Translating XML Update Language into SQL

Translating XML Update Language into SQL

Several techniques for translating XML query languages into SQL have been proposed, but no work to date translates XML update languages into SQL since XQuery has not provided any update statements. However, there is a suggestion from W3C indicating that an update version of XQuery will be proposed in the near future. Furthermore, one major advantage of updating XML documents via a relational da...

Translating WFS Query to SQL/XML Query

The purpose of the WFS specification, proposed by the the OpenGIS Consortium (OGC), is to describe the manipulation operations over geospatial data using GML. Web servers providing WFS service are called WFS Servers. WFS servers publish GML views of geographic features stored in data sources such that the user can query and update data sources through a user defined feature type schema. In this...

XML-RL Update Language

Supporting for updating XML documents has recently attracted interest. This paper presents a novel declarative XML update language, which is an extension of the XML-RL query language. We define XML-RL update syntax and a set of primitive update operations to fully evolve XML into universal data representation and sharing format.

Recursive SQL-like Query language for XML

XML data are data which are not constrained by a schema, XML is fast emerging as a standard for data representation and exchange on the Word Wide Web, the ability to intelligently query XML data becomes increasingly important. In this paper we propose a recursive query language XRQL for querying and restructuring XML data. The expressive power of XRQL is comparable to Fixpoint. XRQL language is...
