searchPatterns
Type
Block tag.
Required
Yes.
Values
searchString, /regularExpression/,
• The searchString value is a simple search string that is case-sensitive. It cannot be used to extract parameters.
• The /regularExpression/ value is a regular expression search pattern.
• The value is used if no pattern is given. It is always considered a match, and the entire value is assigned to
the first parameter.
In the following example, to identify the participant text <%= RS1.Field.Items("author_id") %> , you can define
a simple pattern, followed by a precise pattern that also extracts the two parameter values:
Field.Items
This example matches the pattern precisely and assigns the value of the first subexpression ( \w+ ) to parameter rs and
the second subexpression ( \w+ ) to parameter col .
Note: It is important that regular expressions start and end with a slash (/). Otherwise, the expression is used as a literal
string search. Regular expressions can be followed by the regular-expression modifier
i to indicate case-insensitivity (as
in /pattern/i ). For example, VBScript is not case-sensitive, so it should use /pattern/i . JavaScript is case-sensitive
and should use /pattern/ .
Sometimes you might want to assign the entire contents of the limited search location to a parameter. In that case,
provide no pattern, as shown in the following example:
MY_OPTION_NAME
This example sets the optionLabel parameter to the entire innerHTML contents of an OPTION tag.
attributes
The following items are valid attributes of the searchPattern tag.
