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'?><rss version="2.0"><channel><title>test</title>
