There is `printNewsContent()` which is the equivalent function. However, I doubt that this will work for you. Both these functions are "context" sensitive--that is `printPageContent()` will print the content of the current page and `printNewsContent()` will print the content of the current news article. It is not likely that there will be both a news article and a page as the "current context".
From within a codeblock you should be using object methods to refeence specific items. You can use `echo $obj->getContent();` to print the content of a the object in question.
