How to read og:title? RRS feed

  • Question

  • Hi,

    Using below code I am able ot read website Title but I want to know how can I read og:title because most of social media read the og:title and ig not available then I will read the title

    How can I grab the og:title?

    I tried below code but not getting it. Although the highlighted line works perfectly for Title like this:

    readonly Regex regex = new Regex(@"\<title\b[^>]*\>\s*(?<Title>[\s\S]*?)\</title\>", RegexOptions.IgnoreCase);

    Here is the code:

    private async void Button2_Clicked(object sender, EventArgs e)
        // Temp Counter to be Removed;
        string website = EntryURL.Text;
        var st = Stopwatch.StartNew();
        string title = await GetTitle(website);
        LabelWebsiteTitle.Text = title + $"elapsed: {st.ElapsedMilliseconds}ms";
    readonly Regex regex = new Regex(@"\<og:title\b[^>]*\>\s*(?<Title>[\s\S]*?)\</og:title\>", RegexOptions.IgnoreCase);
    async Task<string> GetTitle(string website)
        using (var hc = new HttpClient())
            var response = await hc.GetAsync(new Uri(website, UriKind.Absolute))
            string source = await response.Content.ReadAsStringAsync()
            return regex.Match(source)

    Besides, it is not reliable to parse HTML with regular expressions.
