Batch script get html site and parse content (without wget, curl or other external app)

I need to work with windows cmd functionality only. I need two vars/strings from a website to use in the batchscript for validate actions with it. To not make it too simple this website needs authentification in addition.

I found this somewhere:

@set @x=0 /*
:: ChkHTTP.cmd
@echo off
setlocal
set "URL=http://www.google.com"
cscript /nologo /e:jscript "%~f0" %URL% | find "200" > nul
if %ErrorLevel% EQU 0 (
echo Web server ok % Put your code here %
) else (
echo Web server error reported
)
goto :EOF

JScript */
var x=new ActiveXObject("Microsoft.XMLHTTP");
x.open("GET",WSH.Arguments(0));x.send();
while (x.ReadyState!=4) {WSH.Sleep(50)};
WSH.Echo(x.status)

But I'm not sure if it's possible to get the site content this way too instead of status answer and the more I don't know how to implement website authentification to this.

The above code does not work correctly as it will always produce error because of the pipe, but this seemed nearer to my needs of parsing the content I hoped.

I've only ever used wget to fetch web content from a Windows batch script. Using an XHR via JScript was a fantastic idea!

But the script you're trying to plunder appears to be intended for checking whether a web server is responding, not for fetching content.

With some modifications, you can use it to fetch a web page and do whatever processing you need.

@if (@a==@b) @end /*

:: fetch.bat <url>
:: fetch a web page

@echo off
setlocal
if "%~1"=="" goto usage
echo "%~1" | findstr /i "https*://" >NUL || goto usage

set "URL=%~1"
for /f "delims=" %%I in ('cscript /nologo /e:jscript "%~f0" "%URL%"') do (
    rem process the HTML line-by-line
    echo(%%I
)
goto :EOF

:usage
echo Usage: %~nx0 URL
echo     for example: %~nx0 http://www.google.com/
echo;
echo The URL must be fully qualified, including the http:// or https://
goto :EOF

JScript */
var x=new ActiveXObject("Microsoft.XMLHTTP");
x.open("GET",WSH.Arguments(0),true);
x.setRequestHeader('User-Agent','XMLHTTP/1.0');
x.send('');
while (x.readyState!=4) {WSH.Sleep(50)};
WSH.Echo(x.responseText);
