The XML parsers normally parse the complete text in an XML document i.e., when an XML element is parsed, the text data between the XML tags is also parsed. Consider the following example:,
<message>This text will also be parsed</message>
In this example, the message between the <message> and </message> text will normally be parsed by the XML parser. Consider another example:
<name><first>Hello</first><last>User!</last></name>
...
A CDATA section starts with "<![CDATA[" and ends with "]]>". CDATA sections are useful for writing XML code as text data within an XML document.
A CDATA section cannot contain the string "]]>" and therefore it is not possible for a CDATA section to contain nested CDATA sections.
You can use multiple CDATA sections by splitting each occurrence of the "]]>"just before the ">".
Steps to add a CData section
- Ensure that the source and target schemas destination layouts are loaded and all their elements are listed under their respective nodes.
Click Actions menu and select the option CData Section Elements (see Figure 559).
Figure 557: CData Section Elements
- The CData Section Elements dialog is displayed (see Figure 558).
...
Select the element of the destination layout, click more icon and then select Add to CDATA Section Elements option.
- It displays the CDATA in element.
