使用C＃在HTML中解析完整字符串

Question

I have the following two examples of html-

<a href="http://foo.com">User</a>: <a style="color:#333" href="http://foo.com/word"></a> blue elephant  &middot;

<a href="http://foo.com">User</a>: <a style="color:#333" href="http://foo.com/word">@<b>word</b></a> blue elephant  &middot;

I am trying to parse this using C# to put into a csv file and it is working to an extent however, when the html contains the '@' symbol in it, it will either leave the csv cell blank or not include the word with '@' before it. The main part I am trying to get is @word blue elephant however this is bringing back a blank cell, whereas the first html example brings back blue elephant as desired.

I am using the following technique to do this-

string[] comm = System.Text.RegularExpressions.Regex.Split(content[1], "<a");

How can I alter this to work for the second html example?
