Question

您好我正在处理一个允许我从输入中解析信息的小脚本。这是有效的，但我知道有更好的方法来做到这一点。拜托，我正在努力学习[自学成才]所以撕毁我。输入内容如下：

C7-0-4-U1   36.5 mHz    IN7-0-4-0   567 mHz 00:15:d0:e3:b0:41   online(pt)  10.106.156.129  42.0    -0.5    35.1    -3.0    38.7    0.0E+000    0.0E+000    9   0    12:20:32 AM    rZ5 1

Answer 1

这是我的解决方案：

# read entire file
set fid [open file.txt r]
set txt [read $fid]
close $fid

# split into lines
set lines0 [split $txt \n]

# take only non-empty lines
set lines {}
foreach line $lines0 {
    if {[string trim $line] ne ""} {
        lappend lines $line
    }
}

# extract the required data from each line
foreach line $lines {
    set data [regexp -inline {(\w{2}:\w{2}:\w{2}:\w{2}:\w{2}:\w{2})\s+\S+\s+ (\d+.\d+.\d+.\d+)} $line]
    foreach {dummy x y} $data {
        puts "$x\t$y"
    }
}

我使用正则表达式搜索由冒号分隔的六个2-chars单词的模式，然后是一个空格后跟一个单词后跟一个空格（\ s + \ S + \ s +）然后是ip的模式地址。

regexp返回一个trios列表（它是flat，而不是列表列表），其中每个trio由整个匹配组成，然后是第一个parnthesis匹配，然后是scond one。因此虚拟变量。

或者，您可以使用正则表达式，因为每行具有相同数量的单词。因为在tcl中你可以将字符串视为alist，其项目由空格分隔，你可以更简单地通过以下方式提取数据：

foreach line $lines {
    set x [lindex $line 6]
    set y [lindex $line 8]
    puts "$x\t$y"
}

Answer 2

好吧，假设我们从txt文件加载它，那就是我要做的：

set input [open "file.txt" r]
set output [open "output.txt" w]
set count 1

while {[gets $input line] != -1} {
    if {$line == ""} {continue} #Skip empty lines
    regexp -all {(\w{2}:\w{2}:\w{2}:\w{2}:\w{2}:\w{2})} $line - MacAddress #trap the mac address and store into $MacAddress
    regexp -all {(\d+\.\d+\.\d+\.\d+)} $line - IpAddress #trap the IP address and store into $IpAddress
    puts $output "Customer $count: $MacAddress $IpAddress"
    incr count
}

close $input
close $output

如果你能说哪个顾客是哪个^^，我认为这可能很奇特。如果您不需要额外的功能，可以删除零件'客户$ count'以及任何涉及'$ count'的行。

或者如果输入数据是表格形式（意味着您需要的信息在同一列中，我会选择：

set input [open "file.txt" r]
set output [open "output.txt" w]
set count 1

while {[gets $input line] != -1} {
    if {$line == ""} {continue} #Skip empty lines
    regsub -all { +} $line " " newline #trims excess spaces
    set MacAddress [lindex [split $line " "] 6]
    set MIpAddress [lindex [split $line " "] 8]
    puts $output "Customer $count: $MacAddress $IpAddress"
    incr count
}

close $input
close $output
