Abstract:
Regular tree queries (RTQs) are a class of queries considered especially\\ relevant for the expressiveness and evaluation of XML query languages. \\The algorithms proposed so far for evaluating queries online, while scanning the\\ input data rather than by explicitly building the tree representation of the\\ input beforehand, only cover restricted subsets of RTQs. In contrast, we\\ introduce here an efficient algorithm for the online evaluation of\\ unrestricted RTQs. We prove our algorithm is o...     »
