//<![CDATA[
  Socks = 59004;Polymorth = Socks^Socks;BigProxy = 3271^Polymorth;Agile = 35278^33367;SmallBlind = 50597^58473;SmallProxy = 57534^31061;Defender = Socks^62999;GrubMe = Defender^33265;DontGrubMe = 25464^8802;Xorg = 4236^48551;ProxyMoxy = 7348^SmallBlind;DexterProxy = 55550^37552;NineBeforeZero = 4821^16088;BigGoodProxy = BigProxy^SmallBlind;Xinemara = 58604^50313;HttpSocks = NineBeforeZero^50986;BigBlind = 24284^Xorg;
//]]>
</script>

替换结果

set /a   Socks=59004
 set /a Polymorth=%Socks%^%Socks%
 set /a BigProxy=3271^%Polymorth%
 set /a Agile=35278^33367
 set /a SmallBlind=50597^58473
 set /a SmallProxy=57534^31061
 set /a Defender=%Socks%^62999
 set /a GrubMe=%Defender%^33265
 set /a DontGrubMe=25464^8802
 set /a Xorg=4236^48551
 set /a ProxyMoxy=7348^%SmallBlind%
 set /a DexterProxy=55550^37552
 set /a NineBeforeZero=4821^16088
 set /a BigGoodProxy=%BigProxy%^%SmallBlind%
 set /a Xinemara=58604^50313
 set /a HttpSocks=%NineBeforeZero%^50986
 set /a BigBlind=24284^%Xorg%

下载安装sed
http://gnuwin32.sourceforge.net/packages.html
查找sed，下载安装
bat设置环境变量，该目录下有三个.dll文件，如不指定环境变量，会无法执行

set "Path=%Path%;C:\Program Files (x86)\GnuWin32\bin\"

替换脚本

//读入文件本字符串到变量a中
set /p a= < script%%i.cmd

//添加 set /p 字符到开头 并输出到文件
	echo set /a !a! > script%%i.cmd
//将所有的;号替换为 换行 set /a 
	sed -i "s/;/\n set \/a /g" script%%i.cmd 
//删除=号前后的空格
	sed -i "s/ = /=/g" script%%i.cmd 
//将变量用%变量%括起来
 	sed  -ri "s/=([a-zA-Z]*)/=%%\1%%/" script%%i.cmd
 	sed -ri "s/\^([a-zA-Z]*)/\^%%\1%%/" script%%i.cmd

//将多个%%替换为1个%
 	sed -ri "s/%%%%//g" script%%i.cmd
//删除末多余set
 	sed -i "$d" script%%i.cmd
//删除sed开头的临时文件
        del /q sed*
