6 Ways to Extract Contents from Webpage Without Coding
1. Extract content from the dynamic web page
Web pages can be either static or dynamic. It’s often the case that the web content you want to extract would change throughout the day. It is often the case that the website will apply AJAX technique. Ajax allows the webpage to send and receive data from the background without interfering with the webpage display. In this case, you can check the AJAX option to allow Octoparse to extract content from dynamic web pages.

2. Extract content that is hidden from the web page
Have you ever wanted to get specific data from a website but the content would appear after you trigger a link or hover the mouse pointer over? For example, some contact information on craigslist.org will appear after you click the Reply button.
In fact, such hidden content could be found in the HTML source code of this web page. Octoparse can extract the text between the source code. It’s easy to use the “Click Item” command or a “Cursor over” command under the “Action Tip” Panel to achieve the action of extraction.
3. Extract content from the web page with infinite scrolling
You may also notice some messages are only uploaded once you scroll to the bottom of the web page like Twitter. This is because the websites apply infinite scroll. Infinite scroll usually accompanies AJAX or JavaScript to make the requests happen as you reach the end of the webpage. In this case, you can set the AJAX timeout, select the scrolling method and scrolling times to customize how you want the robot to extract the content.
4. Extract hyperlinks from the web page
A normal website will contain at least one hyperlink and if you want to extract all the links from one web page, you can use Octoparse to help you extract all URLs of the whole website.
