| No validation
|
This option is set by default. Zone values are not validated. Note: The resulting RRT will contain an empty
string, if the zone contains unrecognizable characters; if the zone does not contain anything, then there will be no value
passed to the resulting RRT.
|
| Contains something
|
This option says that the zone must contain some valid value depending on zone type. If no valid value is found in the
zone, it is identified as empty. Note: If the zone does not contain anything or its content is unrecognizable, then
there will be no value passed to the resulting RRT.
|
| Matches wildcard
|
This option allows using wild cards to validate those zone values which satisfy the defined pattern:
| Wildcard |
Description |
| * |
any value of any length |
| ? |
any single character |
| [A] |
any single alphabetic character |
| [#] |
any single numeric character |
| [A#], [#A] |
any letter or a number |
Note: If you want symbols such as *?[]\ to be interpreted as characters (not as wild cards), use the slash as the
escape character: \*, \?, \[, \], \\. For example, to interpret the symbols in the string [a*b]*c as literal characters,
use the following expression: \[a\*b\]\*c.
|
| Matches regular expression
|
This option says that the zone value must match a regular expression. All standard operations are allowed: ., *, +, |, [],
^, $ ? and grouping with ().
| Regular expression |
Description |
| a |
a where a is any symbol excluding symbols (|)[].*+^$\?
For example: f is character "f”; 5 is character "5”.
|
| \a
|
a where a is any symbol including (|)[].*+^$\?
To represent any symbol "as is”, precede it with a the backslash character. You can use the backslash and
an escape character to interpret special characters literally, including characters inside of
CharSet. To include the backslash character ( \ ) as a literal character, prefix it
with the backslash ( \\ ).
For example: \* means character "*” and \a means character
"a”.
|
| . |
Any single symbol.
For example: expression 11.5 corresponds to such combinations of characters as
"1135”, "11f5”, "11_5”.
|
| RegExp |
Any regular expression RegExp.
For instance, 112 represents sequence "112”, which can be found inside a string
(not the whole string only!).
|
| RegExp1|RegExp2 |
Any one of expressions RegExp1 or RegExp2
For example, expression 1|3 validates any of symbols "1” or "3”.
Note: The concatenation has priority in comparison with alternation construct. This means that
combination 12.5|78 corresponds not to "12(any number)(then 5 or 7)8", but it
corresponds to "(12(any number)5) or (78)". So, the representations of this example can be: "1235",
"12f5", "78".
|
| RegExp+ |
Regular expression RegExp repeated one or more times.
Use this expression to find sequences of desired characters
For example, (1|3)+ will find expressions (1|3), (1|3)(1|3).
|
| RegExp* |
Regular expression RegExp repeated zero or more times. |
| RegExp? |
Regular expression RegExp repeated zero or one time. |
| RegExp1RegExp2 |
Sequence of two expressions: RegExp1 then RegExp2.
For example, (1|3)(11.5) corresponds to such combinations as "11175”, "311t5”.
|
| ^ |
Beginning of string.
Use this symbol to find strings which begin with predefined regular expression. The desired expression
must follow ^ sign.
For example:
|
| $ |
End of string.
Use this symbol to find strings which end with predefined regular expression. The desired expression must
precede $ sign. Expression ^RegExp$ corresponds to the whole string only.
For example:
-
Expression 5$ corresponds to all strings which end with "5”;
-
(1|3)$ — All strings which end with "1” or "3”;
-
^(a|c)..123.$ represents whole strings which begin with "a” or "c” then have
any two characters, then sequence "123” and end with any character: "age123y”, "cat1234”.
|
| [CharSet] |
Any single symbol belonging to a character set CharSet.
The CharSet is specified as a character string and includes all symbols of the string.
The order of characters doesn't matter. A "-” sign inside of the CharSet has a special
meaning and is used to represent a characters interval.
For example, expression [12a-e34] means the same as [12abcde34], it stands for any
character "1”, "2”, "3”, "4”, "a”, "b”, "c”, "d” or "e”.
|
| [^CharSet] |
Any symbol not belonging to manifold CharSet.
For example, [^12a-e34] means any character excluding "1”, "2”, "3”, "4”, "a”,
"b”, "c”, "d” and "e”.
Note: Other symbols inside brackets are considered as characters but not special symbols. For
instance, [$] is not a symbol of end of string but it is a character "$”. Symbol ^ must stand right after
"[", otherwise it means just a character "^”.

|
| Validated by external script
|
Zones will be verified by the use of the defined VB script. Input the path to the script in the Script file
name field or browse the script. The script receives the following data at input:
- sValue — The zone value with line feed
- sTrimmedValue — The zone value without line feed
- sFileName — Input file name
- nPageNumber — Page number
If the zone is validated, it returns value "TRUE" or "YES" for string variable RRV. If validation fails, the script
returns "FALSE" for RRV. Example of the validation script:
val = sValue
fn = sFileName
num = nPageNum
if sTrimmed
Value = "Vinci" then
RRV = "TRUE"
else
RRV = "FALSE"
end if
|
| Contains substring
|
This option says that the zone value must contain the specified text. If the text is not found in the zone, it is
identified as empty. |
