Legally use CDATA in XML

I have an XML file which XML parser choke on. A part of it is :

<closedDeal><customer><![CDATA[ABC ]]></customer></closedDeal>

The error I got is

The literal string ']]>' is not allowed in element content. Error processing resource

What i开发者_StackOverflows the correct way of using CDATA? I need CDATA because the data is read from Excel, and could contain illegal character such as ALT+ENTER whitespace.

Please help. Thanks.

What parser are you using? The sample you showed is definitely a valid XML. For example in .NET I successfully parsed this XML :

<?xml version="1.0" encoding="utf-8" ?>
<closedDeal>
  <customer><![CDATA[ABC ]]></customer>
</closedDeal>

using the following code:

using System;
using System.Xml.Linq;
using System.Xml.XPath;

public class Program
{
    static void Main(string[] args)
    {
        var doc = XElement.Load("test.xml");
        doc.XPathSelectElement("//customer");
        Console.WriteLine(doc.Value);
    }
}
