TreeView and SiteMap: How to add a line break?

my sitemap is like:

<?xml version="1.0" encoding="utf-8" ?>
 <siteMap xmlns="http://schemas.microsoft.com/开发者_运维技巧AspNet/SiteMap-File-1.0" >
  <siteMapNode url="~/Admin/Default.aspx" title="Administration"  description="">
   <siteMapNode url="~/Admin/Overview.aspx" title="Übersicht"  description="">
  <siteMapNode url="~/Admin/UserOverview.aspx" title="Benutzer"  description="">
  </siteMapNode>
  <siteMapNode url="~/Admin/CompanyOverview.aspx" title="Firmen"  description="">
  </siteMapNode>
  <siteMapNode url="~/Admin/OrganisationOverview.aspx" title="Organisationen"  description="">
  </siteMapNode>
 </siteMapNode>
  <!-- LINE BREAK SHOULD BE HERE -->
 <siteMapNode url="~/Admin/Settings.aspx"  title="Einstellungen"   description="">

  </siteMapNode>
 </siteMapNode>
</siteMap>

I have a TreeView binded on it with a SiteMapDataSource.

Here is it how it looks like: http://www.imgimg.de/bild_18a9b0128PNG.png.html

How I get a Linebreak in it?

<siteMapNode title="&lt;hr /&gt;"  description="separator" url=""/>
