获取定位标记HREF和VALUE

Question

I have a string that looks like this:

<a href="http://forum.tibia.com/forum/?action=board&boardid=476">Amera</a><br><font class="ff_info">This board is for general discussions related to the game world Amera.</font>

How can I ignore/remove everything after the </a> and then only get the url: http://forum.tibia.com/forum/?action=board&boardid=476 and the value Amera

So afterwards, I want 2 variables with their values, like:

string url = "http://forum.tibia.com/forum/?action=board&boardid=476";

and

string value = "Amera";

I tried this to get the value:

string value = System.Text.RegularExpressions.Regex.Replace(MYSTRING, "(<[a|A][^>]*>|)", "");

But it returns:

Amera</a><br><font class="ff_info">This board is for general discussions related to the game world Amera.</font>

Answer 1

For getting the URL, maybe try, this regex pattern: /href=\\"(.*)\\"/

...And to get the values between > Amera </a> use a pattern like: >(.+?)</a>

...although, this seems far from perfect...

Answer 2

If the a tag won't contain more attributes, you can use just this for the URL only:

\bhref="(.*?)"

And little more complex for URL and text:

<a\b[^>]*?\bhref="([^"]*?)"[^>]*?>(.*?)<\/a>

So in C# code (quotation marks need to be escaped!):

var html = "<a href=\"http://forum.tibia.com/forum/?action=board&boardid=476\">Amera</a><br><font class=\"ff_info\">This board is for general discussions related to the game world Amera.</font>";
var match = Regex.Match(html, "<a\\b[^>]*?\\bhref=\"([^\"]*?)\"[^>]*?>(.*?)<\\/a>", RegexOptions.IgnoreCase);
if (match.Success) {
    var url = match.Groups[1];
    var text = match.Groups[2]
}

Try this:

HtmlDocument dc = new HtmlAgilityPack.HtmlDocument();
        dc.LoadHtml("<a href='http://forum.tibia.com/forum/?action=board&boardid=476'>Amera</a><br><font class='ff_info'>This board is for general discussions related to the game world Amera.</font>");
        foreach (HtmlNode link in dc.DocumentNode.SelectNodes("a"))
        {
            string url = link.Attributes["href"].Value; // http://forum.tibia.com/forum/?action=board&boardid=476
            string value = link.InnerText; // Amera
        }
