E.3 Notes on the XML Format

The following notes relate to the XML format of XML documents stored with Shunsaku:

• Preface sections (such as XML declarations and DTDs) cannot be searched or sorted.
• Namespace values, comments, and processing instructions cannot be searched or sorted.
• Text entered in CDATA sections can be searched and sorted. Tags entered in CDATA sections can also be searched and sorted, because they are handled as strings. Characters expressed in CDATA sections can also be sorted.
• Shunsaku does not check whether XML documents are valid when they are added or updated from an application or from the management console or a command.
• Use one of the following character codes for XML documents stored in Shunsaku:
  • The character identification code that was specified during standard installation
  • The character code specified in the CharacterCode parameter in the system environment file
• The default value of attribute specified by DTD declarations cannot be searched. The default value of attribute is also invalid for extracting and sorting. Refer to E.3.1 Setting Default Value of Attribute in DTD Declarations for more details.
• Evaluates to TRUE if duplicate attributes are specified in an element, and either attribute value contains the string characters or numeric values that match the condition. In addition, for the extracting and sorting process, the first attribute will be used.
• Do not use the '@' as the starting character for the element name when performing the search on the attribute value. The search may not be done correctly. Eliminate the '@' if using it as the starting character for the element name. Refer to E.3.2 Use @ as the Starting Character for the Element Name for more details.
• The normalization of the attribute value (replace the continuous spaces, returned character, linefeed character, or the horizontal tab with a space) will not be performed. The attribute value is the same status as entering in the XML document.
• If text node specified by text expression or the attribute node specified by the attribute expression in the direct access key definition file exists more than one in the same document, only the first text node value or the first attribute node value is used.
