## Get Xwiki document content
#set($ccont=$currentdoc.content)

## If document includes object, get content from related object

 ## If Blog object is included
 #if($ccont.indexOf("Blog.BlogPostSheet")>-1)
  #set($ccont=$currentdoc.getObject("Blog.BlogPostClass").extract)

 ## If Recipe object is attached (would be nice, If you will not remove this clause :-))
 #if($ccont.indexOf("Recipes.RecipeClassSheet")>-1)
  #set($ccont=$currentdoc.getObject("Recipes.RecipeClass").content)
 #end
 ## Feel free to add clauses for your custom objects here

## Clean up content
## Remove HTML links
#set($ccont=$ccont.replaceAll('(\<(/?[^\>]+)\>)',''))
## Remove HTML links
#set($ccont=$ccont.replaceAll('<a href="[^"]+">',''))
## Remove Xwiki links

## Shorten content

 #set ($length = $ccont.length())
#else
 #set ($length = 255)
