我需要閱讀敏捷包一個HTML文件，該文件包含

<span class=\"price\"> 
 
<span itemprop=\"offers\" itemscope itemtype=\"http://schema.org/Offer\" class='current'> 
 
<span itemprop="price">8,160,000 ریال </span> </span> 
 
<span class=\"price-last-update\" original-title=\"تاریخ به روز رسانی\">1396/03/23 </span> </span>

上面的代碼是重複的次數和 我想要的HTML的一部分選擇此部分

<span itemprop="price">8,160,000 ریال

與此代碼：

string price = node.SelectSingleNode("/span/span/span[@class='price'").InnerText; 

，但它不工作，感謝您的幫助

var txt = @" 
<span class='price'> 
<span itemprop='offers' itemscope itemtype='http://schema.org/Offer' class='current'> 
     <span itemprop='price'>8,160,000 ریال </span> 
    </span> 
    <span class='price-last-update' original-title='تاریخ به روز رسانی'>1396/03/23 </span> 
</span> 
"; 

var doc = new HtmlAgilityPack.HtmlDocument(); 
doc.LoadHtml(txt); 

Console.WriteLine(doc.DocumentNode.SelectSingleNode("/span[@class='price']").InnerText); 
// 8,160,000 ریال 1396/03/23 
Console.WriteLine(doc.DocumentNode.SelectSingleNode("//span[@class='price']/span").InnerText); 
// 8,160,000 ریال
