CustomXMLNode.HasChildNodes Method - PowerPoint

Gets True if the current element node has child element nodes.

Note
References to DTDs from custom XML parts are not supported. DTD references in custom XML parts will not resolve, and custom XML parts containing DTD references generate an exception when an attempt is made to save the file's content to a flat XML file.

Syntax

expression.HasChildNodes

expression An expression that returns a CustomXMLNode object.

Return Value
Boolean

Remarks

This method will always return False when CustomXMLNode isn't of node type msoCustomXMLNodeElement.

Example
The following example demonstrates using various methods to add custom XML parts, select parts and nodes with different criteria, append child subtrees, tests whether the subtree was successfully added, and delete parts and nodes.
