Extract after delimter in a text file with Batch - string

I have been searching for hours, however most of the results give examples that deal with directories. I need to read a text file to achieve this and extract after the last \ and output into a new file
Below is what my file contains in a text file
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\yahoo.com
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\NYU.edu
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\openssl.org
I need to extract all the different strings after the last \ in the string. How do I go about doing this?
I tried this one but it is not working properly Extracting string after last instance of delimiter in a Batch file
This is on Windows 7 x64 SP1 and I can't install other software to achieve this either.

This should work:
#ECHO OFF
SETLOCAL EnableDelayedExpansion
SET inFile=C:\SomePath\someFile.txt
SET outFile=C:\SomePath\anotherFile.txt
TYPE NUL>%outFile%
FOR /F "tokens=*" %%L IN (%inFile%) DO (
ECHO %%~nxL>>%outFile%
)
You'll have to replace inFile and outFile with proper paths. If they contain spaces, surround them with quotation marks.
%outFile% will always be overwritten so make sure you don't loose your data!

Batch File - Add Extension to Strings in a .txt File

I am trying to get this batch file to work but not sure exactlty what to do from here...
What I need is to have a batch file add extensions to multiple text strings that have special characters in half of them, then output to new txt file.
With this batch the way it is now, it will add the extension to the strings in the text file, and also output the new txt file, but will pass on the one's that have special characters.
Here is what I have:
#echo off
setlocal EnableDelayedExpansion
set addtext=.jpg
for /f "delims=*" %%a in (list.txt) do (echo/|set /p =%%a%addtext% & echo\)
>>new_list.txt
Any Help is Over Appreciated!
THANKS...
Would
for /f "delims=*" %%a in (list.txt) do (echo(%%a%addtext%)>>new_list.txt
Do what you want?
Without examples of what's on your input file and what you require on the output, we have to analyse the code for what's in your head - and remember, what's in your code doesn't do what's in youir head. If it did, you wouldn't be asking your question.

Remove empty lines from a preformatted CSV

im generating a CSV from an XLS file with VBA, after that I am filtering the CSV with Batch. My filter looks like this:
for %%a in (*.csv) do (
for /f "usebackq tokens=1-10 delims=, eol=^" %%1 in ("%%a") do (
if %%4 EQU Req_Category ECHO %%1,%%2,%%3,%%4,%%5,%%6,%%7,%%8,%%9 >> "%%a"_JIRA.csv
if %%4 EQU Requirement ECHO %%1,%%2,%%3,%%4,%%5,%%6,%%7,%%8,%%9 >> "%%a"_JIRA.csv
)
)
This works fine if the CSV File has no empty lines.
In rare occasions the XLS -> CSV converting generates empty lines or CRs in the CSV.

SW_Fn-166,4.2,Compliance Requirements,Heading,,,,,IgnoreTesting,
SW_Fn-286,4.2.1,Resource Usage,Heading,,,,,IgnoreTesting,
Every line in the CSV should start with an ID: SW_Fn-Example.
Does every one have an idea how can bring the info on one line with a batch function?
I need to get the file to look like this (before filtering):
SW_Fn-289,4.1.1.1,Controling Hardware PCB,Heading,,,,,IgnoreTesting,
SW_Fn-291,4.1.1.1.0-1,"Date : 07.03.1777 TheSystemDesignSpecificationisstored in SVN path http://sblablablabla.xlsm",Requirement,Lab1 (B-Sample),,Released,Accepted,IgnoreTesting,
SW_Fn-4281,4.1.1.1.0-2," Date : 123.123.123 Path : https://apath.com",Requirement,R1,,New,New,IgnoreTesting,
SW_Fn-166,4.2,Compliance Requirements,Heading,,,,,IgnoreTesting,
SW_Fn-286,4.2.1,Resource Usage,Heading,,,,,IgnoreTesting,
There shouldnt be a line that does not start with SW_Fn-blabla. If a line starts with something else, then it should be a part of the previous line that has an Sw_Fn-blabla.
Then my filter will work to produce this:
SW_Fn-291,4.1.1.1.0-1,"Date : 07.03.1777 TheSystemDesignSpecificationisstored in SVN path http://sblablablabla.xlsm",Requirement,Lab1 (B-Sample),,Released,Accepted,IgnoreTesting,
SW_Fn-4281,4.1.1.1.0-2," Date : 123.123.123 Path : https://apath.com",Requirement,R1,,New,New,IgnoreTesting,
Thanks in advance
try this:
#echo off
for %%a in (*.csv) do (
for /f "delims=" %%b in (%%a) do (
for /f "tokens=4 delims=," %%c in ("%%b") do (
if "%%c"=="Requirement" echo %%b >>%%~na_JIRA%%~xa
if "%%c"=="Req_Category" echo %%b >>%%~na_JIRA%%~xa
)
)
)
read and handle each line complete to overcome the consecutive-delimiter-issue mentioned by Magoo (use another for to check Token4, but don't bother to disassemble and reassemble the complete line)
Aak! don't use numerics for the metavariable (%%1) - it's highly unreliable. Use an alphabetic character.
Batch treats a string of delimiters as a single delimiter and you have nominated commas and spaces as delimiters, so
SW_Fn-166,4.2,Compliance Requirements,Heading,,,,,IgnoreTesting,
would appear as
SW_Fn-166,4.2,Compliance,Requirements,Heading,IgnoreTesting,,,,
You haven't shown what you expect as output. Do you only want the lines that begin SW_Fn- or do you want all lines that don't start SW-Fn appended to the last line that did?
#ECHO Off

