   RE: [xml-dev] Discussion about XML Specification(SE)

[ Lists Home | Date Index | Thread Index ]

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

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: [xml-dev] Discussion about XML Specification(SE)

    The following is an actual text in XML Specification(SE).
        The right angle bracket (>) may be represented using the string
"&gt;", and         must, for compatibility, be escaped using "&gt;" or a
character reference             when it appears in the string "]]>" in
content, when that string is not             marking the end of a CDATA
    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 '&gt;'?
    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
