无法解析带有嵌套CDATA部分的XML

Question

I am having a problem while parsing XML with nested CDATA section. The CDATA section is as below:

<![CDATA[*** some text

[ !  <![CDATA[some text]]>  ! ]

<![CDATA[some text]]>

]]>

When this type of data is appearing in an XML tag, it is giving an error while parsing the XML as there are two closing tags ]]>. Can anyone please suggest me what to do or what character should I escape to make this work? I am using Java1.8.

Answer 1

The reason you are having trouble parsing this input is that it isn't XML. You need to find out what program is generating this non-XML and fix it.

If you are generating XML, then whenever you create a text node that might contain the sequence ]]> (whether or not this represents the end of a nested CDATA section) you need to escape it somehow. Many people take the path of least resistance and simply escape > as > wherever it occurs, but technically this is needed only if the > is preceded by ]] .