You would need to change the settings of sourcedir and destdir to suit your circumstances.
I used a file named q36475816.csv containing your data for my testing.
Produces the file defined as %outfile%
Note that your posted data contains unbalanced quotes in the Fn-4281 item. It's always better to use actual data rather than "somewhere close".
Read each line. If we've already accumulated part of a line, check whether the first few characters are the target. If they are, output the line as constructed and clear line.
If line is clear after this operation, set it to the line read (which must startwith the target, otherwise accumulate the line.
In the :test procedure, remove quotes before testing so that it doesn't break the syntax. Obviously, if the first few characters contains a quote, it doesn't fit the target so the test will correctly detect "no fit"
Your file is actually valid CSV format. Quoted CSV fields may contain any of the following:
comma
quote literal, escaped as ""
newline (either LF or CRLF)
You don't have commas or quotes within your fields, but you do have newlines that are giving your code serious problems.
But that is only one potential problem. Another issue is FOR /F treats consecutive delimiters as a single delimiter, so if any of your desired keeper lines have any empty fields, then your output will be completely wrong.
Batch is inherently far from ideal for any kind of text processing, but for CSV it is especially bad for all but the most simplest problems. If you really want to use batch, you could use ParseCSV.bat to properly parse your CSV and read it using FOR /F in a reliable manner. But there are better options.
PowerShell has an Import-Csv cmdlet. I'm not sure of its capabilities, but if it supports newlines within fields, then you could develop a really slick solution with that.
Another option is my JREPL.BAT regular expression text processor. The following code looks nasty, but it will very efficiently produce your desired output in one step:
jrepl "((?:[\s\S]*?,){3}(?:(Req_Category,|Requirement,)|.*?,)(?:.*?,){4}.*?),[^,\n]*\n?" "$2?$1.replace(/\r\n/g,' ')+'\r\n':''" /m /j /f input.csv /o output.csv
You would need to use CALL JREPL if you put the command within another batch script.
My JREPL solution relies on the fact that none of your input fields contain quoted commas. If it did contain quoted commas, then a JREPL solution would be even more complicated.
This solution works by using the /M multiline option so that I can match across line-breaks.
The search matches each 10 field collection (your 10th field seems to be always empty), regardless of line breaks. $1 contains the first 9 fields (without the trailing comma). $2 contains the 4th field if and only if it matches "Req_Category" or "Requirement". The replacement javascript expression tests if $2 is defined, and if it is, then the whole search expression is replaced with $1 after all newlines have been replaced by spaces, and then a newline is appended. IF $2 is not defined then the whole search expression is replaced with an empty string. Simple in concept, but kind of nasty to develop ;-)
A slight simplification allows you to preserve the original fields containing newlines, and still do the filtering you desire.:
jrepl "((?:[\s\S]*?,){3}(?:(Req_Category,|Requirement,)|.*?,)(?:.*?,){4}.*?),[^,\n]*\n?" "$2?$1+'\r\n':''" /m /j /f input.csv /o output.csv

shorten every line in a text file by exactly 59 charaters then add a new shorter string in their place

For something so simple that can easily be done with find replace in notepad, I can't see why it is so hard to do in a command line as it is just one step in the entire procedure that I would like to get down to a single run. The output from the first part lists the local path to all the websites in the webserver as the each local path c:/ etc. every site has the same 59 characters before the part that matters.
To make this a usable link, I need to then add a different string in the same position as the old one with the correct http://. etc. to the balance of the line to make it a working hyperlink.
The final step needs to convert any single "\’s" that are left to a "/". Normally there is only one
All of this can be done in notepad++ using find and replace but it takes 3 runs to achieve the end result the original text file is nothing special, no skipped lines, everyone is identical in layout.
The same 59 characters need to be chopped off (it could even be by Number and not by comparing the text, just shorten by 59 characters if that is easier. The replacement text string is always exactly the same that just gets appended to each line. And for the final touch of replacing every \ with a / to make it fully web-compatible there is only one occurrence on each line.
I have seen many find and replace batch-files that seem to be overkill for such a simple task.
Take each line, count fifty nine characters forward, chop off the 59 and add in the replacement text in its place.
Then change the only backslash in the line to a forward slash and it’s done
Does anyone know a simpler easier way to do this
This uses a helper batch file called repl.bat - download from: https://www.dropbox.com/s/qidqwztmetbvklt/repl.bat
Place repl.bat in the same folder as the batch file or in a folder that is on the path.
Just change http://www.domain.com/ to what you need to prefix the lines with.
type "file.txt" | repl "\\" "/" | repl "^.{59}" "http://www.domain.com/" >"newfile.txt"
The two \\ are intentional as it is a regular expression.
#ECHO OFF
SETLOCAL
(
FOR /f "delims=" %%a IN (Q21495128.txt) DO (
SET "line=%%a"
CALL SET "line=%%line:\=/%%"
CALL SET "line=replacement text%%line:~59%%"
FOR /f "tokens=1*delims==" %%x IN ('set line') DO ECHO %%y
)
)>newfile.txt
GOTO :EOF
where Q21495128.txt was my test source file worked for me.

