148 Transforms an XML element into a JSON string representation. See http://json.org.
149 <p/>
150 Sample usage:
151 <pre>
152 xquery version "1.0-ml";
153 import module namespace json="http://marklogic.com/json" at "json.xqy";
154 json:serialize(&lt;foo&gt;&lt;bar&gt;kid&lt;/bar&gt;&lt;/foo&gt;)
155 </pre>
156 Sample transformations:
157 <pre>
158 &lt;e/&gt; becomes {"e":null}
159 &lt;e&gt;text&lt;/e&gt; becomes {"e":"text"}
160 &lt;e&gt;quote " escaping&lt;/e&gt; becomes {"e":"quote \" escaping"}
161 &lt;e&gt;backslash \ escaping&lt;/e&gt; becomes {"e":"backslash \\ escaping"}
162 &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"}}
163 &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"]}}
164 &lt;e&gt;&lt;a array="true"&gt;text1&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":["text1"]}}
165 &lt;e&gt;&lt;a type="boolean"&gt;false&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":false}}
166 &lt;e&gt;&lt;a type="number"&gt;123.5&lt;/a&gt;&lt;/e&gt; becomes {"e":{"a":123.5}}
167 &lt;e quote="true"&gt;&lt;div attrib="value"/&gt;&lt;/e&gt; becomes {"e":"&lt;div attrib=\"value\"/&gt;"}
168 </pre>
169 <p/>
170 Namespace URIs are ignored. Namespace prefixes are included in the JSON name.
171 <p/>
172 Attributes are ignored, except for the special attribute @array="true" that
173 indicates the JSON serialization should write the node, even if single, as an
174 array, and the attribute @type that can be set to "boolean" or "number" to
175 dictate the value should be written as that type (unquoted). There's also
176 an @quote attribute that when set to true writes the inner content as text
177 rather than as structured JSON, useful for sending some XHTML over the
178 wire.
179 <p/>
180 Text nodes within mixed content are ignored.
