使用XPath查找范圍的第四個父Div

const getnodes=function( expr, parent ){
        let results=[];
        let contextNode=parent || document;
        let query=document.evaluate( expr, contextNode, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null );
        for ( let i=0, length=query.snapshotLength; i < length; ++i ) {
            results.push( query.snapshotItem( i ) );
        }
        return results;
    };
  
  let col=getnodes( '//span[ text()="some text" ]/../../../../../div', document.body );
  col.forEach( n=>console.info( n.textContent ) )

<!--This is the div I want to select -->
  <div>top
    <div>a
        <div>b
            <div>c
                <span>some text</span>
             </div>
         </div>
    </div>
  </div>
