How to find a node using expressions

If your main data source contains hundreds of nodes, how will you find one using expressions? Suppose "Nodes" is the parent node with the following xpath:
XPathNavigator nodes = this.CreateNavigator().SelectSingleNode("/my:myFields/my:Nodes", this.NamespaceManager);
To find nodes inside "Nodes" (parent node), do the following
nodes.SelectSingleNode("child::*[contains(name(),"abc")]");
This will select the child node that has "abc" in its name. This is just an example and can have many practical uses.
