模式也匹配连字符

本文介绍了模式也匹配连字符的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一段这样的 Perl 代码(模式匹配)，

I have a piece of Perl code (pattern matching) like this,

$var = "<AT>this is an at command</AT>"; if ($var =~ /<AT>([\s\w]*)<\/AT>/i) { print "Matched in AT command\n"; print "$var\n\n"; }

它工作正常，如果标签之间的内容没有连字符.如果在像这样的标签之间存在的字符串之间插入连字符，则它不起作用...... <AT>这是一个 at-command</AT>.

It works fine, if the content inbetween tags are without an Hyphen. It is not working if a hyphen is inserted between the string present inbetween tags like this... <AT>this is an at-command</AT>.

即使还插入了连字符，任何人都可以修复此正则表达式以匹配吗??

Can any one fix this regex to match even if hyphen is also inserted ??

请帮帮我

使用 \S 而不是 \w.

Use \S instead of \w.

if ($var =~ /<AT>([\s\S]*)<\/AT>/i) {
