To make data extraction easier, Octoparse features filling out forms, entering a search term into the text box, etc.

The software simulates human actions to interact with web pages.

Octoparse is a Windows application and is designed to harvest data from both static and dynamic websites. Below is the list of items that we are going to cover in this post We managed to do that with Octoparse without any coding at all. We’ll extract meta-data about the posts published on this blog. In this post, we will talk about Octoparse and different extraction rules which we configured to scrape our blog. Octoparse has many built-in tools and APIs to crawl and re-format the extracted data using a user-friendly point & click UI. Octoparse can scrape any data visible on a webpage.

Using Octoparse, you can develop extraction patterns and define extraction rules which would tell Octoparse which website is to be opened, how to locate the data you plan to scrape and what kind of data you want etc. 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. With this X Path, the loop would end when Octoparse comes to the last page.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. On the last page, no "Next Page" button is found just like how we want it. On the first page, yes the 'Next Page' button is correctly located. Now, let's do a quick check on the last page with the modified XPath. So we can utilize this 'difference' to modify the X Path to gspr next'] to locate all the 'Next Page' button but the one on the very last page (learn more about X Path here). On the last page the class is " gspr next-d": On the first page the class is "gspr next": If we use this auto-generated X Path, the loop would not end and Octoparse would extract data from the last page repeatedly leading to endless scraping and duplicates.īut if we look at the codes of the buttons on the two pages, we can easily find the difference: the "class" attribute of "a" tag is different. On the page below, the Next Page button is still visible on the last page and can be located with the X Path auto-generated by Firebug. Here is an example to elaborate more about it ( Example URL). So the trick is really to look for anything (most likely any icons for "Next") that persist until the very last page needed then write an XPath for it. For example, a cycle page loop should end itself when the X Path of the 'Next' button can no longer be located on the current page. The loop should end itself when such an element can no longer be located from the current page. The logic behind this is really to use an element from the page as an indicator of whether there's more to loop for. But in case if you have no idea of when to end the loop, you will need to modify the X Path of the loop manually. Setting "End loop" is easy and quick if you already know how many times to execute the loop (for example you may already know how many times you need to click the next page button). The loop will end after it's been repeated for the designed number of times. To use this option, just click on the loop item, under Advanced Options, click open "End loop when", tick "Execution time reach", pick a number then click "Save".

This option is perfect for anyone that knows exactly how many times they want to repeat the loop, a good example will be if an user wants to paginate 5 times only when there are more than 5 pages really. "End Loop" is an advanced option that allows users to specify the number of execution(once, twice.) of a loop. The other way requires modifying the XPath of the loop. One way is simply to use "End loop" option from the Advanced Options. There are two basic ways to end a loop in Octoparse. However, many users have questions on the ending of a loop: does a loop end itself when the website reaches the last page or is there a way to end a loop manually? Loop Item is one of the most frequently used actions in Octoparse and comes in handy when dealing with pagination button or load more button.
