Allows to get a copy for the content stored inside the given axlNode reference.
This function works the same way than axl_node_get_content but returning a copy from the internal content, that the caller is responsible of deallocating it.
- Parameters:
-
| node | The axlNode where the content is being required. |
| content_size | An optinal reference to an integer variable where the content size will be returned. The function will return the content size (if the variable is defined) ranging from 0 up to the content size. |
- Returns:
- A newly allocated string representing the node content.
