Hi! I'm creating a mobile app of existing webpage. I used HTMLAGILITYPACK to scrap some of data for web page and I'd like to display that data in my app.
Here is my 'scrapper':
namespace Apka
{
public partial class App : Application
{
public static string DocumentPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
public static string strona = "";
public static NavigationPage NavigationPage { get; private set; }
WebRequest request = HttpWebRequest.Create("wiocha.pl");
WebResponse response;
public App()
{
InitializeComponent();
starthttp();
NavigationPage = new NavigationPage(new MainPage());
RootPage rootPage = new RootPage();
MenuPage menuPage = new MenuPage(rootPage.vm);
rootPage.Master = menuPage;
rootPage.Detail = NavigationPage;
MainPage = rootPage;
}
private async void starthttp()
{
response = await Task.Factory.FromAsync<WebResponse>(request.BeginGetResponse, request.EndGetResponse, null);
var html = new HtmlDocument();
html.Load(response.GetResponseStream());
var nodes = html.DocumentNode.Descendants("img")
.Where(node => node.GetAttributeValue("class", "")
.Equals("imageitself")).ToList();
foreach (var node in nodes)
{
strona = strona + node.OuterHtml;
}
System.Diagnostics.Debug.WriteLine(strona);
}
}
}
The result of it printed in console is some of img like:
<img src=''link(i cant paste link because im a new here)'' class=imageitself alt=''blablabla''>
Next, I'm trying to display it on main page so i do something like that:
namespace Apka.View.Pages
{
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class MainPage : ContentPage
{
public MainPage()
{
InitializeComponent();
WebView webView = new WebView
{
Source = new HtmlWebViewSource
{
Html = @"<!DOCTYPE html><html><head><style>img { width:100%; }</style><body>" + App.strona + @"</body></html>",
},
VerticalOptions = LayoutOptions.FillAndExpand
};
/* ViewModel.Pages.MainPageViewModel vm = new ViewModel.Pages.MainPageViewModel();
this.BindingContext = vm;*/
}
}
}
XAML of this page looks like that:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="" (again i cant paste link)
xmlns:x="" (here too)
x:Class="Apka.View.Pages.MainPage">
<ContentPage.ToolbarItems>
<ToolbarItem Command="{Binding MenuItem1Command}" />
</ContentPage.ToolbarItems>
<ContentPage.Content>
<StackLayout BackgroundColor="#505050" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">
</StackLayout>
</ContentPage.Content>
</ContentPage>
The problem is, it does nothing. I run app and webview doesn't work. What should I do to display these images on my page.
