HTMLAgilityPack 获取 class innerText

Question

我正在尝试获取 class 的 innerText。这是我的代码：

using (HttpClient clientduplicate = new HttpClient())
{
    clientduplicate.DefaultRequestHeaders.Add("User-Agent",
        "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident / 6.0)");

    using (HttpResponseMessage responseduplicate = await clientduplicate.GetAsync(@"https://www.investing.com/news/stock-market-news/warren-buffett:-i-bought--billion-of-stock-after-trump-won-456954")
    using (HttpContent contentduplicate = responseduplicate.Content)
    {
        try
        {
            string resultduplicate = await contentduplicate.ReadAsStringAsync();

            var websiteduplicate = new HtmlDocument();
            websiteduplicate.LoadHtml(resultduplicate);

            var titlesduplicate = websiteduplicate.DocumentNode.Descendants("div").FirstOrDefault(o => o.GetAttributeValue("class", "") == "arial_14 clear WYSIWYG newsPage");
            var match = Regex.Match(titlesduplicate.InnerText, @"(.*?)<!--", RegexOptions.Singleline).Groups[1].Value;

            Debug.WriteLine(match.TrimStart());
        }
        catch(Exception ex1)
        {
            var dialog2 = new MessageDialog(ex1.Message);
            await dialog2.ShowAsync();
        }
    }
}

现在的问题是，这也会 return 图片上的文字。我可以找到解决方法，但我想知道是否还有其他方法。东西 simpler/faster.

此外，当我在其他 articles/URLs 上使用它时，还有其他小错误。

有很多方法可以做到这一点。一种方法是在获取 innerText 之前删除轮播 div： doc.DocumentNode.Descendants("div").FirstOrDefault(_ => _.Id.Equals("imgCarousel"))?.Remove();
