Save the following program as `rx.cs': + + using System; + using System.Xml; + + class Test { + public static void Main () + { + XmlDocument d = new XmlDocument (); + XmlElement r = d.CreateElement ("Docs"); + d.AppendChild (r); + + XmlElement s = Create (d, "param", "pattern"); + s.AppendChild (Create (d, "para", "insert text here")); + + r.AppendChild (s); + r.AppendChild (Create (d, "param", "pattern")); + r.AppendChild (Create (d, "param", "pattern")); + r.PrependChild (s); + + Console.WriteLine ("OuterXml=" + d.OuterXml); + } + + private static XmlElement Create (XmlDocument d, string name, string param) + { + XmlElement e = d.CreateElement (name); + e.SetAttribute ("name", param); + return e; + } + } + +2. Compile it: mcs rx.cs +3. Run it: mono rx.exe + +Actual Results: + +No output, CPU at 100%. + +Expected Results: + +Either: + +1. An exception stating that you shouldn't insert a node before itself. + +-or- + +2. InsertBefore() silently ignoring an attempt to insert a node before +itself, resulting in the output: + +OuterXml=<Docs><param name="pattern"><para name="insert text here" +/></param><param name="pattern" /><param name="pattern" /></Docs> + +How often does this happen? + +Always. + +Additional Information: + +Tested on Mono 1.1.13.2, 1.1.13.7, and svn-HEAD (circa 2006-12-18). _______________________________________________ mono-bugs maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
