Exceptions with DateTime parsing in RSS feed in C#

I’m trying to parse Rss2, Atom feeds using SyndicationFeedFormatter and SyndicationFeed objects. But I’m getting XmlExceptions while parsing DateTime field like pubDate and/or lastBuildDate.

Wed, 24 Feb 2010 18:56:04 GMT+00:00 does not work

Wed, 24 Feb 2010 18:56:04 GMT works

So, it’s throwing due to the timezone field.

As a workaround, for familiar feeds I would manually fix those DateTime nodes – by catching the XmlException, loading the Rss into an XmlDocument, fixing those nodes’ value, creating a new XmlReader and then returning the formatter from this new XmlReader object (code not shown). But for this approach to work, I need to know beforehand which nodes cause exception.

        SyndicationFeedFormatter syndicationFeedFormatter = null;
        XmlReaderSettings settings = new XmlReaderSettings();
        using (XmlReader reader = XmlReader.Create(url, settings))
        {
            try
            {
                syndicationFeedFormatter = SyndicationFormatterFactory.CreateFeedFormatter(reader);
                syndicationFeedFormatter.ReadFrom(reader);
            }
            catch (XmlException xexp)
            {
                // fix those datetime nodes with exceptions and read again.
            }
        return syndicationFeedFormatter;
    }

Is there a better way to achieve this? Please help. Thanks.
