## Detailed Description

The `DOMDocument` interface represents the entire 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 `DOMDocument`, the `DOMDocument` interface also contains the factory methods needed to create these objects. The `DOMNode` objects created have a `ownerDocument` attribute which associates them with the `DOMDocument` within whose context they were created.

See also the Document Object Model (DOM) Level 2 Core Specification.

## Constructor & Destructor Documentation

## ◆ DOMDocument()

DOMDocument::DOMDocument | ( |  | ) |
| protected

## ◆ ~DOMDocument()

virtual DOMDocument::~DOMDocument | ( |  | ) |
| virtual

Destructor.

## Member Function Documentation

## ◆ adoptNode()

virtual DOMNode * DOMDocument::adoptNode | ( | DOMNode * | source | ) |
| pure virtual

Changes the `ownerDocument` of a node, its children, as well as the attached attribute nodes if there are any.

If the node has a parent it is first removed from its parent child list. This effectively allows moving a subtree from one document to another. The following list describes the specifics for each type of node.

ATTRIBUTE_NODE
  The `ownerElement` attribute is set to `null` and the `specified` flag is set to `true` on the adopted `DOMAttr`. The descendants of the source `DOMAttr` are recursively adopted.
DOCUMENT_FRAGMENT_NODE
  The descendants of the source node are recursively adopted.
DOCUMENT_NODE
  `DOMDocument` nodes cannot be adopted.
DOCUMENT_TYPE_NODE
  `DOMDocumentType` nodes cannot be adopted.
ELEMENT_NODE
  Specified attribute nodes of the source element are adopted, and the generated `DOMAttr` nodes. Default attributes are discarded, though if the document being adopted into defines default attributes for this element name, those are assigned. The descendants of the source element are recursively adopted.
ENTITY_NODE
  `DOMEntity` nodes cannot be adopted.
ENTITY_REFERENCE_NODE
  Only the `DOMEntityReference` node itself is adopted, the descendants are discarded, since the source and destination documents might have defined the entity differently. If the document being imported into provides a definition for this entity name, its value is assigned.
NOTATION_NODE
  `DOMNotation` nodes cannot be adopted.
PROCESSING_INSTRUCTION_NODE, TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE
  These nodes can all be adopted. No specifics.

Parameters

  source | The node to move into this document.

Returns
  The adopted node, or `null` if this operation fails, such as when the source node comes from a different implementation.

Exceptions

  DOMException | NOT_SUPPORTED_ERR: Raised if the source node is of type `DOCUMENT`, `DOCUMENT_TYPE`. NO_MODIFICATION_ALLOWED_ERR: Raised when the source node is readonly.

Since
  DOM Level 3

## ◆ createAttribute()

virtual DOMAttr * DOMDocument::createAttribute | ( | const XMLCh * | name | ) |
| pure virtual

Creates an `DOMAttr` of the given name.

Note that the `DOMAttr` instance can then be set on an `DOMElement` using the `setAttributeNode` method.
To create an attribute with a qualified name and namespace URI, use the `createAttributeNS` method.

Parameters

  name | The name of the attribute.

Returns
  A new `DOMAttr` object with the `nodeName` attribute set to `name`, and `localName`, `prefix`, and `namespaceURI` set to `null`. The value of the attribute is the empty string.

Exceptions

  DOMException | INVALID_CHARACTER_ERR: Raised if the specified name contains an illegal character.

Since
  DOM Level 1

## ◆ createAttributeNS()

virtual DOMAttr * DOMDocument::createAttributeNS | ( | const XMLCh * | namespaceURI,
|  | const XMLCh * | qualifiedName
| ) |  |
| pure virtual

Creates an attribute of the given qualified name and namespace URI.

Parameters

  namespaceURI | The namespace URI of the attribute to create.
  qualifiedName | The qualified name of the attribute to instantiate.

