replaceChild Method
Replaces the specified old child node with the supplied new child node.
var objXMLDOMNode = oXMLDOMNode.replaceChild(newChild, oldChild);
HRESULT replaceChild(
IXMLDOMNode* newChild,
IXMLDOMNode* oldChild,
IXMLDOMNode** outOldChild
);
General Remarks
This operation depends on the value of the nodeType property.
NODE_ATTRIBUTE
This operation depends on the value of the newChild parameter:
| Value | Description |
|---|---|
| NODE_ATTRIBUTE, NODE_CDATA_SECTION, NODE_COMMENT, NODE_DOCUMENT, NODE_DOCUMENT_TYPE, NODE_ELEMENT, NODE_ENTITY, NODE_NOTATION, NODE_PROCESSING_INSTRUCTION | Returns an error. These node types cannot be children of an attribute. |
| NODE_DOCUMENT_FRAGMENT | Replaces oldChild with the children of the document fragment in newChild and returns oldChild. |
| NODE_ENTITY_REFERENCE, NODE_TEXT | Replaces the specified oldChild with the supplied newChild and returns oldChild. |
| NODE_CDATA_SECTION, NODE_COMMENT, NODE_ENTITY, NODE_NOTATION, NODE_PROCESSING_INSTRUCTION, NODE_TEXT | Returns an error. These node types either cannot have children or their children are read-only. |
NODE_DOCUMENT
This operation depends on the value of the newChild parameter.
| Value | Description |
|---|---|
| NODE_ATTRIBUTE, NODE_CDATA_SECTION, NODE_DOCUMENT, NODE_ENTITY, NODE_ENTITY_REFERENCE, NODE_NOTATION, NODE_TEXT | Returns an error. These nodes are not valid as children of a document node. |
| NODE_COMMENT, NODE_PROCESSING_INSTRUCTION | Replaces the specified oldChild with the supplied newChild and returns oldChild. |
| NODE_DOCUMENT_TYPE, NODE_ELEMENT | Replaces oldChild with newChild and returns oldChild. By definition, an XML document (the document node) can have only a single child. Therefore, an error is returned if the document node already has a child. |
| NODE_DOCUMENT_FRAGMENT | Replaces the specified oldChild with the children of the document fragment (newChild) and returns oldChild. The insert operations are subject to the rules for child nodes and can fail if the document fragment children represent node types that cannot be inserted. |
| NODE_DOCUMENT_TYPE | Returns an error. The document type is read-only. |
NODE_DOCUMENT_FRAGMENT
This operation depends on the value of the newChild parameter.
| Value | Description |
|---|---|
| NODE_ATTRIBUTE, NODE_DOCUMENT, NODE_DOCUMENT_TYPE | Returns an error. These nodes types are not valid as children of a document fragment. |
| NODE_CDATA_SECTION, NODE_COMMENT, NODE_ELEMENT, NODE_ENTITY_REFERENCE, NODE_PROCESSING_INSTRUCTION, NODE_TEXT | Replaces the specified oldChild with the supplied newChild and returns oldChild. |
| NODE_DOCUMENT_FRAGMENT | Replaces the specified oldChild with the children of the document fragment (newChild) and returns oldChild. The insert operations are subject to the rules for child nodes and can fail if the document fragment children represent node types that cannot be inserted. |
| NODE_ENTITY, NODE_NOTATION | Returns an error. Entities and notations are read-only and cannot be inserted into a document. |
NODE_ELEMENT
This operation depends on the value of the newChild parameter.
| Value | Description |
|---|---|
| NODE_CDATA_SECTION, NODE_COMMENT, NODE_ELEMENT, NODE_ENTITY_REFERENCE, NODE_TEXT, NODE_PROCESSING_INSTRUCTION | Replaces the specified oldChild with newChild and returns oldChild. |
| NODE_ATTRIBUTE, NODE_DOCUMENT, NODE_DOCUMENT_TYPE, NODE_ENTITY, NODE_NOTATION | Returns an error. These node types cannot be children of an element node. |
| NODE_DOCUMENT_FRAGMENT | Replaces the specified oldChild with the children of the document fragment (newChild) and returns oldChild. The insert operations are subject to the rules for child nodes and can fail if the document fragment children represent node types that cannot be inserted. |
| NODE_ENTITY_REFERENCE | Returns an error. Although the child nodes of an entity reference are the expanded entity, the children cannot be modified. |
This method applies to the following objects and interfaces:
