XmlGetChildNodes Function

Action

XmlGetChildNodes returns a handle to a list of nodes (nodelist) that contains all child handles of the passed node/document handle. To access a node in the nodelist you have to use XmlGetItem. To determine the number of nodes in the nodelist, use XmlGetCount. If you call this method on an element node with a text value the function will return 1 because the text value itself is a child node of type text.

If you want to access a specific child node, you can also call XmlGetChildByIndex to get a direct reference to a child node.
