How to Debug XPath and XQuery Expressions


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?


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.

XPath Editor and Tester Video


Writing XPath expressions is an important skill for any developer – whether they are for an XSLT stylesheet, complex XQuery instruction, or even selecting data in a mobile application. And while XPath syntax is simple by nature, it’s also powerful, and writing and debugging the most efficient expression to select exactly the data you need can be a challenge.

This quick video demonstrates some of the tools in the XMLSpy XPath editor that make developing and testing XPath, as well as XQuery, easier. By using a point and click interface for interactive, incremental expression building, you’ll get what you need faster and with less frustration.

Innovative New XPath/XQuery Tools


Support for XPath and XQuery in XMLSpy got a major boost with Release 3 of Version 2015. In addition to adding support for the latest standards versions – XPath 3.1 and XQuery 3.1 – we’ve added innovative new tools for developing and testing XPath and XQuery expressions in the XPath/XQuery window.

These new tools make it much faster to develop, evaluate, and refine expressions and statements before adding them to larger XSLT or XQuery documents. This will save you time and frustration – because you can understand how each operator or function works and ensure that your expressions return the desired results immediately. I found the function descriptions and entry helpers especially helpful for learning how the new maps and arrays features in XPath/XQuery 3.1 are implemented.
