Calling insertBefore on Attributes
If the current node is an attribute, calling insertBefore has the following results, depending on the value of the newChild parameter.

|---|---|
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 |
Inserts the children of the document fragment (newChild) and returns newChild. |
NODE_ENTITY_REFERENCE, NODE_TEXT |
Inserts newChild and returns newChild. |
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. |
Remarks
If an entity reference is added to an attribute, the namespace and the prefix of the entity reference are added to the element containing the attribute.
