There seems to be no industry standard on how to map XML Attributes to JSON Values.

But there are some commonly used conventions:

1. Converting each XML attribute to a single JSON object property. The property name is set to the attribute name and the property value is set to the attribute value. For example:

XML:
<div id="1001" class="banner"/>

JSON:
{
	"div": {
		"id": "1001",
		"class": "banner"
	}
}

2. Prefixing XML attribute name with "@". To differentiate JSON object properties converted from XML attributes from XML sub elements, "@" is added to each XML attribute name. For example:

XML:
<div id="1001" class="banner"/>

JSON:
{
	"div": {
		"@id": "1001",
		"@class": "banner"
	}
}

3. Converting empty XML attributes to JSON properties with Null values. If the value of an XML attribute is an empty string, it is converted to the JSON Null value. For example:

XML:
<div id="1001" class=""/>

JSON:
{
	"div": {
		"@id": "1001",
		"@class": null
	}
}
