使用正则表达式将路径与路径分开

Question

我在此路径中有一个文件

D:\ebook\comic\Author,_Title_of_Book_(http://google.com).cbz

我需要使用正则表达式分隔字符串并获取作者，标题和URL。 文本输出应为

Author
Title_of_Book
http://google.com

到目前为止我已经

([^\\]+)\.[^\\]+$

这将只给我文件。

UPDATE @RoYoMi发布了一个非常优秀的答案，但是由于我已经完成了这项工作，所以你走了。

由于您只在此处标记了正则表达式，因此我不知道您需要使用哪种语言才能使用。我为此示例进行了JSFiddle测试。这是代码。

<p>
  <input type="text" id="val" value="D:\ebook\comic\AuthorLastName_FirstName,Title_of_Book_(http://google.com).cbz" style="width:100%;" />
</p>
<div id="name"></div>
<div id="title"></div>
<div id="url"></div>
<script>
    var val = document.getElementById("val").value;

    var name = /\w+(?=[,])/.exec(val).toString().replace(/[_]/g, " ");
    var title = /\w+(?=[(])/.exec(val).toString().replace(/[_]/g, " ");

    var url = /((http)(s?)[:](\/\/))(.*?)(?=[)])/i.exec(val)[0].toString();
    //Better suited with a look behind like this:
    //var url = /(?<=[(])(.*?)(?=[)])/.exec(val).toString();
    //But JS doesn't support look behinds.

    document.getElementById("name").innerHTML = name;
    document.getElementById("title").innerHTML = title;
    document.getElementById("url").innerHTML = url;
</script>
