.... With the growing importance of XML in data exchange, much research has been done in providing flexible query mechanisms to extract data from XML documents [69, 72, 71, 68, 67, 70] We propose a novel index structure that addresses a wide range of challenges in indexing semi structured data [73]. Unlike state of the art approaches that disassemble a structured query into multiple sub queries, and then join the results of these sub queries to provide the final answers, our method uses tree structures as the basic unit of query to avoid expensive join operations. XML provides a flexible ....
....(Symbol, Prefix) where symbol encodes the node and prefix is the path from the root node. We also convert XML queries to sequences. Most structural XML queries can be performed through (non contiguous) subsequence matching. The only exception occurs when a branch has multiple identical child nodes [73]. The benefits of modeling XML queries through sequence matching is that structural queries can be processed as a whole instead of being broken down to smaller query units (paths or nodes of XML document trees) For example, Figure 2 is a sequential representation of the purchase record, where the ....
