How to get the number after fail in a string inside a file

[goodywp]

Hi
I got a file (test.txt) which contain a string as below: (Actually it is one line below is word wrap)
window.output["stats"] = [[{"elapsed":"01:03:51","fail":8,"label":"Critical Tests","pass":56},{"elapsed":"01:03:51","fail":8,"label":"All Tests","pass":56}],[],[{"elapsed":"01:04:00","fail":8,"id":"s1","label":"AXIUM_DX8000_A591-09198-0101000_04381_CHC_00413","name":"AXIUM_DX8000_A591-09198-0101000_04381_CHC_00413","pass":56},{"elapsed":"00:02:21","fail":0,"id":"s1-s1","label":"AXIUM_DX8000_A591-09198-0101000_04381_CHC_00413.CHC Initialisation","name":"CHC Initialisation","pass":3},{"elapsed":"00:27:19","fail":0,"id":"s1-s2","label":"AXIUM_DX8000_A591-09198-0101000_04381_CHC_00413.Chase Manual Entry","name":"Chase Manual Entry","pass":28},{"elapsed":"00:33:04","fail":8,"id":"s1-s3","label":"AXIUM_DX8000_A591-09198-0101000_04381_CHC_00413.Chase Swipe Card","name":"Chase Swipe Card","pass":24},{"elapsed":"00:01:16","fail":0,"id":"s1-s4","label":"AXIUM_DX8000_A591-09198-0101000_04381_CHC_00413.CHC auto settlement","name":"CHC auto settlement","pass":1}]];

The position of "fail" should be same but the failed number can be two digits (above example is 8 ).
How can I get this failed number from the above string ?
If I use Extract a Substring by Position I come across the failed number could be two digits..
Other than that I can not think any better way to extract this failed number ?

If you're sure that the number is always at the same position, read two characers, and if the second is a comma, use only the first.
You know what, this is already ugly (you should rather use a JSON processor). So, let's make it even worse ...

Code: Select all

<"test.txt" set /p "line="
2>nul set /a "num=%line:~56%"

SET /A stops at the first character which can't be converted to an integer. Using 2>nul we ignore the error message that we get in this case.

Or selecting only a line matching that which you've posted, and regardless of the postition or the number of digits…

Code: Select all

@Echo Off & SetLocal EnableExtensions DisableDelayedExpansion
Set "failNumber=" & For /F "Delims=" %%G In ('%SystemRoot%\System32\findstr.exe
 /IRC:"window\.output\[\"stats\"\] = \[\[{.*\"fail\":[0123456789][0123456789]*,"
 "test.txt" 2^>NUL') Do (Set "matchedLine=%%G" & SetLocal EnableDelayedExpansion
	For /F "Delims=:," %%H In ("!matchedLine:*"fail"=!"
	) Do EndLocal & Set "failNumber=%%H")
Set failNumber 2>NUL
Pause & EndLocal & GoTo :EOF

As to my understanding, it's only one long line, Compo ¯\_(ツ)_/¯

Clearly and simplicity instead of ugly and most important it works. I tested 8 cases and works very well.

	) Do EndLocal & Set "failNumber=%%H")
Set failNumber 2>NUL

I should try this one as well to see and will update the results soon. Thanks!
Yes it also works!

You could optionally modify the command to get the first pass number too:

Code: Select all

@Echo Off & SetLocal EnableExtensions DisableDelayedExpansion
Set "passNumber=" & For /F "Delims=" %%G In ('%SystemRoot%\System32\findstr.exe /IR
 /C:"window\.output\[\"stats\"\] = \[\[{.*\"[fp]a[is][ls]\":[0123456789][0123456789]*[,}]"
 "test.txt" 2^>NUL') Do (Set "matchedLine=%%G" & SetLocal EnableDelayedExpansion
	Set "matchedLine=!matchedLine:*"pass"=!" & For /F "Delims=:,}" %%H In (
		"!matchedLine:*"pass"=!") Do EndLocal & Set "passNumber=%%H")
Set passNumber 2>NUL
Pause & EndLocal & GoTo :EOF

A JScript hybrid would be pretty straightforward here. The number can be accessed directly as submatch of a regex pattern.

Code: Select all

@if (0)==(0) echo off &setlocal
for /f %%i in ('cscript //nologo //e:jscript "%~fs0" "test.txt"') do set "n=%%i"
echo %n%
pause

goto :eof @end
WScript.Echo(/"fail":(\d+)/.exec(new ActiveXObject('Scripting.FileSystemObject').OpenTextFile(WScript.Arguments(0)).ReadAll())[1]);

If you add a few simple manipulations, you can access all fields from all tests:

Code: Select all

@echo off
setlocal EnableDelayedExpansion

for /F "tokens=1* delims== " %%a in (test.txt) do set "line=%%b" & set "line=!line:~3,-4!" & set "line=!line:],[],[=,!"
set "i=0"
for %%N in (^"^
%Do NOT remove%
^") do (
   for /F "delims=" %%a in ("!line:},{=%%~N!") do (
      set /A i+=1
      echo/
      echo Test # !i!
      for %%b in (%%a) do for /F "tokens=1* delims=:" %%x in ("%%b") do echo %%~x=%%y
   )
)

Output:

Code: Select all
