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
