XPath & XQuery Tutorial for SQL Pros (Video)

August 4, 2021/in SQL, XPath, XQuery /by Ty Shuff

Prior to starting at Altova I had zero experience with both XPath and XQuery. The first task I was presented with was to train myself on both query languages as quickly as possible and produce a concise video that would serve as an XPath tutorial and XQuery tutorial. It was important to develop a thorough understanding of their features and capabilities because both languages are integral to app development in MobileTogether and querying data in XMLSpy. I started with a strong background in SQL, learning XPath and XQuery by building queries first in SQL, and then determining how to replicate them in both query languages.

Data Mapping with XSLT3 Math Functions

April 14, 2021/in Data Integration, XPath, XQuery /by David McGahey

XSLT3 adds trigonometry and other advanced math functions, new formatting functions, functions to collect environment variables, and more, extending XSLT and XSLT2 XML transformation standards. Data analysts and other data professionals can apply XSLT3 functions to solve XML data mapping and integration challenges that require complex mathematical computations. Let’s look at some MapForce examples of data mapping with XSLT3 math functions using trigonometry and other complex math expressions.

Altova StyleVision is a unique, easy-to-use tool for creating business reports using a drag-and-drop visual design interface.

How to Debug XPath and XQuery Expressions

February 22, 2016/in Development, XPath, XQuery /by Erin Cavanaugh

XPath and XQuery are powerful functional programming languages for selecting and querying data in desktop or mobile applications – and, in fact, XQuery was added to the TIOBE Index in early 2016.

When you’re writing XPath and XQuery statements, it’s vital to ensure your expressions return the desired results, and this can be a frustrating process of trial and error. The XPath / XQuery Debugger in XMLSpy makes it easy to test and troubleshoot your code, in the very same window where you’re developing your expressions.

Is it just a wrapper around HTML5 and JavaScript?

December 14, 2015/in Applications, Mobile, Software, Technology, XPath, XQuery /by Alexander Falk

When we demonstrate MobileTogether at tradeshows, we often get asked this question: “So is it just a native app wrapper around HTML5 and JavaScript?” The simple answer is: “No.”

MobileTogether is a complete mobile app development framework that is based on our very own rendering and processing engine, which gives us a lot more flexibility and power to provide a true native app experience on each mobile operating system platform and also make important mobile platform functions that are not commonly accessible from JavaScript or HTML5-based web apps available to the developer.
