xml method Null safety

void xml(
  1. String input,
  2. {XmlEntityMapping? entityMapping}

Adds a raw XML string. The string will be parsed as XmlDocumentFragment and throws an XmlParserException if the input is invalid.

To generate a bookshelf element with two predefined book elements, one would write:

builder.element('bookshelf', nest: () {
  builder.xml('<book><title>Growing a Language</title></book>');
  builder.xml('<book><title>Learning XML</title></book>');


void xml(String input, {XmlEntityMapping? entityMapping}) {
  final fragment =
      XmlDocumentFragment.parse(input, entityMapping: entityMapping);
