function fetchsearchresults(json) {      var feedentriesdivelement = document.getelementbyid('feedentries');      var ulelement = document.createelement('ul');        if (feedentriesdivelement.children.length >= 0)     {         // syntax code remove code/data              }        (var = 0; < json.responsedata.results.length; i++)     {         var lielement = document.createelement('li');                var persontext = document.createtextnode(json.responsedata.results[i].titlenoformatting);         var newlink = document.createelement('a');          newlink.setattribute('href', json.responsedata.results[i].url );                  newlink.appendchild(persontext);         lielement.appendchild(newlink);         ulelement.appendchild(lielement);     }      feedentriesdivelement.appendchild(ulelement); } 

using pure dom , javascript (sometimes considered better altering innerhtml):

if ( feedentriesdivelement.haschildnodes() ) {     while ( feedentriesdivelement.childnodes.length >= 1 )     {         feedentriesdivelement.removechild( feedentriesdivelement.firstchild );            }  }
