HTML for Webscraping

 We covered the basics of HTML for web scraping. Here's a summary of what we discussed:

  1. Understanding HTML Structure:

    • HTML documents consist of elements enclosed in angle brackets called tags.
    • The <html> element is the root element of an HTML page.
    • The <head> element contains meta information about the HTML page.
    • The <body> element contains the content displayed on the web page.
    • Tags like <h3> indicate headings, and <p> indicate paragraphs.
  2. Composition of HTML Tags:

    • Tags have an opening (<tag>) and a closing (</tag>) tag.
    • Tags may contain attributes, consisting of a name and value, such as <a href="url">.
  3. HTML Trees:

    • HTML documents can be represented as trees, with nested tags as branches.
    • Tags can have children, siblings, and parents, forming a hierarchical structure.
  4. HTML Tables:

    • Tables in HTML are defined with the <table> tag.
    • Each table row is defined with the <tr> tag, and cells are defined with <td> tags.
    • Tables may also have a header row defined with the <th> tag.

After understanding these concepts, we can extract data from a webpage using web scraping techniques. This involves parsing the HTML structure of the webpage to locate and extract specific data elements, such as player names and salaries from a sports webpage.
