How to escape I/O redirect characters in cmd?

Question

PowerShell

I have a file.txt which contains:
< Hello World >
How can I extract the string Hello World from this file without special characters?

The file cannot be read and truncated due to I/O redirection characters ( < and > ).

I know there's an escape character ^, but it doesn't really help when reading a line from a file.

Answer 1

((get-content C:\test\hello.txt) -replace "[^a-zA-Z0-9 -]").trim()

Answer 2

You can also use CMD if you wish :)
something like that

for /f "tokens=*" %%a in ('type "test.txt"') do (
  call :extract "%%a"
)
goto :EOF
:extract
set l=%1
@set "line2=%l:~2,-2%"
echo %line2%
goto :EOF
