Php xmlReader vs xmlparser

I know the difference between xmlreader and other tree-based parsers such as simplexml and dom. But what is the difference between xmlreader and xmlparser? Is there any use to using one over the other?

I need to analyze relatively large xml files, affiliate data data about 100M.

XMLReader is a "pull parser". You are responsible for creating a large loop and calling the read () function to move the cursor forward. This software architecture is generally easier to understand intuitively.

XMLParser - , . , , start_element, end_element, character_data, start_namespace_decl .. xml_parse(), Expat XML-, .
