i am trying to parse the output of another function which is output line by line. to understand the function, it returns several lines of parameter and numbers like "`top=123456789`" or "`low=123456789`" (without the quotations) - 

i try to parse the lines now with

```
for /F "delims=" %%a in ('%%I ^| findstr top') do set updir=%%1
set "updir=%1:~4%" 
echo. %updir%

```

i am trying to get the pure numbers by trimming the known keywords like top, which would need then to be set to a var to return (`%~1% ???`) to a calling function back (other batch file). 

could anyone help me with this please? shure it would be better to trim right from "=".

UPDATE:

this is the code returning the lines from the script i linked. i tried several ways to parse the return but i seem to be blind or too stupid to see, all is going weird.

```
for /f "delims=" %%I in ('cscript /nologo /e:jscript "%~f0" "%URL%"') do (
rem process the HTML line-by-line

org echo(%%I

try1 (echo %%I|findstr top

try2 for /F "delims=" %%a in ('%%I ^| findstr top') do set updir=%%a
try2 echo. %updir%

try3 for /F "delims=" %%a in ('%%I') do findstr top
try3 echo. %2%

)

```

didn't work either

```
for /F "tokens=1,2delims==" %%a in ('%%I') do if %1 == top set updir=%%b
echo %updir%

```

i tried both delim version beneath (too the tokens/delims version) but i don't get it right.

UPDATE SOLUTION:

for the ones reading the question here some additional comment:

```
rem trim whitespace from beginning and end of line
for /f "tokens=*" %%x in ("%%~I") do set "line=%%x"

rem test that trimmed line matches "variable=number"

```

`to find a single item like e.g. "top" you have to add "to" or adjust whole first token`  

 echo !line! | findstr /i "^`to`[a-z]*=[0-9]*" >NUL && (

```
rem test was successful.  Scrape number.
for /f "tokens=2 delims==" %%x in ("%%I") do set "value=%%x"
echo !value!
)

```
