I currently have a block "header", which contains a title.
Also I have a page with a data definition that defines such title.

how can I access the current page data definition while im inside the header block?

I have tried the following:
#set( $content = $_XPathTool.selectSingleNode($contentRoot, "/system-data-structure"))
#set( $content = $_XPathTool.selectSingleNode($contentRoot, "/system-folder[system-page[@current]]"))

but it seems I can only access the data definition for the block.
is it possible or I am doing thigs wrong?

   First, is the header block attached to the page in question? If not, how are the two related? If so, is the block attached to a region or a block chooser?

   yes the block is attached to the page in question. and the block belongs to a region.

   Since the block is attached to a region, you loss the context of the hosting page. If you look at $contentRoot, it only contains the XML of the block, not anything related to the hosting page. You will have to use the $currentPage variable to retrieve page content, utilizing the Cascade API. Another option is to attach the block to a block chooser in the page instead. Then you will have to process the block while you are processing the page. The context of the page is given.

   $currentPage.getStructuredDataNode("title")
   

   this did the trick, thank you.
