bool XmlResults::previous(XmlValue &value);
bool XmlResults::previous(XmlDocument &document);

Retrieves the previous value in the result set. When the first value in the results set has been reached, the XmlResults::previous method returns false. For an eager results set, the iterator logically points "between" adjacent entries which means that alternating calls to previous() and next() will return the same value.

This method can only be used on eagerly evaulated result sets.

Two forms of this method exist: one that places the previous value in an XmlValue object, and another that places the previous value in an XmlDocument object.
