EquiX --一种用于XML的搜索和查询语言

EquiX--A Search and Query Language for XML

Sara Cohen, Yaron Kanza, Yakov Kogan, Werner Nutt, Yehoshua Sagiv, Alexander Serebrenik

摘要:

EquiX是一种XML搜索语言,它结合了查询的强大功能和搜索的简单性。这些语言的要求进行了讨论,它表明EquiX符合必要的标准。一个基于图的抽象语法和一个正式的具体语法的EquiX查询。此外,语义的定义和评估算法。该算法在组合复杂度下是多项式的。EquiX结合了模式匹配、量化和逻辑表达式来查询XML文档的数据和元数据。EquiX中的查询结果是一组XML文档。描述结果文档的DTD将自动从查询中派生出来。

英文摘要:

EquiX is a search language for XML that combines the power of querying with the simplicity of searching. Requirements for such languages are discussed and it is shown that EquiX meets the necessary criteria. Both a graph-based abstract syntax and a formal concrete syntax are presented for EquiX queries. In addition, the semantics is defined and an evaluation algorithm is presented. The evaluation algorithm is polynomial under combined complexity. EquiX combines pattern matching, quantification and logical expressions to query both the data and meta-data of XML documents. The result of a query in EquiX is a set of XML documents. A DTD describing the result documents is derived automatically from the query.
