xeDeclaration
xeDeclaration = 6
Example
function IsXMLDeclaration(Node: TXMLNode): Boolean;
begin
Result := (Node <> nil) and (Node.ElementType = xeDeclaration);
end;
Usage
xeDeclaration identifies Velox XML's root-level XML declaration container for version, encoding and declaration attributes.
Additional Technical Info
xeDeclaration identifies the specialised <?xml ...?> declaration node. NativeXML models it as a root-level container whose attributes include values such as version and encoding; its fixed node name is xml.
TNativeXML.Root returns the first ordinary xeElement, not the declaration. Use raw FindFirst/FindNext traversal when declaration nodes matter, and check the enum before using the broad Name/Value properties.
Parser and writer behavior
The declaration parser reads an attribute list, requires the ?> terminator and specially consumes an immediately following CR/LF pair. The document records the declaration encoding for its parser/writer configuration. Saving writes <?xml, the stored attributes, ?> and the configured separator.
This kind is distinct from a generic xeInstruction and the specialised xeStylesheet. It does not represent an element named xml.
The broad script wrapper exposes Name and Value setters even though native virtual behavior varies by node kind. Declaration content should be changed through valid attributes in APIs that expose them; arbitrary Name/Value mutation is not a safe declaration editor and can raise or yield malformed output.
Borrowed declaration and attribute references are document-owned and invalid after clear, reload or free.
