searchPatterns

Type

Block tag.

Required

Yes.

Values

searchString, /regularExpression/, <empty>

• 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 <empty> 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:

<searchPattern>Field.Items</searchPattern>

<![CDATA[

/<%=\s*(\w+)\.Field\.Items\("(\w+)"\)/

]]>

</searchPattern>

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

/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:

<searchPattern>MY_OPTION_NAME</searchPattern>

</searchPattern>

</searchPatterns>

This example sets the optionLabel parameter to the entire innerHTML contents of an OPTION tag.

<searchPattern> attributes

The following items are valid attributes of the searchPattern tag.
