Excuse me, is this html css selector not available now?

I downloaded the source code, but found that the writing method cannot be compiled.

MQL5 is constantly changing, which often breaks compatibility with existing source codes.

Try this one (attached).

Small bug fixes (related to attributes without values) and additions (selection of parent elements by characteristics of child elements and negation condition in attributes - both innovations outside the CSS standard).

and still, I'm interested in the continuation on the topic of parsing using XPath

Given that MQL5 has changed a over the years, maybe the article's code is no longer completely valid and may need some adjustments.

Thanks Fernando for response, I find it for SALE! :)

the reason it is not working as main part of code including classes is not there.

Also the site's code (that's served on the front end) must have changed too .

What are you trying to extract?

Did you read the article?

"If you need help in the setting up of CSS selectors for a specific web page, you can purchase WebDataExtractor (for MetaTrader 4, for MetaTrader 5) and receive recommendations as part of product support. However, the availability of source codes allows you to use the entire functionality and expand it if necessary. This is absolutely free."

As for compilation - it works for me without an error. I'm attaching the source codes.
