What is an XPath?

Introduction #

Understanding what an XPath is, is not just crucial for using our tool; it’s a key to unlocking a world of data from the web. So let’s get stuck in.

XPath: The “Address” to Web Elements #

Think of a website as a giant skyscraper. Each skyscraper has different floors, rooms, and even items within those rooms. In the world of web development, these floors, rooms, and items are what we call “elements.”

An element could be anything — a block of text, an image, a button, or even a blank space. XPath, or XML Path Language, acts as the “address” that helps you locate these specific elements within the intricate structure of a web page. Just like you’d give someone your home address to find your exact location, you can give our web scraper the XPath to pinpoint the exact web element you’re interested in scraping data from. The web scraper can then extract the content within the element for you to use.

A Simple XPath Example #

Understanding XPath syntax can be helpful, but isn’t strictly necessary thanks to handy tools. You may want to skip to how to find an XPath.

With that being said, let’s consider a simple piece of HTML code that makes up a part of a web page:

    <title>My Web Page</title>
      <p>Hello, world!</p>
      <p>Welcome to my website.</p>

In this example, the XPath to target the first paragraph (<p>Hello, world!</p>) would be something like /html/body/div/p[1]. This XPath address starts from the root (html) and navigates through the body, the division (div), and finally selects the first paragraph element.

Providing this XPath to a web scraping tool like InfinityXML would allow the “Hello, world!” text to be extracted. If the text within that element were to change, then running the scraper again would return that new, updated text.

How to Find an XPath #

Web Browser Inspect Tool #

  1. Open your web browser and go to the page you want to scrape data from.
  2. Right-click on the element you want to scrape and choose ‘Inspect Element’ or simply ‘Inspect’.
  3. In the Developer Tools pane that appears, the element you selected should be highlighted.
  4. Right-click on that highlighted element within the Developer Tools pane, and you should see an option to ‘Copy’ and then ‘Copy XPath’.

Congratulations! You’ve just found an XPath. You can use it to extract text within the element it points to using a web scraper like InfinityXML.

SelectorsHub is an excellent Chrome extension that simplifies the process of finding XPaths, even for complex elements.
