XML templates

xml values can be constructed using an XML template expression. Phase 2 processing for xml template tag parses strings using the XML 1.0 Recommendation’s grammar for content (what XML allows between a start-tag and an end-tag). Interpolated expressions can be in content (xml or string values) or in attribute values (string values).

 
import ballerina/io;

string url = "https://ballerina.io";

xml content = 

    xml `<a href="${url}">Ballerina</a> is an <em>exciting</em> new language!`;

xml values can be constructed using an XML template expression. Attribute values can have string values as interpolated expressions.

xml p = xml `<p>${content}</p>`;

Interpolated expressions can also be in content (xml or string values).

public function main() {
    io:println(content);
    io:println(p);
}
