Answer 1

Realtive to your context node $item (I have no doubt there's why you need that context node ;-)) you're looking for ImageSet that a) is a child of ImageSets (which in turn is a direct child of your context node) and b) has the attribute Category with the value primary (which you have coded correctly)

xpath('ImageSets/ImageSet[@Category="primary"]') as $p) {
        echo $p->SwatchImage->URL;
    }
}


function data() {
    return <<< eox

    
      ...
      ...
      
        
          
            ...
            
            
          
          
            ...
            
            
          
        
        
          
            primary swatch image url
            
            
          
          
            ...
            
            
          
        
      
    
    ...
      
eox;
}
