- 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}}
- &lt;e&gt;&lt;a type="number"&gt;123.5&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":123.5}}
- &lt;e quote="true"&gt;&lt;div attrib="value"/&gt;&lt;/e&gt; becomes {"e":"&lt;div attrib=\"value\"/&gt;"}
- </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

- @version 1.0.1

- Ported to xquery 1.0-ml; double escaped backslashes in json:escape
- :)
- declare function json:serialize($x as element()) as xs:string {
- string-join(('{', json:print-name-value($x), '}'), "")
- };
