Any framework aid for XML parsing?

I am completely new to the XML parsing topic and I would like to ask, if there is any framework class or extension that would allow me read and parse XML file.

Is here any out-of-the-box solution or must one write it itself in i.e. SimpleXML?

What do you need which PHP core libraries does not provide?

I need to “convert” a bit complex XML structure into JSON.

SimpleXML core library does really provide everything that you need. I only wanted to confirm, if I have to craft everything from scratch (loops, finding correct tokens using regular expressions probably etc.) or if there is something ready out-of-the-box in Yii 2.

I don’t like reinventing the wheel idea, so I wanted to double check, if I am not making something like that, before I write my one XML → JASON and XML → model data parsers.

Am not aware of any!
May be check for XML libs for PHP in general
