XML to JSON Simple component

The XML to JSON Simple component allows you to convert XML files into JSON files.

Configuration

The XML to JSON Simple component has the following basic configuration options:

Keep strings?

By default, the component tries to infer the type of each value and converts it into a string, number, or boolean. When this option is set to Yes, all values are transformed into strings, encapsulated in double quotes ("value").

Options

Yes
No (default)

combination with 'Has types?'

When used in combination with Has types? set to Yes, all values will be treated as strings, except for those explicitly modified using type attributes.

Using XML to JSON Simple

XML attributes

XML attributes are converted into an object as key-value pairs. Each attribute's name becomes a key, prefixed with an @ (at) symbol to indicate it was originally an XML attribute. The value of the key is the attribute's original value. Additionally, the object includes the original XML node value in a key named jsonContent.
