Document.createCDATASection()
createCDATASection()
creates a new CDATA section node, and returns it.
Syntax
JavaScript
Copy Code
<var>CDATASectionNode</var> = document.createCDATASection(data)
CDATASectionNode
is a CDATA Section node.data
is a string containing the data to be added to the CDATA Section.
Example
JavaScript
Copy Code
var docu = new DOMParser().parseFromString('<xml></xml>', "application/xml") var cdata = docu.createCDATASection('Some <CDATA> data & then some'); docu.getElementsByTagName('xml')[0].appendChild(cdata); alert(new XMLSerializer().serializeToString(docu)); // Displays: <xml><![CDATA[Some <CDATA> data & then some]]></xml>
Notes
- This will only work with XML, not HTML documents (as HTML documents do not support CDATA sections); attempting it on an HTML document will throw
NOT_SUPPORTED_ERR
. - Will throw a
NS_ERROR_DOM_INVALID_CHARACTER_ERR
exception if one tries to submit the closing CDATA sequence ("]]>") as part of the data, so unescaped user-provided data cannot be safely used without with this method getting this exception (createTextNode()
can often be used in its place).
