item(index[, subindex]) Returns a single object or collection of objects corresponding to the element matching the index value (or, optionally, the index and subindex values).
Returned Value One object or collection (array) of objects. If there are no matches to the parameters, the returned value is null.
Parameters
index | When the parameter is a zero-based integer, the returned value is a single element corresponding to the said numbered item in source code order (nested within the current element); when the parameter is a string, the returned value is a collection of elements whose id or name properties match that string.
subindex | If you specify a string value for the first parameter, you may use the second parameter to specify a zero-based integer to retrieve a specific element from the collection whose id or name properties match the first parameter's string value.
