TXMLNode.GetChildValue Method

Returns the value of a specified child node.

Pascal

function GetChildValue(const IndexOrName: OleVariant): OleVariant;

C++

__fastcall OleVariant GetChildValue(const OleVariant IndexOrName);

Description

Use the TXMLNode object's IXMLNode interface to call the protected GetChildValue method. GetChildValue returns the value of the node.

IndexOrName identifies the desired child node by either its interface, or by a string that is the local name of the child node.

If IndexOrName does not identify a child of this node, GetChildValue nil (Delphi) or NULL (C++). Otherwise, the return value depends on the type of the child node, as indicated in the following table:

NodeType	Value
ntAttribute	The attribute value
ntElement	If the element contains only text, this is that text value. Otherwise, GetChildValue raises an exception.
ntText	The text
ntCData	The content of the CDATA section.
ntEntityRef	nil (Delphi) or NULL (C++)
ntProcessingInstr	The content of the processing instruction except for the target.
ntComment	The value (text) of the comment.
ntDocFragment	nil (Delphi) or NULL (C++)

Note: Attributes are not considered child nodes of a node. To get the values of this node's attributes, use the GetAttribute method instead.
