Question

我正在尝试从游戏中解析此telnet输出。我尝试使用正则表达式，但它不会捕获任何内容，并始终返回null。我从搜索中尝试了几个不同的示例，但是没有用。下面是我的字符串，我想在和之间捕获，稍后我想捕获所有 <项目... > 在标签中。我已将 str 的输出发送到控制台，并且所有输出均按预期显示。这是我当前正在尝试的正则表达式，它返回null。

    var result = str.match( /<motd>(.|\n|\r\n)*?<\/motd>/g );
    console.log(result);

和str：

    <motd>

Answer 1

使用DOM解析器。与您的问题最接近的是JQuery DOM解析器。

var myOut = $.parseXML(str);   

var items = $(myOut).find('item');

Answer 2

尝试正则表达式：

/<motd>[^<>]*?<\/motd>/igm

这里：

i：要忽略大小写
g：用于全局搜索
m：用于多行匹配

用正则表达式解析带标记的输出的Java脚本
