既然是json文件，那就按json处理呢？不用正则应该可以，如有样本可以试一下

terse

提取含browser\features\ 关键词的路径

@if(0)==(0) @echo off
set "file=extensions.json"
set "s=\browser\features\" 
cscript.exe -NoLogo -E:JScript %0  "%file%" "%s%"
PAUSE & exit/b
rem 保存为ANSI文件
 
@end
 
function adoLoadText(filename, charset) {
    stream = new ActiveXObject("ADODB.Stream");
    stream.type = 2;
    stream.charset = charset;
    stream.open();
    stream.loadFromFile(filename);
    text = stream.readText(-1);
    stream.close();
    return(text);
}
 
var file = WSH.Arguments.Item(0);
var jsontext =adoLoadText(file, "UTF-8");
var obj = new Function("return" + unescape(jsontext))();
var re = new RegExp(WSH.Arguments.Item(1).replace(/[.*+?^${}()|[\]\\]/g, "\\$&"));
for (var k  in obj) {var arr = obj[k] }
for (var i=0, len = arr.length;  i<len;i++) {
      var path=arr[i]["path"]
      if (re.test(path))  {WSH.Echo(path)}
}COPY

先ECHO 看这样替换成功不 （没写入文件）

@if(0)==(0) @echo off
set "file=extensions.json"
set "oid=%cd%"
set "s=(?=\Profiles\extensions\|\browser\features\)" 
cscript.exe -NoLogo -E:JScript %0  "%file%" "%s%" "%oid%"
PAUSE & exit/b
rem 保存为ANSI文件
 
@end
 
function adoLoadText(filename, charset) {
    stream = new ActiveXObject("ADODB.Stream");
    stream.type = 2;
    stream.charset = charset;
    stream.open();
    stream.loadFromFile(filename);
    text = stream.readText(-1);
    stream.close();
    return(text);
}
var s = WSH.Arguments.Item(1);
var p = WSH.Arguments.Item(2);
var file = WSH.Arguments.Item(0);
var jsontext =adoLoadText(file, "UTF-8");
var obj = new Function("return" + unescape(jsontext))();
var re = new RegExp(s.replace(/\\/g, "\\$&"));
var reg =new RegExp( '('+ '.+?' + ')'+ s.replace(/\\/g, "\\$&"));
for (var k  in obj) {var arr = obj[k] }
for (var i=0, len = arr.length;  i<len;i++) {
      var path=arr[i]["path"];
      if (re.test(path))
      {
           WSH.Echo( path.replace( reg, function($a,$b) { return( p ) } ) );
      }

直接正则替换效率提高的  练手一下
PS

<# :
@echo off

$(gc extensions.json -Raw -Encoding UTF8) -replace $pat , $oid | sc 'extensions.json' -Encoding UTF8COPY

JS代码长，效率不低

set "file=extensions.json"
set "ph=%~dp0"
cscript.exe -NoLogo -E:JScript %0  "%file%" "%ph:~,-1%"

    stream.charset = charset;
    stream.open();
    stream.loadFromFile(filename);
    text = stream.readText(-1);
    stream.close();
    return(text);
}
 
function adoSaveText(filename, text) {
  var stream;
  stream = new ActiveXObject("ADODB.Stream");
  stream.type = 2;
  stream.charset ='utf-8';
  stream.open();
  stream.writeText(text);
  stream.saveToFile(filename, 2);
  stream.close();

我这边测试的是你发的extensions.json文件，都通过测试，系统win10
会不会文件编码问题
