XML Processing Made Easy with Ballerina

XML Processing Made Easy with Ballerina. Let's take a look at a modern approach in handling XML as a built-in functionality in a programming language.


The Ballerina programming language contains built-in support for XML data. It supports defining, validating, and manipulating XML directly from the language syntax itself. In this article, we will go through its features, and how to use it effectively.

Creating and Manipulating XML

The first approach when defining an XML value in Ballerina is to use direct literals. 

The XML value above is created using the XML literal syntax. In this way, the compiler identifies this specifically as an XML value and validates the literal value given by the user. So if we have mistakes in the XML value, such as mismatching start/end tags, you will be immediately given an error at compile-time, and of course, it will be highlighted as an invalid value in the IDE. 

An XML value in Ballerina is structured as a sequence of singleton XML values. These singletons are XML elements, processing instructions, comments, and text. The following example shows how to create a single XML value by combining two XML elements.
