| 摘 要： | 目前大部分前缀编码方案都不能很好的支持XML文档的数据更新.提出的前缀编码方案不仅能高效地支持结构查询,快速准确的判断XML文档结构树中任意两个结点之间的父子、先后代以及兄弟关系,而且对插入的结点采用新的编码规则,避免了更新操作带来的编码调整问题,能有效支持XML文档更新.

| Abstract: | Most prefix-labeling scheme nowadays cannot support XML document updating fully. Based on the comparison of the current prefix-labeling scheme, a novel prefix-labeling was proposed. This scheme does not only efficiently support structure queries, which can rapidly and accurately judge the parent-child, ancestor-descent and sibling relationships between any two nodes of the XML document tree, it also adopts the new labeling rules to avoid an update coding adjustment operation that may bring about when new nodes are inserted, and effectively support update for XML document. |
