html - jquery remove nodes and keep children -

i ashamed post question have not managed use of unwrap or replacewith methods in jquery need.

my problem simple : need remove nodes (jquery selectors) of html code without losing children of these nodes.

here jsfiddle demonstrate result of unsightly code used reach goal https://jsfiddle.net/uddaeh1u/15/ (yes it's works...)

// var content : html source code of wysiwyg  var result = ''; $(content).contents().each(function(){     var addcontent = '';     // textnode     if(this.nodetype == 3) {         // text node         result+= $(this).text();     } else if(this.nodetype == 1 && $(this).hasclass('atwho-inserted')) {         // if object node target class         // keep it's contents (means ".atwho-inserted" not kept)         result+= $(this).html();     } else {         // in other case keep entirely         result+= this.outerhtml;     } }); 

could find me better code (with unwrap method) ?

thank lot :)

i think 1 please you. notice modification of var tmp

$(document).ready(function(){    var content = $('.start').html();    $('.startcode code').text(content);        var tmp = $(content);    $('.atwho-inserted', tmp).children().unwrap();    var result = tmp[0].outerhtml; // or tmp.html(); lose outermost tag        $('.result').html(result);    $('.resultcode').text(result);  });

body{    padding:10px;  }  .atwho-inserted{    background-color:red;  }  pre code, .wrap{    white-space: pre-line;  }
