I often find this strange CDATA tag in XML files: <![CDATA[some stuff]]> I have observed that this CDATA tag always comes at the beginning, and then followed by some stuff.. But sometimes it is used, sometimes it is not. I assume it is to mark that some stuff is the "data" that will be inserted after that. But what kind of data is some stuff?Isn't anything I write in XML tags s...


XML 1.0 (Fifth Edition) and XML 1.1 support the direct use of almost any Unicode character in element names, attributes, comments, character data, and processing instructions (other than the ones that have special symbolic meaning in XML itself, such as the less-than sign, "<").


XML data is known as self-describing or self-defining, meaning that the structure of the data is embedded with the data, thus when the data arrives there is no need to pre-build the structure to store the data; it is dynamically understood within the XML.


In Chapter 1, Introduction to XML, we learned a few things about how XML is structured and what you can do with it.My goal for that chapter was to show you how flexible XML really is. In this ...


In short, parsing XML means that a program generates an internal representation of the serialized XML. As an example, let's use HTML. HTML parsing is essentially the same as XML parsing (except the syntax is slightly different, but that doesn't matter right now).

An XML document is a great way to represent information. But some characters, such as the ampersand, can be problematic because they have special meaning. Here is how to avoid the pitfalls ...


Although the design of XML focuses on documents, it is widely used for the representation of arbitrary data structures, for example in web services. Many application programming interfaces have been developed to aid software developers with processing XML data, and several schema systems exist to aid in the definition of XML-based languages.


The XML prolog is optional. If it exists, it must come first in the document. XML documents can contain international characters, like Norwegian øæå or French êèé. To avoid errors, you should specify the encoding used, or save your XML files as UTF-8. UTF-8 is the default character encoding for XML documents.


CDATA sections are used when larger amounts of verbatim text need to appear within XML documents and processed verbatim. Smaller quantities of such text can be properly encoded to escape the XML characters, but for larger text, it helps to preserve the meaning of the text without having to do so.
