Managed MonoTouch wrapper of the HTML Tidy library

MonoTouch.TidyManaged

This is a managed MonoTouch / iPhone iOS wrapper for the open source, cross-platform Tidy library, a HTML/XHTML/XML markup parser & cleaner originally created by Dave Raggett.

This wrapper is originally created by Mark Beaton. For more informations see Mark Beaton's original project TidyManaged.

For information about Tidy visit Dave Raggett's original web page and the SourceForge project that has taken over maintenance of the library.

libtidy

This wrapper is written in MonoTouch/C#, and makes use of .NET platform invoke (p/invoke) functionality to interoperate with the Tidy library "libtidy.dylib" (written in portable ANSI C) which is part of the iOS operating system libraries and already available on any iPhone with iOS4 or above.

Sample Usage

Here's a quick'n'dirty example using a simple console app.
Note: always remember to .Dispose() of your Document instance (or wrap it in a "using" statement), so the interop layer can clean up any unmanaged resources (memory, file handles etc) when it's done cleaning.

    public static void Execute()
    {
        // vars for tidy results
        string tidyHtml;
        var errorStream = new MemoryStream();
        int warningCount = 0;
        int errorCount = 0;

        // ensure tidy document will be disposed after use 
        // (because tidy needs to be tidy up after use ;-)
        using (Document tidyDoc = Document.FromString("<hTml><title>test</tootle><body>asd</body>"))
        {
            // set some tidy options
            tidyDoc.Quiet = true;
            tidyDoc.OutputXhtml = true;
            tidyDoc.ShowWarnings = true;

            // set error sink to stream
            tidyDoc.SetErrorSink(errorStream);

            // let tidy do it's work
            tidyDoc.CleanAndRepair();

            // check if any HTML errors exist
            if (tidyDoc.RunDiagnostics())
                tidyDoc.ForceOutput = true;

            // get any error and warning count
            warningCount = tidyDoc.WarningCount();
            errorCount = tidyDoc.ErrorCount();

            tidyHtml = tidyDoc.Save();
        }
        // Output any errors and warnings
        errorStream.Position = 0;
        StreamReader sr = new StreamReader(errorStream);
        Console.WriteLine ("Warnings: {0}", warningCount);
        Console.WriteLine ("Errors: {0}", errorCount);
        Console.WriteLine (sr.ReadToEnd());

        // output tidy html
        Console.WriteLine(tidyHtml);
    }
