WebView not working on Android

Hi am making an RSS Feed reader and everything looks good, the app loads the feeds but when i click on one of them it shows the content with HTML tags, for example a bold text it shows it like this: <b> Text </b>

This is my code:

var url="http://arturodiaz.net/feed/";
var WindowWidth = Ti.Platform.displayCaps.platformWidth; 
var WindowHeight = Ti.Platform.displayCaps.platformHeight;
var xhr = Titanium.Network.createHTTPClient();
xhr.open('GET',url);
var data = [];
var WindowWidth = Ti.Platform.displayCaps.platformWidth;
Titanium.UI.setBackgroundColor('#000');
 
 
var tabGroup = Titanium.UI.createTabGroup();
 
var rssWindow = Titanium.UI.createWindow({  
    title:'',
    backgroundColor:'#fff'
});
var rssTab = Titanium.UI.createTab({  
    icon:'KS_nav_views.png',
    title:'Rss Feed',
    window:rssWindow
});
 
tabGroup.addTab(rssTab);  
 
tabGroup.open();
 
xhr.onload = function() {
    //Ti.API.info(this.responseText);
    var xml = this.responseXML;
    var channel = xml.documentElement.getElementsByTagName("channel");
    var title = channel.item(0).getElementsByTagName("title").item(0).text;
    rssWindow.title = title;
    var items = xml.documentElement.getElementsByTagName("item");
    for (var i=0;i<items.length;i++) {
        var this_post_title = items.item(i).getElementsByTagName("title").item(0).text;
        var post_link = items.item(i).getElementsByTagName("link").item(0).text;
        var row = Ti.UI.createTableViewRow({height:'auto',width:WindowWidth,top:0,hasChild: true});
        var post_title = Ti.UI.createLabel({
            text: this_post_title,
            textAlign:'left',
            left:0,
            height:40,
            width:'auto',
            top:3,
            color: 'black'
        }); 
        row.add(post_title);
        row.link = post_link;
        data.push(row);         
    }
    var tv = Titanium.UI.createTableView({
        data:data,
        top:0,
        width:WindowWidth,
        height:WindowHeight
    });
    rssWindow.add(tv);
    tv.addEventListener('click',function(e) {
        var webwin = Titanium.UI.createWindow({
            url: 'showweb.js',
            backgroundColor: '#fff',
            myurl:"http://arturodiaz.net/feed/"
        });
        rssTab.open(webwin);
    });
};
 
xhr.send();

showweb.js

var win = Ti.UI.currentWindow;
var webview = Titanium.UI.createWebView({url:win.myurl});
win.add(webview);
