Description
Indicates whether a PBDOM_ELEMENT object has one or more child objects.
Syntax
pbdom_element_name.HasChildren()
Return value
Boolean.
Returns true if this PBDOM_ELEMENT object has at least one child object and false if this PBDOM_ELEMENT object has no child objects.
Examples
The HasChildren method is invoked for elements in the following XML fragment:
<books>
<title>Inside OLE</title>
<author>Kraig Brockschmidt</author>
<site href="http://www.microsoft.com/press"/>
</books>The books element has three child elements: title, author, and site. The title and author elements each have a child PBDOM_TEXT object. The HasChildren method returns a value of true when invoked for these elements.
In contrast, the site element has a PBDOM_ATTRIBUTE href, which is not considered a child PBDOM_OBJECT. The HasChildren method returns a value of False when invoked for the site element.
Usage
PBDOM's implementation of the HasChildren method differs from JDOM's implementation in that the JDOM HasChildren method returns true only if an Element contains child Elements. Text and other types of objects do not count.
PBDOM provides an alternative method, HasChildElements, to specifically detect whether a PBDOM_ELEMENT object has at least one child PBDOM_ELEMENT object.
