How to get a node content programmatically? I am writing a module, in which I am required to display contents from multiple nodes. Using the configs I save, I will get the node id's in hook_block_view. Using that is there a way to get the contents of the particular node, so that I can manipulate on that?
Assuming by 'contents' you mean the HTML for the node in a particular view mode, you're looking for node_view():


  Generates an array for rendering the given node.


e.g.

$node = node_load(1);
$view = node_view($node, 'full');
$rendered = drupal_render($view);
