XML took a basic but crucial step toward maturity today with the World Wide Web Consortium's introduction of XQL, a querying language for XML documents.

XQL has been argued as just a model for asking for specific sets of elements with very limited query capability. This paper proposes several extensions of XQL to address the issues. The extensions include full-text indexed search, path variables, joins, session-based navigations, and updates. Effort has been spent to preserve the conciseness of the language syntax.

Representatives from Microsoft, Texcel and WebMethods have submitted to the W3C a position paper that proposes using XSL as the basis for a general-purpose query language for XML documents.

XQL is a language for querying structured documents, and it is a specification of W3C. The XQL engine in <blue>XS also provides numerical and boolean functions on attributes and date-time parsing. In the near future it will also support positional conditions.

This is a preliminary look at some of the extra capabilies we can provide once all of our astronomical datasets are converted to our XML format. Although this demonstration lacks a refined interface, it shows that the addition of XML tags can allow quite specific queries to be constructed.

XQL (XML Query Language) is a way to locate and filter the elements (data fields) and text in an Extensible Markup Language (XML) document. XML files are used to transmit collections of data between computers on the Web. XQL provides a tool for finding and/or selecting out specific items in the data collection in an XML file or set of files.

XML is highly suited to representing richly structured information such as dictionary content, and conversely this well-structured storage of the information enables innovative browsing interfaces. We demonstrated this previously with the development of Kirrkirr, a web-based application that allows users to interactively explore a Warlpiri (a Central Australian language) dictionary in XML format.

We consider the recently proposed XQL language, which is designed to query XML documents by content and structure. We show that an already existing model, namely ``Proximal Nodes??, is the only one that addresses all the complex querying operations defined by XQL and that suggests an efficient implementation for them.

The XQL (XML Query Language) is a notation designed to address XML documents just as SQL is used to access relational databases. XQL Query Engine release 1.1(XQE1.1) is a JAVA 1.2 compliant API package that implements the XQL specifications for XML document addressing. It offers the capabilities of processing XQL query statements, accessing entities contained in XML documents and return results to calling applications.

We believe that XML query languages can dramatically increase the utility of XML documents by providing powerful and convenient access to the information they contain. As more and more of our critical data is stored in XML documents, presented as XML documents through middleware, or made accessible via XML-oriented APIs, the ability to query XML documents becomes an essential aspect of being able to use the information we have. XQL is a query language based on the structure of XML documents. It is simple, easy to implement, and powerful. This paper explores scenarios in which XML queries might be performed, and presents a tutorial for the XQL query language.

Today, XML is used in three different ways. First, XML is used as a markup language, where documents are considered to be trees (with the occasional hyper link added) which represent the document structure. Secondly, XML is used as an interchange format for structured data. Here, a document is considered as a set of fields, each of which has a specific data type. The third aspect is to use XML to represent text, where a document consists of words which can be stemmed and phrases and the like.

This document describes basic the features of the XML Query Language (XQL.) A proposal for the XML Query Language (XQL) specification was submitted to the XSL Working Group in September 1998. The spec can be found at http://www.w3.org/TandS/QL/QL98/pp/xql.html. Since it is only a proposal at this point, things may change, but it is very likely that the final version will be close to the proposal. Most of this document was copied straight from the spec.

The GMD-IPSI XQL engine is a Java implementation of the W3C-QL'98 workshop paper syntax of XQL, based on a persistent thread-safe DOM implementation. The PDOM can be built from XML documents using a SAX 1.0 parser.

The XML Query Language proposal (XQL), jointly developed by Texcel, webMethods, and Microsoft, proposes a query language for XML documents. This document complements the proposal by describing XQL's underlying design and the motivation for that design.

This tutorial discusses the simplest XQL queries, which are also likely to be the most common. In this tutorial, we will present a quick overview of XQL without taking the time to be precise.

As more and more information is either stored in XML, exchanged in XML, or presented as XML through various interfaces, the ability to intelligently query our XML data sources becomes increasingly important. XML documents are structured documents – they blur the distinction between data and documents, allowing documents to be treated as data sources, and traditional data sources to be treated as documents.
