We recently came across a automated web crawler called Octoparse. This can help us find what we are looking for in a matter of seconds but the data is not structured and hence can’t be used for analysis. They go from link to link and bring data about those webpages back to Google’s servers. Crawlers, like Google’s, look at webpages and follow links on those pages. There are various ways to acquire data from websites of your preference. We used Octoparse to scrape data from a list of URLs, without any coding at all.ĭata is valuable and it’s not always easy to get the correct data from the web sources because all websites have different templates and designs. Note: Please remember to click "Save" after any of setting.Did you know you can scrape data from webpages without writing a single line of code? In this post, we will talk about a tool called Octoparse. Setting up waiting time would slow down the extraction process so as to lower the risk of IP being blocked by a website, which is sensitive to frequent visits. When the website blocks IP that visits it too frequently Some waiting time before extracting action would help load the data completely and extract them successfully.ģ. Octoparse may report extraction failure in such a case as it will start extracting right after the page opens. Sometimes the pages are designed not to show the data directly but load the data with JavaScript after the page opens. When Octoparse extracts data before the data shows on the page Setting up waiting time before for action helps the extraction process go well in such a situation.Ģ. As a result, it extracts no data and finishes the extraction or extracts duplicates before the next page comes out. In some cases, a page opens slowly but Octoparse executes extracting data as usual. When Octoparse extracts data or executes the next action when a page opens slowly or does not load completely When do I need to set up Wait Before Execution?ġ. "Wait Before Execution" is a function that allows users to set up a waiting before Octoparse executes some action.Īll the actions in Octoparse except "Go To The Web Page" have that option in Advanced Options. The updated version of this tutorial (based on the latest webpage) is available now.
