What’s New in XML Schema 1.1?


Since the introduction of XML Schema 1.0, the standard has been widely adopted. Developers have requested several changes over the years, most notably the ability to specify and validate more granular business rules and also to allow flexible schema evolution. There are numerous changes and enhancements in the XML Schema 1.1 Recommendation aimed at addressing these issues.

Let’s take a look at the most notable new features and some resources for learning more or getting started right away with XML Schema 1.1.

Generating a Schema from Multiple XML Instances


I was recently talking with one of our Support Engineers about common questions he receives from customers. One that comes up a lot is schema generation. XMLSpy will generate a valid XSD from a DTD, a relational database structure, a JSON Schema, and of course, an XML instance.

But what many customers don’t know is that the XML editor will also create an XML Schema based on a group of related XML files – and this is a common requirement. Let’s take a look at how it works.

XML Wildcard Data Mapping and Transformation in MapForce


MapForce 2014 now supports mapping of XML wildcards that create a designed-in extension mechanism for XML Schemas, implemented as <xs:any> or <xs:anyAttribute>.

Consider this XML fragment viewed in XMLSpy:

Fragment of an XML document following the GPX XML Schema

This small portion of a very long file shows two track points recorded during a road trip by a Garmin GPS device. The XML data follows the GPX XML Schema, with Garmin extensions to add speed and course heading values. XML wildcard mapping lets you map these extensions in MapForce just like any other elements explicitly defined in the XML Schema.

Let’s assume we want to read the .gpx file and extract the highest speed recorded for a trip:

Use XPath Expressions to Refine Data Selection


In this era of big data we often need to simplify analysis and communication by creating customized views into sections of a larger file. XPath, short for XML Path Language, is designed to allow users to address parts of large XML documents. XMLSpy supports XPath with an XPath Analyzer window and in its interface for charting XML data, MapForce supports XPath functions for XML data mapping, and StyleVision supports XPath in conditional templates, extension templates, and template filtering.
