158 Transforms an XML element into a JSON string representation. See http://json.org.
159 &lt;p/&gt;
160 Sample usage:
161 &lt;pre&gt;
162 xquery version &quot;1.0-ml&quot;;
163 import module namespace json=&quot;http://marklogic.com/json&quot; at &quot;json.xqy&quot;;
164 json:serialize(&amp;lt;foo&amp;gt;&amp;lt;bar&amp;gt;kid&amp;lt;/bar&amp;gt;&amp;lt;/foo&amp;gt;)
165 &lt;/pre&gt;
166 Sample transformations:
167 &lt;pre&gt;
168 &amp;lt;e/&amp;gt; becomes {&quot;e&quot;:null}
169 &amp;lt;e&amp;gt;text&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;text&quot;}
170 &amp;lt;e&amp;gt;quote &quot; escaping&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;quote \&quot; escaping&quot;}
171 &amp;lt;e&amp;gt;backslash \ escaping&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;backslash \\ escaping&quot;}
172 &amp;lt;e&amp;gt;&amp;lt;a&amp;gt;text1&amp;lt;/a&amp;gt;&amp;lt;b&amp;gt;text2&amp;lt;/b&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:&quot;text1&quot;,&quot;b&quot;:&quot;text2&quot;}}
173 &amp;lt;e&amp;gt;&amp;lt;a&amp;gt;text1&amp;lt;/a&amp;gt;&amp;lt;a&amp;gt;text2&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:[&quot;text1&quot;,&quot;text2&quot;]}}
174 &amp;lt;e&amp;gt;&amp;lt;a array=&quot;true&quot;&amp;gt;text1&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:[&quot;text1&quot;]}}
175 &amp;lt;e&amp;gt;&amp;lt;a type=&quot;boolean&quot;&amp;gt;false&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:false}}
176 &amp;lt;e&amp;gt;&amp;lt;a type=&quot;number&quot;&amp;gt;123.5&amp;lt;/a&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:{&quot;a&quot;:123.5}}
177 &amp;lt;e quote=&quot;true&quot;&amp;gt;&amp;lt;div attrib=&quot;value&quot;/&amp;gt;&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;&amp;lt;div attrib=\&quot;value\&quot;/&amp;gt;&quot;}
178 &lt;/pre&gt;
179 &lt;p/&gt;
180 Namespace URIs are ignored. Namespace prefixes are included in the JSON name.
181 &lt;p/&gt;
182 Attributes are ignored, except for the special attribute @array=&quot;true&quot; that
183 indicates the JSON serialization should write the node, even if single, as an
184 array, and the attribute @type that can be set to &quot;boolean&quot; or &quot;number&quot; to
185 dictate the value should be written as that type (unquoted). There's also
186 an @quote attribute that when set to true writes the inner content as text
187 rather than as structured JSON, useful for sending some XHTML over the
188 wire.
189 &lt;p/&gt;
190 Text nodes within mixed content are ignored.
191
192 @param $x Element node to convert
193 @return String holding JSON serialized representation of $x
