Nodejs - make sync request and save file in nodejs

I want to make a node script that save in json files some news that i get from a rss feed. I have a objects with some urls and i try to loop over this, make the request and save the file. But i have problems when i make the request because i think of the asyncs nature of node This is the code

var rssUrl = "http://ole.feedsportal.com/c/33068/f/";

var news = {
teamsUrl:{
    river: rssUrl + "577741/index.rss",
    boca: rssUrl + "577729/index.rss"
},

pathToSaveJson: "../public/ajax/news",

getAll: function(req, res){
    for( var i in news.teamsUrl){
        var teamName = i;
        //console.log(teamName);
        console.log(news.teamsUrl[i]);
        request(news.teamsUrl[i] , function(error, response, body){
            console.log(news.teamsUrl[i]);
            parseString(body, function (err, result) {
                //console.log(teamName);                
                var items = result.rss.channel[0].item;
                news.saveJson(items, teamName, res);

            });
        });
    }

},

saveJson: function(items, teamName, res){
    //console.log(teamName);
    var objToSave = [];
    items.forEach(function(value, index){
        // Clean descriptions , delete tags html
        var cleanDescription = value.description[0].split("<")[0];
        var link = value.guid[0]["_"];

        objToSave.push({
            title: value.title[0],
            description: cleanDescription,
            link: link
        })
    });

    fs.writeFile(news.pathToSaveJson + "/" + teamName +".json",  JSON.stringify(objToSave) , function(err){
        if(err) console.log(err);
        console.log("saved filed");
    });
}
}

The first response of console log in the method getAll responds different( works fine) but when i am in the request repeat two times the first and creat only one json file . Any idea?