Batch file name string concatenation

this problem has been bothering me for hours. I hope someone could help shed some light. Basically, I am trying to scan through all the files (of a specific type) in a folder (there are no subfolder inside, so no need to worry this case), get those files' name, and concatenate all into one string for example, if a folder has two files,
a.xml, b.xml and c.xml, I want to get a string looks like
-a a.xml -a b.xml -a c.xml
Below is my code.
copy *.xml C:\FTP
setLocal Enabledelayedexpansion
set "directory=C:\temp"
set "attachment= "
set "a= -a "
for %%n in (%directory% *.xml) DO (
set "attachment=!attachment! %a% %directory%\%%n "
echo.%attachment%
)
setlocal disabledelayedexpansion
echo.%attachment%
The output is shown in this image http://imgur.com/vpUUe05
the problem I have is that first,
all echoes in the for loop prints out nothing. as shown in those blank lines.
the final string I want,i.e. attachment, contains an initial substring of
-a C:\temp\C:temp.
This is actually not a file. the final string I want should be one that is without this substring, only those behind it. By the way, if there is no file inside the folder, I want the string "attachment" to just an empty string like "". Can anyone help me? Thanks a lot!
Inside your for loop you show the value of %attachment%, so that value is NOT updated in each iteration; you must use delayed expansion to do so.
The set of values in for command is: (%directory% *.xml) that is, the value C:\temp and all files with .xml extension, that I assumed is none in current directory. After that, you use this value in %a% %directory%\%%n expression, so the result is -a C:\temp\C:\temp. I think there is not a point here.
If you want not the folder value in the list, just don't insert it and use %~NXn modifier in the for replaceable parameter.
Below is the correct code:
copy *.xml C:\FTP
setLocal Enabledelayedexpansion
set "directory=C:\temp"
set "attachment= "
set "a= -a "
for %%n in ("%directory%\*.xml") DO (
set "attachment=!attachment! %a% %%~NXn "
echo.!attachment!
)
setlocal disabledelayedexpansion
echo.%attachment%

best way to extract a string from a BATCH of files

i have to process 300+ HTML files, extract a string from each one and place it in a separate text file for import downstream. upside: the string format is identical in each file and is +/- two lines from the same position as well.
i thought maybe using Python, but then i thought PERL might be a better way since this kinda plays to it's backyard.
sadly, i have no access to UNIX/LINUX or i'd just grep it...
this is such an odd client request that i'm a bit goggle-eyed ATM.
so: what is the best way to extract a target string from a BATCH of files?
WR!
If you give us more details (i.e. path and name of the files, the string you want to extract, etc) perhaps I may write a Windows Batch .BAT file to achieve this task...
EDIT
To write a Batch file that successfully run I need a couple additional data, so I made some assumptions. You may help me to fix the details. This is my method:
Seek for a line that contains ">Text link<". I suppose there is just one; this may be fixed.
Read the next line. I assumed that each td is located in independent lines; this may be fixed.
In this line remove the text from beginning of line until value string.
Replace quotes by $ (the next step cannot process quotes).
Get the text between $; this is the result.
for /F skip... command may read a wrong line if thefile contains empty lines; this may be fixed.
#echo off
setlocal DisableDelayedExpansion
findstr /n ">Text link<" thefile.htm > linefound.tmp
for /F "delims=:" %%a in (linefound.tmp) do set lineNo=%%a
for /F "skip=%lineNo% delims=" %%a in (thefile.htm) do (
set "theLine=%%a"
goto continue
)
:continue
setlocal EnableDelayedExpansion
set theLine=!theLine:*value=!
set theLine=!theLine:"=$!
for /F "tokens=2 delims=$" %%a in ("!theLine!") do set URL=%%a
echo Result: %URL%
EDIT no. 2
You are confusing me. Worked the first code or not? The second example you posted in the comments seems not be related to the first one (is the data within second <td> or after [url=http://?). Is it the same problem or a different one? Please, don't assume I know about HTML file format (I don't). I DO know about Batch files, but I can't guess what to do if I have not complete details...
The following Batch file show everything between square brackets that comes IN THE SAME LINE that have the [url=http:// string in the file given in the first parameter:
#echo off
for /F "tokens=2 delims=[]" %%a in ('findstr /n "[url=http://" %1') do echo %%a
As you're already familiar with Grep, why not use a Windows port, such as the Grep in GnuWin32?
Another great way to get a ton of *nix functionality in Windows is Cygwin http://www.cygwin.com
