Participant EDML files 355

■ 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".

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.

paramNames

Description

This attribute is a comma-separated list of parameter names whose values are being extracted.

These parameters are assigned in the order of the subexpression. You can assign single

parameters or use a comma-separated list to assign multiple parameters. If other parenthetical

expressions are used but do not indicate parameters, extra commas can be used as placeholders

in the Parameter Name list.

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/.
