XPath in PHP - Find in Document Specific Element with Id

Question

everyone.

I have an HTML document that contains a very-nested element with a unique ID.

Can XPath find this element? I want to print its inner text.

If not, what do I have to specify? Location in document, tag, etc.?

I've tried to build some queries, but they don't work. I'm not 100% sure what I'm doing.

I'm a bit rusty with XPath, so explanations on how it works would be useful.

Thanks a lot in advance, Gal.

Please read help section on how to ask questions, thank you

"Can XPath find this element?"

Yes it can. Without further details on the context, We can only suggest something like this :

//*[@id='your_unique_id_value_here']

The above XPath means, find all elements (should be only one anyway since id is unique as you described), whatever its name, where id attribute value equals "your_unique_id_value_here".
