Implementing Basic Filtering in Your App


There are numerous ways to implement searching and filtering within mobile apps.  MobileTogether Designer allows developers to perform filtering on either your mobile app or on the server via a SQL query.  Knowledge of each of these methods, along with the use cases for them, is an essential tool every mobile developer should possess.

This video tutorial continues to build out the books database project that has been constructed in previous tutorials.  It will cover the steps needed to implement basic filtering in your mobile app.  Additionally, it also introduces developers to the usage of user defined XQuery functions which provide a method to centralize application logic.

How to Debug XSLT and XQuery


Nothing’s more frustrating than getting unintended results from an XSLT or XQuery transformation and having to spend hours tracking down the issue – especially if you’ve inherited the project from another developer or haven’t looked at the code in a few months.  Of course, XMLSpy has long included an XSLT debugger and XQuery debugger for setting break points and stepping through transformations to identify problems.

For a more interactive debugging process, XMLSpy also includes XSLT/XQuery back-mapping.

With back-mapping enabled, you can simply click on or hover over the portion of your output document you want to zero in on, and XMLSpy will immediately highlight the source XML and XSLT or XQuery instruction that is responsible. Let’s see how it works.
