var originalHtmlString = '<p>Some text</p>'
//Create an html object called myHtml that I can work with like w/ document
var myHtml = document.createElement( 'html' );
//Make the html object hold the html I wrote in a string so I can edit it as html
myHtml.innerHTML = originalHtmlString;
var stringifiedHtml = ???
如何打开&#34; myHtml&#34;使用后var变回一个字符串?
