This is one of those common misconceptions. First of all, if you want to include ]]> in a single CDATA section, you simply cannot. In order to accomplish this, you need to break the text up into two text nodes, where the first text node contains at least ] and at most ]], and the second contains ]> or >. The reason that you need to escape the > in ]]> is for compatibility with SGML parsers, which recognize this as a special sequence [a marked section end] in text and cause parsing errors. Some parsers and DOM implementations will quietly merge adjacent text nodes on input. The DOMM also contains a method to normalize adjacent text nodes into a single node, so having to use two text nodes for the data is usually not a problem. Text inside <![CDATA[ ]]> does not undergo replacement. In SGML terms, it is character data, which, unlike replacable character data, is not subject to any substitutions whatsoever.

Subject: Discussion about XML Specification(SE) Hi,all: The following is an actual text in XML Specification(SE). <originText> The right angle bracket (>) may be represented using the string ">", and must, for compatibility, be escaped using ">" or a character reference when it appears in the string "]]>" in content, when that string is not marking the end of a CDATA section. </originText> According to the above description, we are supposed to escape '>' using '>'. But the problem is that is there another way for us, in the content of CDATA section, to write the '>' in ']]>' without using a '>'? I find out there isn't such a method. So actuall we MUST do that, instead of FOR COMPATIBILITY, which is descripted in the XML specification(SE). Collin
