The XML node in Node-RED is a node that can be used to parse and generate XML data.

The XML node will parse the input to JSON when the input is recognized as XML. When it's formatted as JSON, the node will output XML. This allows bi-directional convertion of XML and JSON data, which can be useful for integrating with other systems and services that only support one of these formats.

The XML core node has generally 2 use-cases:

  • Parsing and extracting XML data: The XML node can be used to parse XML data and extract specific elements and attributes. This can be useful for tasks such as reading data from XML files, parsing XML messages from devices, or extracting data from XML (usually SOAP) APIs.
  • Generating XML data: The XML node can be used to generate XML data from scratch. This can be useful for tasks such as creating XML files, generating XML messages to send to devices, or creating XML documents to be consumed by other systems and services.

As the node can construct and deconstruct, the modification of XML is an implicit capability.


Parsing XML data

Providing the following data in the XML node:

<?xml version="1.0" encoding="UTF-8"?>

The XML node parses the XML data and converts it to JSON.

"weatherdata": {
"current": {
"temperature": 25.5,
"humidity": 65,
"wind": 10

Node Documentation

Converts between an XML string and its JavaScript object representation, in either direction.


payloadobject | string
A JavaScript object or XML string.
options object
This optional property can be used to pass in any of the options supported by the underlying library used to convert to and from XML. See the xml2js docs for more information.


payloadobject | string
  • If the input is a string it tries to parse it as XML and creates a JavaScript object.
  • If the input is a JavaScript object it tries to build an XML string.


When converting between XML and an object, any XML attributes are added as a property named $ by default. Any text content is added as a property named _. These property names can be specified in the node configuration.

For example, the following XML will be converted as shown:

<p class="tag">Hello World</p>
  "p": {
    "$": {
      "class": "tag"
    "_": "Hello World"
