![]() Nesting is not allowed in CDATA section.CDATA cannot contain the string "]]>" anywhere in the XML document.The given rules are required to be followed for XML CDATA − In the above syntax, everything between and is treated as character data and not as markup. Here, each character written inside the CDATA section is ignored by the parser. The XML dissector is not an XML validator It uses the DTDs just to be able to extract information for the filtering engine. and it has the ability to load XML DTDs and use them to choose the filter fields to be used when parsing XML. ![]() The following markup code shows an example of CDATA. Wireshark The XML dissector is fully functional. This section may contain markup characters (, and &), but they are ignored by the XML processor. 1 import 2 3 def unescape(s): 4 wantunicode False 5 if isinstance(s, unicode): 6 s s.encode('utf-8') 7 wantunicode True 8 9 the rest of this assumes that s is UTF-8 10 list 11 12 create and initialize a parser object 13 p ('utf-8') 14 p.buffertext True 15 p.returnsunicode. The above syntax is composed of three sections −ĬDATA Start section − CDATA begins with the nine-character delimiter delimiter.ĬData section − Characters between these two enclosures are interpreted as characters, and not as markup. The key differences between CDATA and comments are: As Richard points out, CDATA is still part of the document, while a comment is not. Syntaxįollowing is the syntax for CDATA section − CDATA stands for Character Data and it means that the data in between these strings includes data that could be interpreted as XML markup, but should not be. By using CDATA section, you are commanding the parser that the particular section of the document contains no markup and should be treated as regular text. Syntax Following is the syntax for CDATA section < CDATA characters with markup > The above syntax is composed of three sections CDATA Start section CDATA begins with the nine-character delimiter < CDATA CDATA End section CDATA section ends with > delimiter.In such cases, CDATA section can be used. ![]() ![]() CDATA is defined as blocks of text that are not parsed by the parser, but are otherwise recognized as markup. In this chapter, we will discuss XML CDATA section. ![]()
