◆ clone_node()

template<class Ch = char>

xml_node< Ch > * clone_node	(	const xml_node< Ch > *	source,
		xml_node< Ch > *	result = 0 )

inline

Clones an xml_node and its hierarchy of child nodes and attributes. Nodes and attributes are allocated from this memory pool. Names and values are not cloned, they are shared between the clone and the source. Result node can be optionally specified as a second parameter, in which case its contents will be replaced with cloned source node. This is useful when you want to clone entire document.

Parameters

source	Node to clone.
result	Node to put results in, or 0 to automatically allocate result node

Returns: Pointer to cloned node. This pointer will never be NULL.
