The impulsive headway in the use of XML attracted researchers to conduct researches on the optimization techniques of XML data management. One of the aspects that have been a challenge since then is the effective processing of user queries. Although many techniques have been proposed in the past, these techniques still suffer from large overhead due to buffering irrelevant results before producing the final output. Thus, in this paper, we propose a path query processing technique, DGReLab+, which evaluates queries without buffering irrelevant results. The evaluations revealed that DGReLab+ outperformed two other techniques which are TwigStack and QTwig.
