Extracting filenames from svn console output

Question

My Tortoise SVN SVN update command generally returns me this output:

C:\proj>svn update
Updating '.':
A 'some-file1.txt'
D 'some-file2.txt'
Restored 'some-file3.txt'
U 'some'file4.txt'
C 'some file5.txt' B
At revision 123.

Please note that except for the first line (always starting with Updating) and last line (always starting with At), each line will always have:

• an action in the first column. This can be a letter or a word
• a file in the second column, wrapped in single quotes. Unfortunately filenames can contain single quotes or whitespaces within them!
• possibly more columns with single letters in them. But I don't care about them.

In a batch file that I am writing, I need to have the actions and files. The actions I manage to get, but the files are too tricky for me it seems. Technically, all I want is everything between the first single quote and the last single quote on the line.

@echo off
setlocal enabledelayedexpansion
for /f "delims=" %%a in ('"svn update"') DO (
    set line=%%a
    for /f "tokens=1" %%b in ("!line!") do (
        set action=%%b
        if "!action!" neq "Updating" (
            if "!action!" neq "At" (
                set file= >>> I DON'T KNOW WHAT TO DO HERE <<<
                echo We did !action! to !file!
            )
        )
    )
)

Once this batch file is working correctly, it should output:

We did A on some-file1.txt
We did D on some-file2.txt
We did Restored on some-file1.txt
We did U on some'file1.txt
We did C on some file1.txt

I seem to have found a solution with powershell, by replacing the set file= line with the following

for /f "delims=" %%c in ('"C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe -Command ""$Env:line -replace '^^[^^'']*''' -replace '''[^^'']*$'"" "') DO (
    set file=%%c
)

Powershell takes the %line% (there it is called $Env:line), and replaces ^[^']*' with nothing, and replaces '[^']*$ with nothing, and returns the string which is then caught with for /f again and put into %file%
