从 html 链接中提取标题 [英] Extract Title from html link

问题描述

我有以下 HTML 字符串:

I have the following HTML string:

<a href="/tothepage" title="the page">The Link</a>.  

如何轻松地从 HTML 片段中提取标题?首选正则表达式或其他 VB.NET 解决方案，但 C# 也可以.

How can I extract title from the HTML snippet with ease? Either a regex or other VB.NET solution is preferred but C# is ok.

我想要页面"而不是链接文本:我想要标题属性的值.

I want 'the page' not the link text: I want the value of the title attribute.

我已经安装了 HTMLAgilityPack，如果这样做很容易的话.

I have HTMLAgilityPack installed if it's easy to do it with that.

推荐答案

使用正则表达式，组将包含它([^"]*):

With a regular expression, the group will contain it ([^"]*):

title="([^"]*)"

C#

using System.Text.RegularExpressions;
static void Main(string[] args)
    {
        string originalString = "<a href=\" / tothepage\" title=\"the page\">The Link</a>.";
        Regex rgx = new Regex("title=\"([^\"]*)\"", RegexOptions.IgnoreCase);
        Match match = rgx.Matches(originalString)[0];
        Console.WriteLine(match.Groups[1]);
        Console.ReadLine();
    }
