Question

在tcl语言中，我得到一些输出：

xCommand Experimental Conference ParticipantList Search CallId: 231

OK
*r ParticipantListSearchResult Participant 1 Index: 0
*r ParticipantListSearchResult Participant 1 ParticipantId: "sip:9503806@10.89.70.92;ci=23543253"
*r ParticipantListSearchResult Participant 1 Uri: "sip:9503806@10.89.70.92;ci=23543253"
*r ParticipantListSearchResult Participant 1 DisplayName: "9503806"
*r ParticipantListSearchResult Participant 1 Status: "connected"
*r ParticipantListSearchResult Participant 1 AudioMute: Off
*r ParticipantListSearchResult Participant 2 Index: 1
*r ParticipantListSearchResult Participant 2 ParticipantId: "sip:9503808@10.89.70.92;ci=23543256"
*r ParticipantListSearchResult Participant 2 Uri: "sip:9503808@10.89.70.92;ci=23543256"
*r ParticipantListSearchResult Participant 2 DisplayName: "9503808"
*r ParticipantListSearchResult Participant 2 Status: "connected"
*r ParticipantListSearchResult Participant 2 AudioMute: Off
*r ParticipantListSearchResult Participant 3 Index: 2
*r ParticipantListSearchResult Participant 3 ParticipantId: "sip:9503807@10.89.70.92;ci=23543254"
*r ParticipantListSearchResult Participant 3 Uri: "sip:9503807@10.89.70.92;ci=23543254"
*r ParticipantListSearchResult Participant 3 DisplayName: "9503807"
*r ParticipantListSearchResult Participant 3 Status: "connected"
*r ParticipantListSearchResult Participant 3 AudioMute: Off
** end

我需要：

DisplayName: "9503806"
DisplayName: "9503808"
DisplayName: "9503807"

作为我的输出，如何为它编写正则表达式？

Answer 1

您只需要1张外卡即可匹配不同的数字和正确的功能。让我们说你的文字在变量$output中，然后执行：

set results [regexp -all -inline -- {DisplayName: "[0-9]+"} $output]

$results是一个列表。因此，如果您想将它们打印在另一个之下，您可以这样做：

puts [join $results \n]

DisplayName: "[0-9]*"

怎么样？

使用正则表达式从字符串中获取特定值
