xeCData
xeCData = 4
Example
function IsCDataNode(Node: TXMLNode): Boolean;
begin
Result := (Node <> nil) and (Node.ElementType = xeCData);
end;
Usage
xeCData identifies a Velox XML CDATA-section node whose literal value joins element text but is written without delimiter validation.
Additional Technical Info
xeCData identifies a parsed <![CDATA[...]]> section. NativeXML keeps the section as a distinct raw node and returns its contained text literally rather than applying the character-data entity replacement used by xeCharData.
An element's Value concatenates the values of its immediate CharData, WhiteSpace and CDATA nodes in raw order. CDATA is therefore text-like for Value, but it remains distinguishable through ElementType. Element-only child access excludes it.
Mutation and serialization quirk
The script wrapper exposes TXMLNode.Value read/write. Assigning a CDATA node replaces its literal stored content. The writer then emits:
<![CDATA[stored content]]>
It does not split or reject a stored ]]> sequence. If script mutation introduces that sequence, saving can terminate the section early and emit malformed XML. Validate or split such content before assignment.
Writing the parent element's Value is not an equivalent way to update CDATA. NativeXML's element setter raises when CDATA or other competing text-like nodes are present; mutate the intended borrowed node deliberately.
Lifetime and traversal
CDATA nodes are owned by the document. Raw traversal can return them; Elements[...] cannot. A borrowed reference is invalid after document clear, reload or destruction. The constant itself is immutable and side-effect free.
