for /f command : special delims character

[refigh]

Hi,
I wanted to use for /f command to parse a file. one of delimes
character used to separate the words is " character. (plus character
_ ). but for command does not accept it :
for /f "tokens=1-6 delims=_"" %%i in ("%%a") do ( ......
produces error.
how can I assign character " as delims?

[Timo Salmi]

One way around it is first to replace the " characters with a more
delims-tolerant character. Somewhat along the lines of e.g.

34} How can I remove the quote characters from a line?

All the best, Timo

You can optionally shows us some of the text and explain what you need to parse. There are some ways to get around this, depending on the text layout.

I think first solution of your link is good for me, but I have a
problem,
set command does not work in for /f..... do ( ) why?
for example, below line print "test" not "test2"

@echo off
set VERSION_SRC=XilinxPrj\Embed_proc_AXI\pcores\version_v1_00_a\hdl
\vhdl\user_logic.vhd
set line_=test

for /D %%d in ( ???_? ) do (
for /f "tokens=5-12 delims=;_X " %%i in ('findstr /I /R /
c:"hw_version_brch.*<=.*" %%d\%VERSION_SRC%') do (
set line_=test2
echo. %line_%
)
)
@echo on

You have to declare:

setlocal ENABLEDELAYEDEXPANSION

and use:

echo. !line_!

instead of

echo. %line_%

thank you man
It is solved

echo( should be prefered against echo., as it is ~10 times faster and
more robust.

To use a quote character as a delim character in a FOR /F loop is
posible,
it only looks a bit ugly.

setlocal EnableDelayedExpansion
set "var=one"two"three"
FOR /f tokens^=1-3^ delims^=^" %%a in ("!var!") do echo %%a--%%b--%%c

FOR /f tokens^=1-3^ delims^=^" %%a in ("!var!") do echo %%a--%%b--%%c

????

I'm not sure whether I'm more astonished that this works or that someone
would attempt to use such "obviously-broken" syntax.

(but the escaped-space after the "3" is redundant. If the superfluous space
exists, it must be escaped however...)

[billious]

On further experimentation, I found that to specify a number of separators
for DELIMS

1. standard characters may but need not be escaped by ^
2. ^[space] must be last, if it used
3. = and & and ^ require to be escaped by ^
4. % needs to be escaped by %

(testing incomplete)

[jeb]

The space behind the 3 may be superfluous, but normally you add it to
the options like
FOR /F "tokens=1-3 delims=X" looks better than FOR /F
"tokens=1-3delims=X"

The syntax is a bit compliacated as all the standard delims for a
batch line are active there ;,=<space> and <tab>
Obviously the special characters like ^&|<> have to be escaped
Ther percent must always be escaped, even if it is in a `normal`
quoted option string.

I build a similar string for disabling the EOL character (which can't
be empty), by setting it to the line feed character.

for /f ^"tokens^=1-3^ eol^=^

^" %%a in (myFile) do ...

The line break is necessary for inserting the LF.
But even if I used the "escaping" syntax I never got the idea to
remove the quotes completly, and with the surrounding quotes you can't
set the delims to the quote character.

Good. You might also find the following of some interest

Yes, but now it's outdated.
With using directly the quotes as delims the workaround is no longer
necessary

Yes, a time ago I tested it with FOR /L, the following lines are doing
excactly the same,
as only the delims are necessary while parsing, the rest will be
ignored

FOR /L %%n in (1,1,10) DO echo %%n
FOR /L %%n in (1 1 10) DO echo %%n
FOR /L %%n in (1;1;10) DO echo %%n
FOR /L %%n in (1=1=10) DO echo %%n
FOR /L %%n in (1;,,;==,,; 1;=,,;;==;,;;10) DO echo %%n
FOR /L %%n in (1+Pi/2=1-sin(360°^)=10E-20*array[4]) DO echo %%n

I have to disagree with such a categoric assessment. Esoteric,
undocumented tweaks do not outdate the more regular solutions in the
true sense of the word.

But they can be useful and certainly are highly interesting, even
intriguing.

All the best, Timo
