Question 1

How do I handle login-protected websites with DiDOM?

Accepted Answer

DiDOM doesn't handle authentication natively; you'll need to use an HTTP client like Guzzle to manage sessions and cookies, then pass the retrieved HTML to DiDOM for parsing and data extraction.

Question 2

DiDOM vs Simple HTML DOM: which is better for PHP scraping?

Accepted Answer

DiDOM is generally faster and has a cleaner API with better performance due to caching, while Simple HTML DOM is older and slower but might be easier for very basic tasks. For modern projects, DiDOM is often preferred.

Question 3

How to extract all links from a page using DiDOM?

Accepted Answer

Use the find method with a CSS selector, e.g., $document->find('a') to get an array of anchor elements, then loop through and access the href attribute with attr('href') to retrieve the URLs.

Question 4

Can DiDOM parse broken or malformed HTML?

Accepted Answer

Yes, DiDOM uses libxml under the hood, which can handle imperfect HTML, and you can pass libxml options like LIBXML_HTML_NOIMPLIED during loading to control parsing behavior and error tolerance.

Question 5

How to save modified HTML back to a file with DiDOM?

Accepted Answer

After manipulating the document, use the html() method to get the HTML string, then write it to a file using PHP's file_put_contents function, ensuring proper encoding if needed.

Question 6

Does DiDOM support XML namespaces?

Accepted Answer

The README doesn't explicitly cover it, but since DiDOM is built on libxml, it likely supports basic namespace handling via XPath queries, though you may need to use full namespace-aware XPath expressions.
