| Transforms an XML element into a JSON string representation. See http://json.org. | ||||
| <p/> | ||||
| Sample usage: | ||||
| <pre> | ||||
| xquery version "1.0-ml"; | ||||
| import module namespace json="http://marklogic.com/json" at "json.xqy"; | ||||
| json:serialize(&lt;foo&gt;&lt;bar&gt;kid&lt;/bar&gt;&lt;/foo&gt;) | ||||
| </pre> | ||||
| Sample transformations: | ||||
| <pre> | ||||
| &lt;e/&gt; becomes {"e":null} | ||||
| &lt;e&gt;text&lt;/e&gt; becomes {"e":"text"} | ||||
| &lt;e&gt;quote " escaping&lt;/e&gt; becomes {"e":"quote \" escaping"} | ||||
| &lt;e&gt;backslash \ escaping&lt;/e&gt; becomes {"e":"backslash \\ escaping"} | ||||
| &lt;e&gt;&lt;a&gt;text1&lt;/a&gt;&lt;b&gt;text2&lt;/b&gt;&lt;/e&gt; becomes {"e":{"a":"text1","b":"text2"}} | ||||
| &lt;e&gt;&lt;a&gt;text1&lt;/a&gt;&lt;a&gt;text2&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":["text1","text2"]}} | ||||
| &lt;e&gt;&lt;a array="true"&gt;text1&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":["text1"]}} | ||||
| &lt;e&gt;&lt;a type="boolean"&gt;false&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":false}} | ||||

| </pre> | ||||
| <p/> | ||||
| Namespace URIs are ignored. Namespace prefixes are included in the JSON name. | ||||
| <p/> | ||||
| Attributes are ignored, except for the special attribute @array="true" that | ||||
| indicates the JSON serialization should write the node, even if single, as an | ||||
| array, and the attribute @type that can be set to "boolean" or "number" to | ||||
| dictate the value should be written as that type (unquoted). There's also | ||||
| an @quote attribute that when set to true writes the inner content as text | ||||
| rather than as structured JSON, useful for sending some XHTML over the | ||||
| wire. | ||||
| <p/> | ||||
| Text nodes within mixed content are ignored. | ||||
| @param $x Element node to convert | ||||
| @return String holding JSON serialized representation of $x | ||||
