You can use the IHTMLElementCollection::length property to determine the number of element objects in the collection, and item or IHTMLElementCollection::tags to get individual objects or collections of objects from the collection. You can get individual objects by specifying the object's index or by using the object's name property. Index values can be numbers or names. Number values are zero-based, that is, zero for the first element object, one for the next element object, and so on. A name is valid only if it is defined by a name or IHTMLElement::id for at least one of the elements in the collection. If the name is defined by more than one element, you can use the name to get a collection of all element objects that define that name.
