Function Documentation

_dom_characterdata_append_data()

dom_exception _dom_characterdata_append_data	(	struct dom_characterdata *	cdata,
		dom_string *	data
	)

Append data to the end of a character data node's content

Parameters

cdata	The node to append data to
data	The data to append

Returns

DOM_NO_ERR on success, DOM_NO_MODIFICATION_ALLOWED_ERR if cdata is readonly.

_dom_characterdata_copy()

dom_exception _dom_characterdata_copy	(	dom_node_internal *	old,
		dom_node_internal **	copy
	)

_dom_characterdata_copy_internal()

dom_exception _dom_characterdata_copy_internal	(	dom_characterdata *	old,
		dom_characterdata *	new
	)

_dom_characterdata_create()

_dom_characterdata_delete_data()

dom_exception _dom_characterdata_delete_data	(	struct dom_characterdata *	cdata,
		uint32_t	offset,
		uint32_t	count
	)

Delete data from a character data node's content

Parameters

cdata	The node to delete from
offset	The character offset to start deletion from
count	The number of characters to delete

Returns

DOM_NO_ERR on success, DOM_INDEX_SIZE_ERR if offset is negative or greater than the number of characters in cdata or count is negative, DOM_NO_MODIFICATION_ALLOWED_ERR if cdata is readonly.

_dom_characterdata_destroy()

struct dom_node_internal *

node

)

_dom_characterdata_finalise()

void _dom_characterdata_finalise

(

struct dom_characterdata *

cdata

)

Finalise a character data node

Parameters

cdata

The node to finalise

The contents of cdata will be cleaned up. cdata will not be freed.

_dom_characterdata_get_data()

dom_exception _dom_characterdata_get_data	(	struct dom_characterdata *	cdata,
		dom_string **	data
	)

Retrieve data from a character data node

Parameters

cdata	Character data node to retrieve data from
data	Pointer to location to receive data

Returns

DOM_NO_ERR.

The returned string will have its reference count increased. It is the responsibility of the caller to unref the string once it has finished with it.

DOM3Core states that this can raise DOMSTRING_SIZE_ERR. It will not in this implementation; dom_strings are unbounded.

_dom_characterdata_get_length()

dom_exception _dom_characterdata_get_length	(	struct dom_characterdata *	cdata,
		uint32_t *	length
	)

Get the length (in characters) of a character data node's content

Parameters

cdata	Node to read content length of
length	Pointer to location to receive character length of content

Returns

DOM_NO_ERR.

_dom_characterdata_get_text_content()

dom_exception _dom_characterdata_get_text_content	(	dom_node_internal *	node,
		dom_string **	result
	)

_dom_characterdata_initialise()

dom_exception _dom_characterdata_initialise	(	struct dom_characterdata *	cdata,
		struct dom_document *	doc,
		dom_node_type	type,
		dom_string *	name,
		dom_string *	value
	)

Initialise a character data node

Parameters

cdata	The character data node to initialise
doc	The document which owns the node
type	The node type required
name	The node name, or NULL
value	The node value, or NULL

Returns

DOM_NO_ERR on success.

doc, name and value will have their reference counts increased.

_dom_characterdata_insert_data()

dom_exception _dom_characterdata_insert_data	(	struct dom_characterdata *	cdata,
		uint32_t	offset,
		dom_string *	data
	)

Insert data into a character data node's content

Parameters

cdata	The node to insert into
offset	The character offset to insert at
data	The data to insert

Returns

DOM_NO_ERR on success, DOM_INDEX_SIZE_ERR if offset is negative or greater than the number of characters in cdata, DOM_NO_MODIFICATION_ALLOWED_ERR if cdata is readonly.

_dom_characterdata_replace_data()

dom_exception _dom_characterdata_replace_data	(	struct dom_characterdata *	cdata,
		uint32_t	offset,
		uint32_t	count,
		dom_string *	data
	)

Replace a section of a character data node's content

Parameters

cdata	The node to modify
offset	The character offset of the sequence to replace
count	The number of characters to replace
data	The replacement data

Returns

DOM_NO_ERR on success, DOM_INDEX_SIZE_ERR if offset is negative or greater than the number of characters in cdata or count is negative, DOM_NO_MODIFICATION_ALLOWED_ERR if cdata is readonly.

_dom_characterdata_set_data()

dom_exception _dom_characterdata_set_data	(	struct dom_characterdata *	cdata,
		dom_string *	data
	)

Set the content of a character data node

Parameters

cdata	Node to set the content of
data	New value for node

Returns

DOM_NO_ERR on success, DOM_NO_MODIFICATION_ALLOWED_ERR if cdata is readonly.

The new content will have its reference count increased, so the caller should unref it after the call (as the caller should have already claimed a reference on the string). The node's existing content will be unrefed.

_dom_characterdata_set_text_content()

dom_exception _dom_characterdata_set_text_content	(	dom_node_internal *	node,
		dom_string *	content
	)

_dom_characterdata_substring_data()

dom_exception _dom_characterdata_substring_data	(	struct dom_characterdata *	cdata,
		uint32_t	offset,
		uint32_t	count,
		dom_string **	data
	)

Extract a range of data from a character data node

Parameters

cdata	The node to extract data from
offset	The character offset of substring to extract
count	The number of characters to extract
data	Pointer to location to receive substring

Returns

DOM_NO_ERR on success, DOM_INDEX_SIZE_ERR if offset is negative or greater than the number of characters in cdata or count is negative.

The returned string will have its reference count increased. It is the responsibility of the caller to unref the string once it has finished with it.

DOM3Core states that this can raise DOMSTRING_SIZE_ERR. It will not in this implementation; dom_strings are unbounded.
