAG%^>%FROMVAL%^</%TAG%^>=^<%TAG%^>%TOVAL%^</%TAG%^>!
ECHO !S2!
)
EXIT /B %EXITCODE%
C:>type seb.html
<role-name>test</role-name>
C:>seb role-name test file
<role-name>test</role-name>
<role-name>file</role-name>
<role-name></role-name>
<role-name></role-name>
C:>seb role-name test ""
<role-name>test</role-name>
<role-name></role-name>
<role-name></role-name>
<role-name></role-name>
C:>seb role-name "" "file"
<role-name>test</role-name>
<role-name>test</role-name>
<role-name></role-name>
<role-name>file</role-name>

Answer 2

The problem was that I was reading from a file and the string that I wanted to compare came in a for loop. This is my code that reads from file and writes the code that I needed, if anyone needs it :
set "nameofapp=%<display-name>"
set "nameofapp_country=% <display-name>ASD</display-name>"
set "rolename=%<role-name>"
set "rolename_country=% <role-name>ASD-role</role-name>"
set "propertiesfile=%<env-entry-value>"
set "properties_file=% <env-entry-value>java-asd.properties</env-entry-value>"
set "web=src\main\webapp\WEB-INF\web.xml"
set "web_1=web.xml"
(for /f "delims=" %%i in (%web%) do (
set "line=%%i"
setlocal enabledelayedexpansion
set "name=!line:%nameofapp%=%!"
if not !name! == !line! (
set "line=%nameofapp_country%"
)
set "role=!line:%rolename%=%!"
if not !role! == !line! (
set "line=%rolename_country%"
)
set "property=!line:%propertiesfile%=%!"
if not !property! == !line! (
set "line=%properties_file%"
)
echo(!line!
endlocal
))>"%web_1%"
del %web%
Move %web_1% "src\main\webapp\WEB-INF\"
