Question

I want to be able to do something like this :

 //buildArgs
 XmlNode buildArgs = doc.CreateElement("buildArgs");
 XmlAttribute buildArgsAtt = doc.CreateAttribute("-D:project.rc_file");

But I get the fallowing error :

An unhandled exception of type 'System.ArgumentException' occurred in System.Xml.dll

Additional information: Invalid name character in '-D'. The '-' character, hexadecimal value 0x2D, cannot be included in a name.

But I did not choose the format. I am trying to automate the process of adding a new element to cruisecontrol.net config file (ccnet.config). So I need to put that dash there.

This is my code :

   //create new instance of XmlDocument
        XmlDocument doc = new XmlDocument();
        doc.PreserveWhitespace = false;

        //load from file
        doc.Load(filename);

        //create node and add value
        XmlNode projet = doc.CreateNode(XmlNodeType.Element, "projet", null);
        XmlAttribute projetAtt = doc.CreateAttribute("name");
        projetAtt.Value = projectName + " " + oracleVersion;
        projet.Attributes.SetNamedItem(projetAtt);

        ...

        //buildArgs
        XmlNode buildArgs = doc.CreateElement("buildArgs");
        XmlAttribute buildArgsAtt = doc.CreateAttribute("-D:project.rc_file");
        buildArgsAtt.Value = projectName + ".rc";
        XmlAttribute buildArgsAtt2 = doc.CreateAttribute("-D:project.svn_trunk_ver");
        buildArgsAtt2.Value = trunkNb;
        XmlAttribute buildArgsAtt3 = doc.CreateAttribute("-D:project.svn_trunk");
        buildArgsAtt3.Value = trunkPath;
        buildArgs.Attributes.SetNamedItem(buildArgsAtt);
        buildArgs.Attributes.SetNamedItem(buildArgsAtt2);
        buildArgs.Attributes.SetNamedItem(buildArgsAtt3);

        //add to parent node
        projet.AppendChild(nodeWD);
        projet.AppendChild(category);
        projet.AppendChild(trigger);
        trigger.AppendChild(intTrigger);
        projet.AppendChild(sourcecontrol);
        sourcecontrol.AppendChild(trunkUrl);
        sourcecontrol.AppendChild(workingDirectory);
        projet.AppendChild(tasks);
        tasks.AppendChild(nant);
        nant.AppendChild(targetList);
        targetList.AppendChild(target);
        nant.AppendChild(buildArgs);

        //add to elements collection
        doc.DocumentElement.AppendChild(projet);

        XmlWriterSettings settings = new XmlWriterSettings();
        settings.Indent = true;
        settings.NewLineOnAttributes = true;
        settings.Encoding = Encoding.UTF8;

        using (XmlWriter writer = XmlTextWriter.Create(filename, settings))
        {
            doc.Save(writer);
        }

I checked this : Using – in XML element name and others, but I didn’t find an answer that I could use.

-EDIT-

This is an exemple of the ccnet.config :

Thanks!

Answer 1

Which line of the example config? Do you mean this one?

<buildArgs>-D:cvs.executable=c:\putty\cvswithplinkrsh.bat</buildArgs>

That’s not an attribute. It’s element content.
