With the proliferation of XML data on the internet, there is a large demand for efficient techniques in XML structural matching. We propose a novel filtering method, which is based on two auxiliary bitmaps named suffix bitmap and prefix bitmap, to accelerate XML structural matching. For each node in the XML document, the suffix bitmap captures in a compact format the tag name list of suffix subtree,...
With the rapidly increasing popularity of XML as a data format, there is a large demand for efficient XML structural matching techniques. Normally, data in XML are stored in a tree-like structure where nodes (with data) are located using the path relations in the tree.
