What is the equivalent of TiXmlAttribute for tinyxml2 and how to use it?

I've encountered a problem that I'm not being able to solve using tinyxml2.

I have a function that receives as a parameter a XMLElement and I need to iterate over its attributes. With tinyxml, this worked:

void xmlreadLight(TiXmlElement* light){
    for (TiXmlAttribute* a = light->FirstAttribute(); a ; a = a->Next()) {
         //Do stuff
    }
}

Using the same with tinyxml2, like in the example below, I get the following error:

a value of type const tinyxml2::XMLAttribute * cannot be used to initialize an entity of type tinyxml2::XMLAttribute *

void xmlreadLight(XMLElement* light){
    for (XMLAttribute* a = light->FirstAttribute(); a ; a = a->Next()) {
         //Do stuff
    }
}

The XML code in question is:

<lights>
   <light type="POINT" posX=-1.0 posY=1.0 posZ=-1.0 ambtR=1.0 ambtG=1.0 ambtB=1.0 />
</lights>

where light is the XMLElement passed into the function xmlreadLight. Not sure if my question is properly set up, so if theres some info missing, let me know.

Going by the error message, it looks like you need to do:

for (const XMLAttribute* a = light->FirstAttribute(); a ; a = a->Next()) { ...
     ^^^^^

Presumbably, the return type of FirstAttribute has been made const in tinyxml2.

If you check the Github repository for the tinyxml2.h file on line 1513 you will see this:

/// Return the first attribute in the list.
const XMLAttribute* FirstAttribute() const {
    return _rootAttribute;
}