Returns
  A new `DOMAttr` object with the following attributes:

  `Attribute` | `Value`

  `DOMNode.localName` | local name, extracted from `qualifiedName`
  `DOMAttr.name` | `qualifiedName`
  `DOMNode.nodeValue` | the empty string

Exceptions

  DOMException | INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character, per the XML 1.0 specification . NAMESPACE_ERR: Raised if the `qualifiedName` is malformed per the Namespaces in XML specification, if the `qualifiedName` has a prefix and the `namespaceURI` is `null`, if the `qualifiedName` has a prefix that is "xml" and the `namespaceURI` is different from " http://www.w3.org/XML/1998/namespace", or if the `qualifiedName`, or its prefix, is "xmlns" and the `namespaceURI` is different from " http://www.w3.org/2000/xmlns/". NOT_SUPPORTED_ERR: Always thrown if the current document does not support the `"XML"` feature, since namespaces were defined by XML.

| virtual

## ◆ createElement()

virtual DOMElement * DOMDocument::createElement | ( | const XMLCh * | tagName | ) |
| pure virtual

Creates an element of the type specified.

Note that the instance returned implements the `DOMElement` interface, so attributes can be specified directly on the returned object.

| pure virtual

The Document Type Declaration (see `DOMDocumentType`) associated with this document.

For XML documents without a document type declaration this returns `null`. The DOM Level 2 does not support editing the Document Type Declaration. `docType` cannot be altered in any way, including through the use of methods inherited from the `DOMNode` interface, such as `insertNode` or `removeNode`.

Since
  DOM Level 1

## ◆ getDocumentElement()

virtual DOMElement * DOMDocument::getDocumentElement | ( |  | ) | const
| pure virtual

This is a convenience attribute that allows direct access to the child node that is the root element of the document.

Since
  DOM Level 1

## ◆ getDocumentURI()

virtual const XMLCh * DOMDocument::getDocumentURI | ( |  | ) | const

virtual DOMElement * DOMDocument::getElementById | ( | const XMLCh * | elementId | ) | const
| pure virtual

Returns the `DOMElement` whose `ID` is given by `elementId`.

If no such element exists, returns `null`. Behavior is not defined if more than one element has this `ID`. The DOM implementation must have information that says which attributes are of type ID. Attributes with the name "ID" are not of type ID unless so defined. Implementations that do not know whether attributes are of type ID or not are expected to return `null`.

Parameters

  elementId | The unique `id` value for an element.

Returns
  The matching element.

Since
  DOM Level 2

## ◆ getElementsByTagName()

virtual DOMNodeList * DOMDocument::getElementsByTagName | ( | const XMLCh * | tagname | ) | const
| pure virtual

Returns a `DOMNodeList` of all the `DOMElement(s)` with a given tag name in the order in which they are encountered in a preorder traversal of the `DOMDocument` tree.

The returned node list is "live", in that changes to the document tree made after a nodelist was initially returned will be immediately reflected in the node list.

Parameters

  tagname | The name of the tag to match on. The special value "*" matches all tags.

Returns
  A new `DOMNodeList` object containing all the matched `DOMElement(s)`.

Since
  DOM Level 1

Parameters

  namespaceURI | The namespace URI of the elements to match on. The special value "*" matches all namespaces.
  localName | The local name of the elements to match on. The special value "*" matches all local names.

Returns
  A new `DOMNodeList` object containing all the matched `DOMElement(s)`.

Since
  DOM Level 2

## ◆ getImplementation()

virtual DOMImplementation * DOMDocument::getImplementation | ( |  | ) | const
| pure virtual

The `DOMImplementation` object that handles this document.

A DOM application may use objects from multiple implementations.

Since
  DOM Level 1

## ◆ getInputEncoding()

virtual const XMLCh * DOMDocument::getInputEncoding | ( |  | ) | const
| pure virtual

An attribute specifying the encoding used for this document at the time of the parsing.

This is `null` when it is not known, such as when the DOMDocument was created in memory.

Since
  DOM Level 3

## ◆ getStrictErrorChecking()

virtual bool DOMDocument::getStrictErrorChecking | ( |  | ) | const
| pure virtual

An attribute specifying whether errors checking is enforced or not.

When set to `false`, the implementation is free to not test every possible error case normally defined on DOM operations, and not raise any `DOMException`. In case of error, the behavior is undefined. This attribute is `true` by defaults.

