##HtmlFragmentHelper

HtmlFragmentHelper makes handling Microsoft HTML clipboard format easy in your .NET applications. Written in C#, it parses HTML clipboard metadata in the clipboard and separates it from the HTML source, and further parses the precise source that belongs to the selected html fragment in the clipboard. Each property is then easily accessible from a strongly typed view model, rather than losing them in a blob of text.

HtmlFragmentViewModel also includes a number of convenience methods and properties to make dealing with this data easy. For now, the details are in the source.

The engine of HtmlFragmentHelper lives inside a single file, HtmlFragmentViewModel.cs. To create the view model, you send HtmlFragmentViewModel's constructor the contents of a Microsoft formatted HTML Fragment as a raw string.

###Example usage

public string CreateQuote(string htmlFragmentSource) 
{
    string strIntroLink = string.Empty;
    HtmlFragmentViewModel vm = new HtmlFragmentViewModel(htmlFragmentSource);

    if (vm.SourceUrl.Length > 0 && vm.SourceUrlDomainSecondAndTopLevelsOnly.Length > 0)
    {
        strIntroLink = string.Format("From <a href=\"{0}\">{1}</a>:" + Environment.NewLine + Environment.NewLine,
            vm.SourceUrl, vm.SourceUrlDomainSecondAndTopLevelsOnly);
    }

    return strIntroLink + vm.FragmentSourceParsed;
}

To produce the source for htmlFragmentSource, you'd likely use async code similar to the following:

string src = string.Empty;
DataPackageView dataPackageView = Clipboard.GetContent();

if (dataPackageView.Contains(StandardDataFormats.Html))
{
    src = await Clipboard.GetContent().GetHtmlFormatAsync();
}
else if (dataPackageView.Contains(StandardDataFormats.Text))
{
    src = await Clipboard.GetContent().GetTextAsync();
}
// Else it's a clipboard format we're not handling.

string blockquotedHtml = CreateQuote(src);

The resulting blockquotedHtml might look like this:
