Question

How can I parse HTML tag into Window on android?

I have an HTML tag as below:

<b>Title</b>
<i>Description</i>

I would like to parse this to window without using webview. How could I do so? please give me some suggestion.

var win = Ti.UI.createWindow({
  fullscreen: false
});

win.open();

The result would be:

Title
Description

Answer 1

As scraping web pages can be resource-intensive, if it were me, I would write a web service running on a web server that would retrieve the data for the mobile app, returning the data in json format.

Other people may have alternative views on this however.

Answer 2

I am working with a client that would rather not introduce a server layer at this juncture. Has anybody found a solution for this?

I don't know where you are with this, but I was able to put together a function that pulls content from a particular div on a web site by class:

//Pull HTML content from div tag
function getDivContent(url,className,element) {
    var client = Ti.Network.createHTTPClient();
    //open url
    client.open('GET', url);
    client.onload = function(){
          //get content of url in string
        var doc = this.responseText;
        //create RegEx expresison to search for div tags
        var pattern = new RegExp('<div class=\"' + className + '\">[\\s\\S]*?<\/div>');
        var content = "<head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" /></head><body>" + pattern.exec(doc) + "</body>";
       Ti.API.info('Store: '+ content);
       //replace webview content
       element.html = content;
    }
    client.send();    
}

I then can reference it like so in my ui.js:

var aboutLabelDescription = Titanium.UI.createWebView({
        width:'90%',
        html:'',
        top:20,
        height:'95%',
        borderWidth:10,
        borderColor:'#fff',
        borderRadius:15
});

getDivContent('http://pianocreations.com/about/','entry',aboutLabelDescription);

Just a note that this script may break if you have nested divs within your divs on the html page that you are referencing.
