I think I do need the block api!
The goal is to inspect the first block for having a "class: 'lead'"
But maybe I do not need the second getDocument()?
As you can see in the code below my original code did not loop through all the blocks
I got the page content by (now commented out)
$topicDefenitionDocument.display('topicDescription','view',$topicDefenitionObject)
If I could add .getXDOM().getBlocks("class:ParagraphBlock", "DESCENDANT")) to the object in the above?
The title of the page I was able to get without the privileged API, like you stated.
But the blocks of all class:ParagraphBlock I do need to inspect for the class:'lead'
I do get translated titles when I switch the language
But the blocks retrieved are only in default language?
Did you tried ? getTranslatedDocument() give you the exact same kind
of object you got before calling it, just that it's not the same
document so you do have getXDOM() API too.
...
My current code including the query:
Note the line that works, but will give me
#foreach($t in $topicList)
  #set($topicDefenitionDocs = $services.query.xwql("$topicDefenitionQry2").bindValue("topicreference",$t).addFilter("currentlanguage").execute())
  #if($topicDefenitionDocs != [])
    #foreach($topicDefenitionDoc in $topicDefenitionDocs)
      #set($topicDefenitionDocument=$xwiki.getDocument($topicDefenitionDoc))
      #set($topicDefenitionObject=$topicDefenitionDocument.getObject($classDefenitionName))
      == $topicDefenitionDocument.display('topicTitle','view',$topicDefenitionObject) ==
      ##$topicDefenitionDocument.display('topicDescription','view',$topicDefenitionObject)
      #foreach($ParagraphBlock in $topicDefenitionDocument.getDocument().getTranslatedDocument().getXDOM().getBlocks("class:ParagraphBlock", "DESCENDANT"))
        #if($velocityCount == 1)
          #set ($blockParent = $ParagraphBlock.getParent())
          #set ($leadParagraph = $services.rendering.render($ParagraphBlock, "xwiki/2.1"))
          #if($blockParent.getParameter('class') == 'lead')
           (%class="lead"%)((($leadParagraph)))
          #else
           $leadParagraph
          #end
        #end
      #end
    #end
  #else
    $t

I did as you described.
But nope...
Can it be related to the object I have the .getDocument() method on?
I use XWQL executed with a .addFilter("current language")
On the collection of document-references I get from that query I have a foreach loop.
#foreach($topicDefenitionDoc in $topicDefenitionDocs)
Then I set the variable: #set($topicDefenitionDocument=$xwiki.getDocument($topicDefenitionDoc))
And that variable I use in the 'Block' statement
#foreach($ParagraphBlock in $topicDefenitionDocument.getDocument().getTranslatedDocument().getXDOM().getBlocks("class:ParagraphBlock", "DESCENDANT"))
So I basicly do the getDocument.getTranslatedDocument on a object that is already filtered for current language
It has nothing to do with your query, you get the default language
because you call $xwiki.getDocument with the name of the document
only.
But I did not seen that your initial code was actually wrong,
calling getDocument() twice is useless so the issue does not come from
getTranslatedDocument(), it comes fro your second getDocument() (which
by the way only work for you because you have the right to use
privileged API which you really don't need here).
...
When I remove the getTranslatedDocument() it works, but only gives me the default document language and not the current language
When I add the  getTranslatedDocument() I get empty output

I tied to replace getDocument() in this line with getTranslatedDocument()...
getTranslatedDocument() is a Document API so you should not remove
getDocument(). In other words you get the translated version of that
document so it's getDocument().getTranslatedDocument().
...
#foreach($ParagraphBlock in $topicDefenitionDocument.getDocument().getXDOM().getBlocks("class:ParagraphBlock", "DESCENDANT"))
But the $ParagraphBlock is empty???

I almost have it right I think:

      #set($topicDefenitionDocument=$xwiki.getDocument($topicDefenitionDoc))
      #set($topicDefenitionObject=$topicDefenitionDocument.getObject($classDefenitionName))

        #if($velocityCount == 1)
          #set ($blockParent = $ParagraphBlock.getParent())
          #set ($leadParagraph = $services.rendering.render($ParagraphBlock, "xwiki/2.1"))
          #if($blockParent.getParameter('class') == 'lead')
           (%class="lead"%)((($leadParagraph)))
          #else
           $leadParagraph
          #end
        #end
      #end
The one issue I have left is the translation.
The $topicDefenitionsDocs are in the $context.language
But the Blocks are in the default language?
How can I get the blocks in the $context.language
In document API you have getTranslatedDocument() which return the
right document from current locale point of view on which you can then
call getXDOM().

