Then, the automaton state sy to which the filter path is connected reacts similar to a state without an attached filter with the difference, that not for each XML node that fulfills the given node name test a token is created, but only for those XML nodes contained in the set N which fulfill the given node name test. , if tokens are transferred top-down from sy to si, we follow an idea of [10]: Whenever a token T1=(…,nv/sy) or a token T1= (nv/sy,…) that contains the state sy is generated, this token gets a reservation that depends on whether or not the filter automaton for Fi evaluates to true for the XML node nv.

G. ancestor, descendant, following and preceding) within XPath queries. ─ We have evaluated query performance on two different XML representations – one uncompressed and one compressed – that are integrated into our approach. Besides a DOM-based XML representation, we have implemented a second XML main-memory representation, that is based on Succinct compression [2] and that – if combined with an index – not only allows for an XPath evaluation as fast as the DOM-based representation, but also needs only 20% of the main memory required by a DOM representation.
