Description

XML Plugin is a plugin for the 4th Dimension programming language that allows you to read and write XML documents in a more easy way. It goes far beyond the built-in XML commands of 4D.

There are several ways to access and interact with XML data. XML Plugin uses the Document Object Model (DOM), meaning the XML data is parsed into a tree object that can be navigated in an interactive way. It also allows you to modify an existing document or to create a new document from scratch and save it back to disk. The plugin takes care of all the formatting issues involved for creating well-formed XML files, so you don’t have to.

XML Plugin also allows you transform XML documents using stylesheets. XSL stands for eXtensible Style Language. XSL is a language that allows you to extract information from an XML document and re-order the output to a new format. This process is called Transforming which explains the letter T.

XSL allows you to separate content and layout from each other. The XML document holds the content in a structured format. The stylesheet specifies how to present this information. XSL is mostly used for cross-media publishing, where the same information has to be output to different kinds of media. The best known example is a newspaper that wants to publish its stories in a printed format, on the website and on small electronic devices like organizers or mobile phones. Because each output medium has its specific characteristics, it’s important to re-use the same data and format it to the particular needs of the output medium.

Differences with the built-in XML commands

Starting with 4D 2003, 4D offers some built-in commands for dealing with XML. Where 4D 2003 only contains commands for reading an XML document, 4D 2004 offers commands for both reading and writing. XML Plugin offers a more complete set of commands with more advanced features. And according to some developers, it is easier to use.

Here is a list of the features you won’t find in the built-in commands:

  • More powerful navigation commands that make it easier to find the data you are looking for.
  • Apply a 4D method against a DOM tree, so you don’t have to write recursive code to traverse the DOM tree yourself.
  • Full support for XPath (not just a subset) that allow you to query XML documents as if it were a database.
  • The XML Reader and XML Writer commands can be used to work with multiple XML documents simultaneously.
  • The XML Reader commands supports validation against a DTD.
  • The XML Writer commands handle encoding of special characters automatically.
  • Support for namespaces and XInclude.
  • Support for various schema techniques (DTD, XML Schema, Relax NG and Schematron).
  • Support for GZip compressed XML (both for reading and writing).
  • Various parsing options that give you more control on white-space handling, allow you to disable DTD validation and substitution of entity references.
  • Save fragments of an XML document (snippets).
  • Validate a created or modified document against a schema definition.
  • Support for a callback method that loads external resources such as DTDs from the database instead of the internet.
  • Support for node types such as comments, processing instructions and DTDs.
  • Ability to insert nodes before, after or as a child of another node.
  • Copy nodes or complete node trees from one document to another.
  • Get the line number of a node in the source document, which makes it easier to debug/inspect XML documents.
  • Descriptive error messages telling you what is wrong with your code or the XML document.

Licensing & pricing

XML Plugin has a very simple licensing scheme:
