B-14 Videojet DataFlex 6530 Service Manual - Rev AA

Alternately, if the character is not one of the above and still does not work correctly (e.g any

character with an ASCII code >= 128), you may use a CDATA section. This is done by simply

enclosing the required text with <![CDATA[ ]]>. Reserved xml characters should not be escaped

in the CDATA section.

So to print the text “Español & Français” in a field called “Languages” the XML should contain:

3. White space characters are not printed correctly. White space characters are usually

truncated into a single space, because XML is a free format structure. To overcome this use a

CDATA section as described in 2.

4. The field names are not correct. Ensure that the field names are matched exactly. This

includes the case of each character, and the white space.

5. The ReferenceCiff attribute is present and does not match the name of the CIFF file that is

being used. Ensure that the name in the SEL message matches the ReferenceCiff name.

6. The data is being truncated or characters are missing. Data entered into a user entered field

uses exactly the same validation as is used for user entry. This means that if the field is setup

for “Numeric Only”, then only numbers are allowed in the field, and any other characters are

discarded. The data is also truncated to the maximum length specified within the CIFF file.

Advanced Features

This section covers items such as double byte (Unicode) strings; preserving white space padding

and multiple data object fields and counters.

Unicode CIFF Data Files

In certain applications, it is necessary to enter characters that are not part of the Western

European character set. In order to achieve this, the XML file needs to be encoded in the Unicode

character set. Unicode is a 16-bit character set capable of encoding almost all known characters

and is used as a worldwide character-encoding standard.

To identify the CIFF data file as a Unicode XML file, a processing instruction needs to be added

to the start of the file that reads "<?xml version=”1.0” encoding=”UTF-16” ?>”. So to update a

field with Arabic text:

<?xml version=”1.0” encoding=”UTF-16” ?>

</ImageData>

The simplest way of creating a Unicode XML file is to create it in Notepad on a Windows

NT/2000/XP system and then in the save dialog, select the encoding as Unicode.

White Space Characters

XML has a free format structure which can lead to problems when the field data has to contain

multiple white space characters (space, tab and return characters). Where there is a run of

consecutive white space characters, an XML parser usually truncates this to a single space. In

order to avoid this, wrap the text in a CDATA section.

The following examples show what would be printed with and without a CDATA section.

1. <Field Name=”SomeText”>A 0001</Field> would print “A 0001”.

2. <Field Name=”SomeText”> <![CDATA[A 0001]]></Field> would print “A 0001”.
