Using these names we can create unique identifiers for the components of a schema. These query languages do not apply immediately to XML, because the XML data differs from traditional relational or object-oriented data. One of XML's benefits is its simplicity. Some people can do amazing things with XML, and some jobs don't require anything more complicated than XML's structured syntax. We let i range over namespaces and the "non-namespace" where items not in a namespace reside and j range over local names. Throughout this document we use the term data as in database or in electronic data interchange, and not as in XML Data. To query such a structure, XML-QL provides regular path expressions, which can specify element paths of arbitrary depth. This query matches only those persons whose addresses are in the US namespace. This simplicity allows users to produce XML data with complex structure without having to first define a schema. Of course, the key is always finding the right tool for the job. Abiteboul and D. Add My Comment. A regular path expression is permitted wherever XML permits an element. Update the OLX to use any additional elements and attributes in your problem. Need to explain what a nameset is.
This choice simplifies the data model, the query language, and allows order-independent optimizations in the query processor. For more information, see Defining Settings for Problem Components.
For example the following query constructs two disinct parts: articles and books. I am speaking largely from a developers standpoint, but I can say that the shift away from XML in software development is a strong one.
If there is a problem at runtime, I want the code and the configuration at my fingertips, not in separate documents in separate formats of expression. They must start with a letter, which can be followed by letters, numbers and underscores.
