How to extract values in quote marks from HTML string?
c# html html-agility-pack javascript web-scraping
Question
The following line of code was taken from a website and is what I have:
<li class="player" data-id="168568" data-teamid="156" data-x="142.33" data-y="297.16040000000004" data-name="Corentin Tolisso" data-position="3">Corentin Tolisso<span class="shirt">24</span></li>
The name "Corentin Tolisso," the shirt size "24," and the data-x and data-y variables are the things I'm trying to extract.
I have so far been successful in making it function with values that are within>...<
HTML Agility Pack is used.
The numbers from data-x and data-y cannot be extracted, however, for some reason.
I cloned the HTML string into a new jsfiddle so that it would display precisely what my C# code is receiving, including the elements in between.>...<
.
How can I get data-x and data-values? y's
The following:String.IndexOf
works perfectly, but flexibility is lost. This is the backup plan I use.
Note 2: Although here and here gave me some insight, I still struggled to adapt it to C#.

one method would be to use(["'])(?:(?=(\\?))\2.)*?\1

<form name="input" action="handle_email.php" method="post">
Email: <input type="text" name="email" />
<input type="submit" value="Newsletter" />
</form>
<a id="regLink" href="http://mywebsite.com/register?user_email=">Register</a>
$('input[name="email"]').change(function(){
alert($('#regLink').attr('href')+$('input[name="email"]').val());
});
