title: TYPO3: Get rootline level with page ID in fluid - maybe in viewhelper
body: <p>i want to get the rootline level from an page with the ID X.
  For example: Page2.1 with the ID 233 -> rootline level = 4.</p>
  
  <p>From this point, i want to get the page id from the parent page in the rootlevel 2.</p>
  
  <p>The reason:
  I have a multilanguage webpage with many childpages - like this example:</p>
  
  <pre><code>[root]
   |- Umbrella Brand-1
     |-country1
        |-page1[200] -&gt; relation to page1[400]
        |-page2[201]
           |-page2.1[203] -&gt; relation to page 2.1[233]
        |-page3[202]
     |-country2
        |-page1[230]
        |-page2[231]
           |-page2.1[233]
        |-page3[232]
  |- Umbrella Brand-2
     |-country1
        |-page1[400]
        |-page2[401]
           |-page2.1[403]
        |-page3[402]
     |-country2
        |-page1[430]
        |-page2[231]
           |-page2.1[233]
        |-page3[232]
  </code></pre>
  
  <p>I want to build relation between pages in diffrent countrys, maybe it's a about page. With this relations, i build an country select menu. Here is the background, that by an countrychange the same page open, from where i come. For example: page1[200] -country change->page1[400].</p>
  
  <p>I hope that anyone know what i mean. 
  Sorry for this bad english.</p>
