title: C# Search in html, get links, follow them and grab some info from each page
body: <p>I do NOT ask for the complete solution. It would be nice to hear any advice.</p>
  
  <p>I'm sorry if that kind of question has already been asked.
  Well, I have an html file containing a lot of lines (saved on my PC).
  Example: </p>
  
  <pre><code>&lt;/li&gt;&lt;li class="vertical" style="width: 20%;"&gt;
  &lt;div class="item-box vertical flex-auto"&gt;
  &lt;div class="image-box vertical center flex-auto"&gt;&lt;a target="_blank" href="https://www.aliexpress.com/item/-/32794448855.html?scm=1007.14110.78103.0&amp;amp;pvid=98337ce3-4886-4639-99f3-5dcaf226a0af" class="fade-in"&gt;&lt;img src="./Электроника – Распродажа «Нам 7 лет» – AliExpress.com_files/HTB1fDZgPFXXXXXiapXXq6xXFXXXQ.jpg_350x350.jpg" alt="KingDian Новый Универсальный 2.5 &amp;quot;до 3.5&amp;quot; SSD HDD Окружающей Среды Пластмасс Адаптер Кронштейн Держатель Жесткого Диска для Настольных ПК"&gt; &lt;/a&gt;&lt;/div&gt;
  </code></pre>
  
  <p>This code contains links like that:</p>
  
  <pre><code>https://www.aliexpress.com/item/-/32794448855.html?scm=1007.14110.78103.0&amp;amp;pvid=98337ce3-4886-4639-99f3-5dcaf226a0af
  </code></pre>
  
  <p>I need to grab all the links of the kind. Export them to any type of a document. Follow them. And on each page I need to find the line containing the price (Id "j-sku-discount-price" on every page).</p>
  
  <pre><code>&lt;span id="j-sku-discount-price" class="p-price" itemprop="price" style="color: rgb(247, 43, 76);"&gt;4&amp;nbsp;467,04&lt;/span&gt;
  </code></pre>
  
  <p>This is the price found in html code:</p>
  
  <pre><code>4&amp;nbsp;467,04
  </code></pre>
  
  <p>And export price so it would be close to its link.</p>
  
  <p>E.g.:</p>
  
  <pre><code>https://www.aliexpress.com/item/-/32794448855.html?scm=1007.14110.78103.0&amp;amp;pvid=98337ce3-4886-4639-99f3-5dcaf226a0af 4&amp;nbsp;467,04
  </code></pre>
  
  <p>It would be perfect if it could be stored in Excel.</p>
  
  <p>Thank you for your ideas.</p>
