Build XML from JSON
XML Builder was the part of fast-xml-parser for years. But considering that any bug in parser may false-alarm the users who are only using builder, we have decided to split it into a separate package.
npm install fast-xml-builder
import XMLBuilder from 'fast-xml-builder';
const builder = new XMLBuilder();
const xml = builder.build({ name: 'value' });
fast-xml-builder fully support the response generated by fast-xml-parser. So you can use the maximum options as you are using for fast-xml-parser like preserveOrder, ignoreAttributes, attributeNamePrefix, textNodeName, cdataTagName, cdataPositionChar, format, indentBy, suppressEmptyNode and many more. Any change in parser will reflect here time to time.
