To start your own data scraping project in Octoparse, you would have to create a task to crawl and extract data required.
Tasks in Octoparse means crawlers for scraping usually a website/couples of categories without limitation of pages/URLs crawling.
Octoparse simulates real browsing experience as it clicks, searches, paginates, etc. An Octoparse task you configure determines which URL to be open, how many pages to be retrieved, what data you need to collect…
This tutorial covers:
1) "Advanced Mode" Task/ "Wizard Mode" Task
By creating a task, click on "+ Task" button of "Advanced Mode" or "Wizard Mode".
We strongly recommend "Advanced Mode" to start your data extraction project. "Advanced Mode" offers more flexibility and allows you to easily handle complex web scraping cases such as keywords searching, login authentication, opening dropdowns…
"Wizard Mode" allows you to create very simple tasks with step-by-step guidance. Tasks created by "Wizard Mode" can be edited with "Advanced Mode".
There are 3 different kinds of wizards(extraction types) supported by Octoparse "Wizard Mode":
· List or Table
· List and Details
· Single Page
The most critical part of a task is the workflow for your specific data extraction requirements. Octoparse executes every step configured in the workflow to complete your data collection. In Octoparse 7.X version, we’ve added an on-and-off button for users to switch between "Select Mode" and "Workflow Mode".
For better task accuracy, we strongly suggest you turn on the “Workflow Mode” that gives you a better picture of what you are doing with your task, just in case you mess up the steps.
3) Task management
1. Task information editing
In Octoparse 7.X version, task name is automatically created as you save the URL entered.