Since
  DOM Level 3

## ◆ getXmlEncoding()

virtual const XMLCh * DOMDocument::getXmlEncoding | ( |  | ) | const
| pure virtual

An attribute specifying, as part of the XML declaration, the encoding of this document.

This is `null` when unspecified or when it is not known, such as when the DOMDocument was created in memory.

Since
  DOM Level 3

## ◆ getXmlStandalone()

  DOM Level 3

## ◆ importNode()

virtual DOMNode * DOMDocument::importNode | ( | const DOMNode * | importedNode,
|  | bool | deep
| ) |  |
| pure virtual

Imports a node from another document to this document.

The returned node has no parent; (`parentNode` is `null`). 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 `nodeName` and `nodeType`, plus the attributes related to namespaces (`prefix`, `localName`, and `namespaceURI`). As in the `cloneNode` operation on a `DOMNode`, the source node is not altered.
Additional information is copied as appropriate to the `nodeType`, attempting to mirror the behavior expected if a fragment of XML source was copied from one document to another, recognizing that the two documents may have different DTDs in the XML case. The following list describes the specifics for each type of node.

ATTRIBUTE_NODE
  The `ownerElement` attribute is set to `null` and the `specified` flag is set to `true` on the generated `DOMAttr`. The descendants of the source `DOMAttr` are recursively imported and the resulting nodes reassembled to form the corresponding subtree. Note that the `deep` parameter has no effect on `DOMAttr` nodes; they always carry their children with them when imported.
DOCUMENT_FRAGMENT_NODE
  If the `deep` option was set to `true`, the descendants of the source element are recursively imported and the resulting nodes reassembled to form the corresponding subtree. Otherwise, this simply generates an empty `DOMDocumentFragment`.
DOCUMENT_NODE
  `DOMDocument` nodes cannot be imported.
DOCUMENT_TYPE_NODE
  `DOMDocumentType` nodes cannot be imported.
ELEMENT_NODE
  Specified attribute nodes of the source element are imported, and the generated `DOMAttr` nodes are attached to the generated `DOMElement`. Default attributes are not copied, though if the document being imported into defines default attributes for this element name, those are assigned. If the `importNode` `deep` parameter was set to `true`, the descendants of the source element are recursively imported and the resulting nodes reassembled to form the corresponding subtree.
ENTITY_NODE
  `DOMEntity` nodes can be imported, however in the current release of the DOM the `DOMDocumentType` is readonly. Ability to add these imported nodes to a `DOMDocumentType` will be considered for addition to a future release of the DOM.On import, the `publicId`, `systemId`, and `notationName` attributes are copied. If a `deep` import is requested, the descendants of the the source `DOMEntity` are recursively imported and the resulting nodes reassembled to form the corresponding subtree.
ENTITY_REFERENCE_NODE
  Only the `DOMEntityReference` itself is copied, even if a `deep` import is requested, since the source and destination documents might have defined the entity differently. If the document being imported into provides a definition for this entity name, its value is assigned.
NOTATION_NODE
  `DOMNotation` nodes can be imported, however in the current release of the DOM the `DOMDocumentType` is readonly. Ability to add these imported nodes to a `DOMDocumentType` will be considered for addition to a future release of the DOM.On import, the `publicId` and `systemId` attributes are copied. Note that the `deep` parameter has no effect on `DOMNotation` nodes since they never have any children.
PROCESSING_INSTRUCTION_NODE
  The imported node copies its `target` and `data` values from those of the source node.
TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE
  These three types of nodes inheriting from `DOMCharacterData` copy their `data` and `length` attributes from those of the source node.

Parameters

  importedNode | The node to import.
  deep | If `true`, recursively import the subtree under the specified node; if `false`, import only the node itself, as explained above. This has no effect on `DOMAttr` , `DOMEntityReference`, and `DOMNotation` nodes.

Returns
  The imported node that belongs to this `DOMDocument`.

Exceptions

  DOMException | NOT_SUPPORTED_ERR: Raised if the type of node being imported is not supported.

## ◆ normalizeDocument()

virtual void DOMDocument::normalizeDocument | ( |  | ) |
| pure virtual

This method acts as if the document was going through a save and load cycle, putting the document in a "normal" form.

