CDATA in XML

Introduction

In the world of XML, CDATA (character data) plays a crucial role in ensuring the integrity and validity of XML documents. CDATA allows authors to embed unparsed text within an XML document without triggering the parser's interpretation of tags or entities.

How does CDATA work?

CDATA is enclosed within the following syntax:

``` ```

Within the CDATA section, the parser treats all characters as plain text, regardless of whether they resemble markup tags or entities. This prevents the parser from interpreting and altering the raw data, preserving its original form.

Applications of CDATA

CDATA finds numerous applications in XML development, including:

• Embedding JavaScript or other programming code without triggering the parser's interpretation of special characters.
• Including external content, such as snippets of HTML or CSS, without modifying the original formatting.
• Storing sensitive or confidential information that should not be parsed or processed by the document.
