一个多行输出:InternetGatewayDevice.LANDevice.1.Hosts.Host.2.Active 1
时间: 2024-03-09 12:47:33 浏览: 15
如果你想要在TCL中提取这个多行输出中的数字(即 `1`),你可以使用以下代码:
```tcl
set output "InternetGatewayDevice.LANDevice.1.Hosts.Host.2.Active 1"
regexp {Active (\d+)} $output match number
puts $number
```
解释一下这段代码:
- `{Active (\d+)}` 是一个正则表达式,用于匹配 `Active` 后面的数字。`\d+` 表示匹配一个或多个数字。
- `$output` 是要匹配的多行输出。
- `match` 是一个变量,用于存储匹配结果。
- `number` 是一个变量,用于存储匹配结果中的数字部分。
这段代码最终输出的结果是 `1`,即匹配到的数字。
希望这个回答能够帮助到你!

如何使用TCL语法将InternetGatewayDevice.LANDevice.1.Hosts.Host.2.Active 1中的2匹配取出来
可以使用Tcl中的`regexp`命令来实现正则表达式匹配,并使用匹配到的子字符串。以下是一个示例代码:
```tcl
set string "InternetGatewayDevice.LANDevice.1.Hosts.Host.2.Active 1"
set pattern {InternetGatewayDevice.LANDevice.1.Hosts.Host.(\d+).Active 1}
if {[regexp $pattern $string match number]} {
puts $number ;# 输出 2
}
```
这里的正则表达式`InternetGatewayDevice.LANDevice.1.Hosts.Host.(\d+).Active 1`与Python中的是类似的,其中`\d+`表示匹配数字。`regexp`命令用于在字符串中搜索匹配项,并将匹配到的子字符串保存在`match`变量中。最后,使用`puts`命令打印出匹配到的数字。
