__dom_text_destroy()

void __dom_text_destroy

(

dom_node_internal *

node

)

_dom_text_copy()

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

_dom_text_copy_internal()

dom_exception _dom_text_copy_internal	(	dom_text *	old,
		dom_text *	new
	)

_dom_text_create()

dom_exception _dom_text_create	(	dom_document *	doc,
		dom_string *	name,
		dom_string *	value,
		dom_text **	result
	)

Create a text node

Parameters

doc	The owning document
name	The name of the node to create
value	The text content of the node
result	Pointer to location to receive created node

Returns

DOM_NO_ERR on success, DOM_NO_MEM_ERR on memory exhaustion.

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

The returned node will already be referenced.

_dom_text_destroy()

void _dom_text_destroy

(

dom_text *

text

)

Destroy a text node

Parameters

doc	The owning document
text	The text node to destroy

The contents of ::text will be destroyed and ::text will be freed.

_dom_text_finalise()

void _dom_text_finalise

(

dom_text *

text

)

Finalise a text node

Parameters

doc	The owning document
text	The text node to finalise

The contents of ::text will be cleaned up. ::text will not be freed.

_dom_text_get_is_element_content_whitespace()

dom_exception _dom_text_get_is_element_content_whitespace	(	dom_text *	text,
		bool *	result
	)

Determine if a text node contains element content whitespace

Parameters

text	The node to consider
result	Pointer to location to receive result

Returns

DOM_NO_ERR.

_dom_text_get_whole_text()

dom_exception _dom_text_get_whole_text	(	dom_text *	text,
		dom_string **	result
	)

Retrieve all text in Text nodes logically adjacent to a Text node

Parameters

text	Text node to consider
result	Pointer to location to receive result

Returns

DOM_NO_ERR.

_dom_text_initialise()

dom_exception _dom_text_initialise	(	dom_text *	text,
		dom_document *	doc,
		dom_node_type	type,
		dom_string *	name,
		dom_string *	value
	)

Initialise a text node

Parameters

text	The node to initialise
doc	The owning document
type	The type of the node
name	The name of the node to create
value	The text content of the node

Returns

DOM_NO_ERR on success.

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

_dom_text_replace_whole_text()

dom_exception _dom_text_replace_whole_text	(	dom_text *	text,
		dom_string *	content,
		dom_text **	result
	)

Replace the text of a Text node and all logically adjacent Text nodes

Parameters

text	Text node to consider
content	Replacement content
result	Pointer to location to receive Text node

Returns

DOM_NO_ERR on success, DOM_NO_MODIFICATION_ALLOWED_ERR if one of the Text nodes being replaced is readonly.

The returned node will be referenced. The client should unref the node once it has finished with it.

_dom_text_split_text()

dom_exception _dom_text_split_text	(	dom_text *	text,
		uint32_t	offset,
		dom_text **	result
	)

Split a text node at a given character offset

Parameters

text	The node to split
offset	Character offset to split at
result	Pointer to location to receive new node

Returns

DOM_NO_ERR on success, DOM_INDEX_SIZE_ERR if ::offset is greater than the number of characters in ::text, DOM_NO_MODIFICATION_ALLOWED_ERR if ::text is readonly.

The returned node will be referenced. The client should unref the node once it has finished with it.
