Description
Returns the value of a specified child node.
GetChildValue is the read implementation of the ChildValues property.
IndexOrName identifies the desired child node by either its interface, or by a string that is the local name of the child node.
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, reading the child's value causes an exception. |
|
ntText |

|
ntCData |
The content of the CDATA section. |
|
ntEntityRef |
nil (Delphi) or NULL (C++) |
|
ntProcessingInstr |

ntComment |
The value (text) of the comment. |
