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.

Learn About XQuery Update Facility


XQuery Update Facility is an extension of the XQuery language that allows you to make changes in an XML instance using “update expressions” that insert, delete, replace, or rename nodes. This extension provides a convenient way to make intelligent updates to XML documents, and XMLSpy has a unique implementation that makes it even easier. Let’s see how it works.

How to Speed Up Your XSLT – Automatically


Once you’ve written XSLT code to produce HTML or some other output, optimizing it to deliver the fastest execution is tricky business. Even with the powerful XSLT profiler in XMLSpy, a developer is required to have expert-level XSLT skills to test and fix the bottlenecks that the XSLT profiler identifies. Is the problem in an XPath expression? Is it an XSLT instruction? This can be a frustrating and time consuming task.

To help alleviate this issue and bring the power of XSLT to developers of all skill levels, XMLSpy also includes the XSL Speed Optimizer, which provides fixes to remove bottlenecks automatically, to immediately speed up your XSLT execution – it’s a revolutionary approach to optimizing XSLT performance.

The Only JSON Dev Tool You’ll Need


While XMLSpy might not be the first tool developers think of when they’ve got a JSON development task, XMLSpy includes comprehensive support for working with JSON, JSON Schema, and related technologies.

Over the past few product releases, we’ve added intelligent functionality for editing and converting JSON and JSON5 data to the product. We’ve completed the circle with one-click conversion between XML Schemas and JSON Schemas, as well as sample instance generation and JSON Schema documentation generation. And, most recently, we’ve added support for processing JSON with XSLT,  XPath, and XQuery.

Let’s walk through some common examples demonstrating this functionality – and see how these time-saving tools make XMLSpy the only JSON development tool you’ll need.

The Importance of Choosing Certified XBRL Tools 


Aside from complying with filing regulations, there are numerous benefits associated with adoption of the eXtensible Business Reporting Language. Standardizing information allows data validation as well as simplified comparison of reported data within an organization – from quarter to quarter or year to year, for instance – as well as comparing performance among multiple companies.

Of course, the benefits promised by XBRL  can only be realized through strict standards conformance in the tools organizations use for validating, reporting, and analyzing their XBRL data. Problems have arisen due to lack of consistent interoperability between software tools as well as less stringent validation checks that result in filing errors and diminished data quality.

Altova has always striven to deliver the closest possible conformance with supported XBRL standards and is honored to have received certification from multiple XBRL standards bodies, ensuring conformance and interoperability. Let’s take a look at the specifics and why this is so important for customers.
