Abstract
In this paper, the focus is on accelerating XPath location steps for evaluating regular path expression with predicate parameter in particular since it is a core component of many XML processing standards such as XSLT or XQuery. We present a new indexing structure, namely Xp-tree, which is used to speed-up the evaluation of XPath. Based on accelerating a node using planar combined with the numbering scheme, we devise efficiently derivative algorithms. Our experimental results demonstrate that the proposed method outperforms previous approaches using R-tree indexing mechanism in processing XML queries.
Keywords
- Leaf Node
- Child Node
- XPath Query
- Context Node
- Sibling Node
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
