XmlGetItem Function

Action

XmlGetItem returns a node from the nodelist. The nodes are identified by their index in the list beginning with 0 for the first. Use XmlGetCount to determine the number of nodes in the nodelist. You can iterate through the nodes in the nodelist by accessing the nodes from index 0 to XmlGetCount - 1.

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