Class Element

    • The Element object represents an XML Element node and provides methods for manipulating its content, attributes, and relationships within an XML document.

    • You can add, remove, and retrieve content (including child elements and other nodes) from an Element using methods like addContent, removeContent, getAllContent, getChildren, and getContent.

    • Attributes of an Element can be accessed, set, and removed using methods like getAttribute, getAttributes, setAttribute, and removeAttribute.

    • The name and text value of an Element can be retrieved and set using getName, getQualifiedName, getText, setText, and getValue.

    • Methods are available to check the parent and document of an Element, determine if it is the root element, and detach it from its parent.
