You can use such code pattern:

bool foobar()
    {
        XmlDocument doc = new XmlDocument();
        try
        {
            doc.Load(FileName);
            XmlNodeList ns = doc.SelectNodes("a/d/e/f");
            if (ns.Count == 1)
            {

                    ns[0].Attributes["visible"].Value = true;
                    doc.Save(FileName);
                    return (true);
            }
            else
                return (false);
        }
        catch (Exception e)
        {
            return (false);
        }
    }