The actual result depends on the features being set. See `DOMConfiguration` for details.

Noticeably this method normalizes `DOMText` nodes, makes the document "namespace wellformed", according to the algorithm described below in pseudo code, by adding missing namespace declaration attributes and adding or changing namespace prefixes, updates the replacement tree of `DOMEntityReference` nodes, normalizes attribute values, etc.
Mutation events, when supported, are generated to reflect the changes occurring on the document. Note that this is a partial implementation. Not all the required features are implemented. Currently `DOMAttr` and `DOMText` nodes are normalized. Features to remove `DOMComment` and `DOMCDATASection` work.

## ◆ renameNode()

virtual DOMNode * DOMDocument::renameNode | ( | DOMNode * | n,
|  | const XMLCh * | namespaceURI,
|  | const XMLCh * | qualifiedName
| ) |  |
| pure virtual

Rename an existing node.

When possible this simply changes the name of the given node, otherwise this creates a new node with the specified name and replaces the existing node with the new node as described below. This only applies to nodes of type `ELEMENT_NODE` and `ATTRIBUTE_NODE`.
When a new node is created, the following operations are performed: the new node is created, any registered event listener is registered on the new node, any user data attached to the old node is removed from that node, the old node is removed from its parent if it has one, the children are moved to the new node, if the renamed node is an `DOMElement` its attributes are moved to the new node, the new node is inserted at the position the old node used to have in its parent's child nodes list if it has one, the user data that was attached to the old node is attach to the new node, the user data event `NODE_RENAMED` is fired.
When the node being renamed is an `DOMAttr` that is attached to an `DOMElement`, the node is first removed from the `DOMElement` attributes map. Then, once renamed, either by modifying the existing node or creating a new one as described above, it is put back.

Parameters

  n | The node to rename.
  namespaceURI | The new namespaceURI.
  qualifiedName | The new qualified name.

Returns
  The renamed node. This is either the specified node or the new node that was created to replace the specified node.

Exceptions

  DOMException | NOT_SUPPORTED_ERR: Raised when the type of the specified node is neither `ELEMENT_NODE` nor `ATTRIBUTE_NODE`. WRONG_DOCUMENT_ERR: Raised when the specified node was created from a different document than this document. NAMESPACE_ERR: Raised if the `qualifiedName` is malformed per the Namespaces in XML specification, if the `qualifiedName` has a prefix and the `namespaceURI` is `null`, or if the `qualifiedName` has a prefix that is "xml" and the `namespaceURI` is different from " http://www.w3.org/XML/1998/namespace" . Also raised, when the node being renamed is an attribute, if the `qualifiedName`, or its prefix, is "xmlns" and the `namespaceURI` is different from "http://www.w3.org/2000/xmlns/".

## ◆ setDocumentURI()

virtual void DOMDocument::setDocumentURI | ( | const XMLCh * | documentURI | ) |
| pure virtual

The location of the document or `null` if undefined.

Beware that when the `DOMDocument` supports the feature "HTML" , the href attribute of the HTML BASE element takes precedence over this attribute.

Since
  DOM Level 3

## ◆ setStrictErrorChecking()

virtual void DOMDocument::setStrictErrorChecking | ( | bool | strictErrorChecking | ) |
| pure virtual

An attribute specifying whether errors checking is enforced or not.

When set to `false`, the implementation is free to not test every possible error case normally defined on DOM operations, and not raise any `DOMException`. In case of error, the behavior is undefined. This attribute is `true` by defaults.

Since
  DOM Level 3

## ◆ setXmlStandalone()

virtual void DOMDocument::setXmlStandalone | ( | bool | standalone | ) |
| pure virtual

An attribute specifying, as part of the XML declaration, whether this document is standalone.

This attribute represents the property [standalone] defined in .

Since
  DOM Level 3

## ◆ setXmlVersion()

virtual void DOMDocument::setXmlVersion | ( | const XMLCh * | version | ) |
| pure virtual

An attribute specifying, as part of the XML declaration, the version number of this document.

This is `null` when unspecified.
This attribute represents the property [version] defined in .