A little progress, but what to do to inspect if paragraph has class lead to it and to display the paragraph remains unclear.
#foreach($topicDefenitionDoc in $topicDefenitionDocs)

          $ParagraphBlock.self
        #end
        $velocityCount
      #end
    #end
  #else
Will give me a correct count of all html <p> parts
One of these, usually the first is enclosed by a <div class="lead">
I would like to display this text only
$ParagraphBlock.self
But it does only show:
$ParagraphBlock.self
There is no such method in Block so not sure what you expect "self" to
do. If you want to render a block you can use rendering service, see
http://extensions.xwiki.org/xwiki/bin/view/Extension/Rendering+Module.
...
as if method in this context is not valid
Second I have no idea how to inspect the <div class="lead"> that holds the first <p>
My output currently looks as follows:
Behavior
Behavioral problems in people with CdLS are not inevitable. In fact, some people have no behavioral problems, while others are mild, have transient problems. Many problems are treatable. At the same time it is obviously the severity of behavioral problems in people who injure themselves or others deny.
Many behavior problems are a reaction to something in the body or the environment and they are cyclical (they come and go). Behavioral changes often occur in early childhood and the teenage years. Like most people, develop people with CdLS behavior for a certain reason, and it is important to first address the underlying causes of the behavior. If the source of the behavior is determined, one can try to recognize that resource and to avoid.
If the behavior follows a pattern (such as it is always at the same time, same place, or to a particular person) treatment will begin to investigate whether the situation can be changed. When the problem is that the environment does not provide sufficient structure or variation, that can be addressed. Discovering the reasons for behavior is the most difficult part of the treatment. Sometimes one can not eliminate the cause and one should look for ways to control the behavior. This can vary from moment to rest in your own room, distract the person to another activity to the use of protective clothing.
It remains important to always look at possible underlying medical problems. Gastrointestinal problems, muscle pain, ear infections, dental pain and epilepsy can cause irritability, self-injurious behavior or aggressive behavior. Even people who can communicate well, sometimes can not recognize the source of their discontent. Undetected disease (silent reflux) and tooth decay / gum disease are the two most common causes of behavioral changes.

I'm not sure what cased the 503, maybe because I did:
 #foreach($topicDefenitionDoc in $topicDefenitionDocs)
       #set($topicDefenitionDocument=$xwiki.getDocument($topicDefenitionDoc))
       #set($topicDefenitionObject=$topicDefenitionDocument.getObject($classDefenitionName))
       == $topicDefenitionDocument.display('topicTitle','view',$topicDefenitionObject) ==
       #foreach($headerBlock in $topicDefenitionDocument.getXDOM().getBlocks("class:HeaderBlock", ""DESCENDANT"))
         $headerBlock -- to inspect what's inside
       #end
#end
I changed the inside of the loop to $velocityCount and indeed the numbers seemed to allign wel with number of headers inside the page
I've now changed class:HeaderBlock into class:GroupBlock
but now the $velocityCount equals 1 all the time wile my text is like:

I would have expected the  velocity count to number to 4 )equal to number op <p>tags in the text? but it counts only 1

Is this functionality very costly from a performance perspective?
The loop i'm running will give me approx 25 pages
Now I have added the loop through all the Headerblocks and the server crashed (503 service not available)
Now retrying and the page load is very slow: Wating for many minutes now?
Loading 25 pages is slow whatever you do with them, then they are in
cache and it should be OK. I don't see how reading a XDOM could cause
a crash, you should look at the log and see what this 503 really mean.

Note that HeaderBlock is for headers and what you have in your example
in your first mail is a GroupBlock.
Now for the parameters I talked about see
http://nexus.xwiki.org/nexus/service/local/repositories/releases/archive/org...
When you have the block you can as for the value of "class" parameter
using $headerBlock.getParameter('class')
