Format XmlDocument newline

Hi Experts,

My XmlDocument doesn't include any NewLine char.
So when I use:
System.Diagnostics.Debug.WriteLine(xmlDocument.OuterXml);
Then the text is written on 1 line.

I want the same XmlDocument to be formatted and displayed on several lines (each node on 1 line).

I don't want to rewrite all the XmlDocument: I want to format it at the end of the building.

Thanks in advance for your help.

If its just for presentation (into a text box, for example), maybe a Regular Expression replace might help to start.  Something like:

    private void TryMe()
    {
        Regex regEx = new Regex("</.+?>", RegexOptions.Multiline | RegexOptions.ECMAScript);
        string outXml = regEx.Replace(xmlDoc.OuterXml, new MatchEvaluator(InsertNewLine));
        Debug.WriteLine(outXml);
    }

    private string InsertNewLine(Match m)
    {
        return string.Format("{0}{1}", m, Environment.NewLine);
    }

Thanks for this quick answer jimbobmcgee.

Your code achieve a part of the job, so we are near the final solution.
I get this formatting:
<item><subitem1></subitem1>
<subitem2></subitem2>
<subitem3> </subitem3>
<subitem4></subitem4>
</item>

I'd like this:
<item>
<subitem1></subitem1>
<subitem2></subitem2>
<subitem3> </subitem3>
<subitem4></subitem4>
</item>

And my first line is something like this,  so no formatting:
<?xml version="1.0" encoding="utf-8"?><?xml-stylesheet type='text/xsl' href='/rss.xsl' version='1.0'?><!--description--><rss version="2.0"><channel><title>test</title>

Don't think you'll get it in one RegEx, so maybe three might do it:

    private void TryMe()
    {
        Regex regExDecs = new Regex("(?'decs'<(\?)(.+?)/title>)(?'rest'.*)", RegexOptions.Multiline | RegexOptions.ECMAScript);
        Regex regExRoot = new Regex("(?'root'<[\w]*>)[\s]*(?'first'<[\w]*>)", RegexOptions.Multiline | RegexOptions.ECMAScript);
        Regex regExOthers = new Regex("</.+?>", RegexOptions.Multiline | RegexOptions.ECMAScript);

        Match decsMatch = reExDecs.Match(xmlDoc.OuterXml);
        string outXml = decsMatch.Groups[4].Value;
        outXml = regExRoot.Replace(xmlDoc.OuterXml, new MatchEvaluator(InsertRootNewLine));
        outXml = regExOthers.Replace(outXml, new MatchEvaluator(InsertNewLine));

        Debug.WriteLine(outXml);
    }

    private string InsertRootNewLine(Match m)
    {
        return string.Format("{0}{1}{2}", m.Groups[1].Value, Environment.NewLine, m.Groups[2].Value);
    }

    private string InsertNewLine(Match m)
    {
        return string.Format("{0}{1}", m, Environment.NewLine);
    }
