ET cannot output CData containing "]]>"

[garthk]

To reproduce with 0.1.6:

var et = require('elementtree'),
    root = et.Element('root'),
    cruelty = '<![CDATA[x]]>';
root.append(et.CData(cruelty));
console.log(et.tostring(root));

Buggy output:

<?xml version='1.0' encoding='utf-8'?>
<root><![CDATA[<![CDATA[x]]>]]></root>

xmllint complaint:

foo:2: parser error : Sequence ']]>' not allowed in content
<root><![CDATA[<![CDATA[x]]>]]></root>

Workaround:

root.append(et.CData(cruelty.replace(']]>', ']]]]><![CDATA[>'));

Output of workaround:

<?xml version='1.0' encoding='utf-8'?>
<root><![CDATA[<![CDATA[x]]]]><![CDATA[>]]></root>

If you use the workaround, I'd edit your package.json to lock elementtree at 0.1.6 by removing the ~ before 0.1.6:

"dependencies": {
  "elementtree": "0.1.6"
}
