[2005-07-30 00:09 UTC] ja dot doma at gmail dot com

Description:
------------
This code:

require_once "XML/Util.php";

// creating an XML tag
$tag = XML_Util::createTag("test", array(), "Content ]]></test> here!",null, XML_UTIL_CDATA_SECTION);

Will result in:

<test><![CDATA[Content ]]></test> here!]]></test>

As you can see it is wrong bechavior. I'm not sure, but the only one solution is to create two CDATA sections there:

<test><![CDATA[Content ]]>]]><![CDATA[</test> here!]]></test>

Note: the ]]> sequence is outside CDATA sections

Normal(DOM) parser may merge sequence of CDATA and text into one DomNode.text field.

Sorry for my badly english =)

Test script:
---------------
require_once "XML/Util.php";

// creating an XML tag
$tag = XML_Util::createTag("test", array(), "Content ]]></test> here!",null, XML_UTIL_CDATA_SECTION);
echo $tag;

Expected result:
----------------
<test><![CDATA[Content ]]>]]><![CDATA[</test> here!]]></test>

Actual result:
--------------
<test><![CDATA[Content ]]></test> here!]]></test>

The solution might be(line 642):

function createCDataSection($data) {
return sprintf("<![CDATA[%s]]>", preg_replace('/\]\]>/', "]]>]]><![CDATA[", strval($data)));
}

Oops! Since XML can not contain > symbol it must be escaped with >

So the proper fix to bug is:

function createCDataSection($data)
{
return sprintf("<![CDATA[%s]]>", preg_replace('/\]\]>/', "]]>]]><![CDATA[", strval($data)));
}
