  • Course XQuery : Content

    The XML language XQuery is central to the XQuery course. The participants learn how XQuery can be used to select and transform XML data.

    XQuery Intro

    Attention is paid to the syntax of XQuery, the XQuery specification and the parts of XQuery.

    XML Vocabularies

    Also the relationships of XQuery with other XML vocabularies such as XPath, XSLT and XML Schema are discussed.

    XQuery Data Types and Expressions

    Furthermore the data types, built-in functions of XQuery and the different XQuery expressions are discussed.

    Flower Expression

    The so called flower expressions which are characteristic for XQuery are treated in detail.


    Finally attention is paid to some more advanced applications of XQuery like joins, the use of XQuery in combination with other technologies and for the accessing of relational data.

    Audience Course XQuery

    The course XQuery is designed for developers who wish to apply XQuery in practice for the selection of XML data.

    Prerequisites Course XQuery

    To participate in this course basic knowledge of XML and HTML syntax is required. Experience with programming and Structured Query Language (SQL) is beneficial for a good understanding.

    Realization Training XQuery

    The theory is discussed on the basis of presentation slides. Demos are used to clarify the theory. The theory is interspersed with hands-on exercises. Usage is made of modern XQuery tools and the course material is in English. The course times are from 9.30 up and to 16.30.

    Certification XQuery

    After successful completion of the course, participants receive an official XQuery certificate.

    Course Forms

    All our courses are classroom courses in which the students are guided through the material on the basis of an experienced trainer with in-depth material knowledge. Theory is always interspersed with exercises.


    We also do custom classes and then adjust the course content to your wishes. On request we will also discuss your practical cases.

    Course times

    The course times are from 9.30 to 16.30. But we are flexible in this. Sometimes people have to bring children to the daycare and other times are more convenient for them. In good consultation we can then agree on different course times.


    We take care of the computers on which the course can be held. The software required for the course has already been installed on these computers. You do not have to bring a laptop to participate in the course. If you prefer to work on your own laptop, you can take it with you if you wish. The required software is then installed at the start of the course.


    Our courses are generally given with Open Source software such as Eclipse, IntelliJ, Tomcat, Pycharm, Anaconda and Netbeans. You will receive the digital course material to take home after the course.


    The course includes lunch that we use in a restaurant within walking distance of the course room.


    The courses are planned at various places in the country. A course takes place at a location if at least 3 people register for that location. If there are registrations for different locations, the course will take place at our main location, Houten which is just below Utrecht. A course at our main location also takes place with 2 registrations and regularly with 1 registration. And we also do courses at the customer’s location if they appreciate that.


    At the end of each course, participants are requested to evaluate the course in terms of course content, course material, trainer and location. The evaluation form can be found at https://www.klantenvertellen.nl/reviews/1039545/spiraltrain?lang=en. The evaluations of previous participants and previous courses can also be found there.


    The intellectual property rights of the published course content, also referred to as an information sheet, belong to SpiralTrain. It is not allowed to publish the course information, the information sheet, in written or digital form without the explicit permission of SpiralTrain. The course content is to be understood as the description of the course content in sentences as well as the division of the course into modules and topics in the modules.
