web scraping - What Mechanisms Are Used to Cause SeleniumOpenWPM Crawlers to Time Out Excessively and Exit? - Stack Overflow

I’m using Selenium and OpenWPM to crawl and interact with web pages. On certain websites, all elements appear to load successfully, but when I try to grab a specific element (with a certain attribute) and perform a click, the instruction causes a timeout.

Here are some observations:

The elements are dynamically generated, and their classes are non-static (i.e., they change on every page load). Despite the page visually appearing fully loaded, attempting to locate the element using its attribute results in a long delay or a timeout. I suspect this might be due to some dynamic behavior or intentional obfuscation to disrupt automated tools. I’ve tried the following approaches, but they haven’t fully solved the issue:

Using WebDriverWait with presence_of_element_located to ensure the element is loaded before interacting with it. Attempting to locate the element by alternative attributes or XPath. Trying execute_script to interact with the element directly via JavaScript.

Questions: What techniques do websites use to make elements dynamically generated in this way, causing timeouts for automated tools? How can I effectively handle this behavior and interact with elements that have non-static attributes?

Any advice, insights, or recommendations for debugging this problem would be greatly appreciated!

You may follow these below:

1. Enhanced Waiting Strategies:

Use WebDriverWait with expected_conditions like visibility_of_element_located, element_to_be_clickable, or custom conditions to handle dynamic delays.

2. Robust Locators:

Avoid relying on class names or IDs that are non-static. Use XPath or CSS selectors based on unique combinations of attributes or parent-child relationships.

3. Handle AJAX Delays:

Wait for specific JavaScript variables or network requests to complete using execute_script or libraries like requests in Python.

4. JavaScript Interaction:

If standard Selenium methods fail, use execute_script to directly manipulate or interact with the element.

5. Handle Shadow DOM:

If elements are inside a shadow DOM, use Selenium's shadow DOM support or execute_script to access them.

6. Use Explicit Event Waits:

Wait for specific DOM changes or element states using mutation observers or polling loops.
