Scrape real estate data on Realtor.com – Octoparse

In this tutorial, we are going to introduce how to scrape information from realtor.com.

We will scrape data from the house detail page and scrape the title, location, price, and rating with Octoparse.

To follow through, you may want to use the URL in the tutorial:

https://www.realtor.com/realestateandhomes-search/Tallassee_AL

This tutorial will also cover:

Deal with AJAX for pagination
Locate elements correctly by modifying XPath in Octoparse

Here are the main steps in this tutorial: [Download the demo task file here ]

"Go To Web Page" - open the target web page
Create a pagination loop - scrape all the results from multiple pages
Create a "Loop Item" - loop click into each item on each list
Extract data - select the data for extraction
Start extraction - run the task and get data

1. "Go To Web Page" - open the target web page

Click "+ Task" to start a task using Advanced Mode

Advanced Mode is a highly flexible and powerful web scraping mode. For people who want to scrape from websites with complex structures, like Realtor, we strongly recommend Advanced Mode to start your data extraction project.

Paste the URL into the "Website" box and click "Save URL" to move on

2. Create a pagination loop - scrape all the results from multiple pages

Scroll down and click the ">" button on the web page
Click "Loop click single element" on the "Action Tips" panel

As Realtor loads the content with AJAX, we should set up AJAX Load for the “Pagination” action.

Uncheck "Auto retry when no response"
Check "Load the page with AJAX"
Set up "AJAX Timeout" as "5" seconds

Tips!

3. Create a "Loop Item" - loop click into each item on each list

We are now on the second page. When creating a "Loop Item", we should always start with the first item on the first page. Thus, we'd better go back to the 1st page.

Click "Go To Web Page" in the workflow
Select the pagination loop

By doing this, we can help Octoparse decide the execution order and generate the Loop Item at the appropriate position in the workflow.

Now, let’s build the loop item:

Click the first image item on the web page
Click "Select All" on the "Action Tips" panel
Select "Loop click each element"

We need to set up "AJAX Load" for this step as well since it loads the content with AJAX.

Uncheck "Auto retry when no response"
Uncheck "Open the link in the new tab"
Check "Load the page with AJAX"
Set up "AJAX Timeout" as "5" seconds

4. Extract data - select the data for extraction

Click the information you need on the page
Select "Extract text of the selected element" on the "Action Tips" panel
Rename the fields by selecting from the predefined list or inputting on your own

Tips!

If you want the data to be extracted correctly to the corresponding data fields, you’d better write a new XPath that will always pinpoint the right data on all pages. The related tutorials you might need are listed below.

5. Start extraction - run the task and get data

Click "Save"
Click "Start Extraction" on the upper left side
Select "Local Extraction" to run the task on your computer, or select "Cloud Extraction" to run the task in the Cloud (for premium users only)

For a premium user, Cloud Extraction is highly recommended.
