提取两个字符PowerShell之间的所有字符串(extract all the strings between two characters powershell)

 以下是两个字符。 1. {{2.}}我试图在以下文件中找到这些字符之间的所有字符串。 
 
    <add key="CSDFG_SqlServerFailOverInterval" value="{{environment}}"/>
    <add key="CSDFG_JobResetInterval" value="600000"/>
    <add key="FileTypeFilter" value="{{filetype}}"/>
 
 我正在使用下面的PowerShell命令， 
 
$x = C:\app.config
$s = Get-Content $x
$prog = [regex]::match($s,'{{([^/)]+)}}').Groups[1].Value
write-host $prog
 
 而我的输出只是一个字符串。 它并没有拉动所有的琴弦。 有人可以建议我如何得到所有的字符串。 提前致谢。 

Following are the two characters. 1. {{ 2. }} I'm trying to find all the strings between these characters in the following file.
 
    <add key="CSDFG_SqlServerFailOverInterval" value="{{environment}}"/>
    <add key="CSDFG_JobResetInterval" value="600000"/>
    <add key="FileTypeFilter" value="{{filetype}}"/>
 
and I'm using following powershell commands,
 
$x = C:\app.config
$s = Get-Content $x
$prog = [regex]::match($s,'{{([^/)]+)}}').Groups[1].Value
write-host $prog
 
and my output is just one string. it is not pulling all the strings. Can someone please suggest me how to get the all the strings. Thanks in advance.
