DOM Document class.
The Document interface represents the entire HTML or XML document. Conceptually, it is the root of the document tree, and provides the primary access to the document's data.
Since elements, text nodes, comments, processing instructions, etc. cannot exist outside the context of a Document, the Document interface also contains the factory methods needed to create these objects. The Node objects created have a ownerDocument attribute which associates them with the Document within whose context they were created.
clan::DomDocument::DomDocument | ( | ) |
Constructs a DOM Document.
clan::DomDocument::DomDocument | ( | IODevice & | input, |
bool | eat_whitespace = true |
||
) |
Constructs a DomDocument.
input | = IODevice |
eat_whitespace | = bool |
clan::DomDocument::DomDocument | ( | const DomString & | namespace_uri, |
const DomString & | qualified_name, | ||
const DomDocumentType & | doctype | ||
) |
clan::DomDocument::DomDocument | ( | const std::shared_ptr< DomNode_Impl > & | impl | ) |
Constructs a DomDocument.
impl | = Shared Ptr |
clan::DomDocument::~DomDocument | ( | ) |
void clan::DomDocument::clear_all | ( | ) |
Removes all nodes from the DOM document.
Creates an Attr of the given name.
Note that the Attr instance can then be set on an Element using the setAttribute method.
name | The name of the attribute. |
DomAttr clan::DomDocument::create_attribute_ns | ( | const DomString & | namespace_uri, |
const DomString & | qualified_name | ||
) |
Creates an attribute of the given qualified name and namespace URI.
Note that the Attr instance can then be set on an Element using the setAttribute method.
DomCDATASection clan::DomDocument::create_cdata_section | ( | const DomString & | data | ) |
Creates a CDATASection node whose value is the specified string.
data | The data for the CDATASection contents. |
DomComment clan::DomDocument::create_comment | ( | const DomString & | data | ) |
Creates a Comment node given the specified string.
data | The data for the node. |
DomDocumentFragment clan::DomDocument::create_document_fragment | ( | ) |
Creates an empty DocumentFragment object.
DomElement clan::DomDocument::create_element | ( | const DomString & | tag_name | ) |
Creates an element of the type specified.
Note that the instance returned implements the Element interface, so attributes can be specified directly on the returned object.
tag_name | The name of the element type to instantiate. For XML, this is case-sensitive. |
DomElement clan::DomDocument::create_element_ns | ( | const DomString & | namespace_uri, |
const DomString & | qualified_name | ||
) |
Creates an element of the given qualified name and namespace URI.
DomEntityReference clan::DomDocument::create_entity_reference | ( | const DomString & | name | ) |

name | The name of the entity to reference. |
DomProcessingInstruction clan::DomDocument::create_processing_instruction | ( | const DomString & | target, |

DomDocumentType clan::DomDocument::get_doctype | ( | ) |
Returns the Document Type Declaration (see DomDocumentType)associated with this document.
For HTML documents as well as XML documents without a document type declaration this returns null. The DOM Level 1 does not support editing the Document Type Declaration, therefore docType cannot be altered in any way.
DomElement clan::DomDocument::get_document_element | ( | ) |
Returns the root document element node.
This is a convenience attribute that allows direct access to the child node that is the root element of the document. For HTML documents, this is the element with the tag name "HTML".
DomElement clan::DomDocument::get_element_by_id | ( | const DomString & | element_id | ) |
Returns the Element whose ID is given by element_id.
DomNodeList clan::DomDocument::get_elements_by_tag_name | ( | const DomString & | tag_name | ) |
Returns a NodeList of all the Elements with a given tag name.
The list is in the order in which they would be encountered in a preorder traversal of the Document tree.
tag_name | The name of the tag to match on. The special value "*" matches all tags. |
DomNodeList clan::DomDocument::get_elements_by_tag_name_ns | ( | const DomString & | namespace_uri, |
const DomString & | qualified_name | ||
) |
Returns a NodeList of all the Elements with a given local name and namespace URI.
The list is in the order in which they would be encountered in a preorder traversal of the Document tree.
DomImplementation clan::DomDocument::get_implementation | ( | ) |
Returns the DomImplementation object that handles this document.
Imports a node from another document to this document.
The returned node has no parent. The source node is not altered or removed from the original document; this method creates a new copy of the source node.
For all nodes, importing a node creates a node object owned by the importing document, with attribute values identical to the source node's node_name and node_type, plus the attributes related to namespaces (prefix, local_name, and namespace_uri). As in the clone_node operation on a Node, the source node is not altered.
std::vector< DomNode > clan::DomDocument::load | ( | IODevice & | input, |
bool | eat_whitespace = true , |
||
DomNode | insert_point = DomNode() |
||
) |
Loads the DOM document as XML from an input source.
input | Input source to read from. |
eat_whitespace | Passed on to XMLTokenizer::set_eat_whitespace. |
insert_point | Place in the DOM to insert the loaded XML code. |
void clan::DomDocument::save | ( | IODevice & | output, |
bool | insert_whitespace = true |
||
) |
Saves the DOM document as XML to an input source.
output | Output source to write to. |
insert_whitespace | Passed on to XMLWriter::set_insert_whitespace. |
