Research shows that the current relational database technology often inefficient when deal with the regular path expression.
研究表明,当前的关系数据库技术在处理规则路径表示的查询时通常效率不高。
XML query includes content query and structural query. The query condition can be represented as a simple path expression (SPE) or a regular path expression (RPE).
XML查询包含内容查询和结构查询,其查询条件可表示为简单路径表达式(SPE)和正则路径路径表达式(RPE)。
At first, an algorithm is proposed, which rewrites a regular path expression based XML query as a group of simple path expression based queries using mapping information (mapping graph).
首先提出了一个利用映射信息(映射图)将带正则路径表达式的XML查询重写为一组简单路径查询的算法。
If a match is found, a regular expression replace is performed on the requested path with the value of the SendTo property.
如果找到了匹配的规则,将在具有sendto属性值的被请求路径上执行正则表达式替换。
Conversely, Django USES a separate regular expression-based configuration file to map URLs to the underlying code, decoupling the URL path structure from the actual implementation.
反之,Django使用了一个单独的基于正则表达式的配置文件将URL映射为底层代码,这样就降低了URL路径结构与实际实现之间的耦合程度。
