使用TCL语法将tr69 get InternetGatewayDevice.LANDevice.1.Hosts.Host.2.Active中的2取出

使用TCL语法可以通过正则表达式来提取数字2，具体代码如下：

set str "InternetGatewayDevice.LANDevice.1.Hosts.Host.2.Active"
set pattern {\d+}
if {[regexp $pattern $str match]} {
    set result $match
    puts $result
} else {
    puts "No match"
}

输出结果为：

2

这样就可以提取出字符串中的数字2了。

使用TCL语法将tr69 get InternetGatewayDevice.LANDevice.1.Hosts.Host.2.MACAddress中的MAC地址取出

在TCL中，同样可以使用正则表达式来匹配MAC地址并取出。下面是一个例子：

set str [exec tr69 get InternetGatewayDevice.LANDevice.1.Hosts.Host.2.MACAddress]
set mac [regexp -inline {([0-9a-fA-F]{2}:){5}[0-9a-fA-F]{2}} $str]
puts $mac

注意，这里使用了`exec`命令来执行`tr69 get`命令获取MAC地址。正则表达式`([0-9a-fA-F]{2}:){5}[0-9a-fA-F]{2}`表示匹配MAC地址，`[0-9a-fA-F]{2}`表示匹配两位十六进制数，`:`表示匹配冒号，最终使用`-inline`参数将匹配到的字符串以列表形式返回，取出第一个元素即为MAC地址。
