有了这些信息，我只能跟着

  var objectHTMLCollection = document.getElementsByTagName（div），
 string = [] .map.call（objectHTMLCollection，function（node）{
 return node.textContent || node.innerText ||; 
}）。join（）; 
 

I am trying to use data extracted from a XML file by getElementByTagName and it returns HTML Collection Object but I need this data for a sending a REST request so I need to get the HTML Collection Object to be converted into a string. How can it be done?

Here's more information:

com_zimbra_om.prototype._responseHandler=
        function(response){
                try{
                    sid = response.xml.getElementsByTagName("session_id");
                    this.login_user();
                    }catch(e){
                            this._showErrorMsg(e);
                            }

Using this function I am trying to get the session_id from a REST response. Here sid (global variable) is the HTML Collection Object. Now when I try to use this in the next function:

com_zimbra_om.prototype.login_user = function(){
var url = selected_server + 'services/UserService/loginUser?SID=' +
                                    sid + '&username='+
                                    selected_username +
                                    '&userpass=' + 
                                    selected_password;
                var request_url = ZmZimletBase.PROXY + AjxStringUtil.urlComponentEncode(url);

So here I am using sid which I need as a string.

So how should I convert HTML Collection Object into string??

Thanks

With this information I can only go with

var objectHTMLCollection = document.getElementsByTagName("div"),
    string = [].map.call( objectHTMLCollection, function(node){
        return node.textContent || node.innerText || "";
    }).join("");
