Participant EDML files 277
Type
Attribute.
Required
No.
Values

, false
• The value is true if the searchPattern is not necessary to identify the participant.
• The value is false (default) if the searchPattern tag is required.
For example, consider the following simple recordset string:
<%
var Recordset1 = Server.CreateObject("ADODB.Recordset");
Recordset1.ActiveConnection = "dsn=andescoffee;";
Recordset1.Source = "SELECT * FROM PressReleases";
Recordset1.CursorType = 3;
Recordset1.Open();
%>
The search patterns must identify the participant and extract several parameters. However,
if a parameter such as
cursorType is not found, you should still recognize this pattern as a
recordset. The
cursor parameter is optional. In the EDML, the search patterns might look like
the following example:
<searchPattern paramNames="rs">/var (\w+) = Server.CreateObject/
</searchPattern>
<searchPattern paramNames="src">/ActiveConnection = "([^\r\n]*)"/¬
</searchPattern>
<searchPattern paramNames="conn">/Source = "([^\r\n]*)"/¬
</searchPattern>
<searchPattern paramNames="cursor" isOptional="true">¬
/CursorType = (\d+)/
</searchPattern>
The first three patterns are required to identify the recordset. If the last parameter is not found,
the recordset is still identified.
<updatePatterns>
Description
This optional advanced feature lets you update the participant precisely. Without this tag, the
participant is updated automatically by replacing the entire participant text each time. If you
specify an
<updatePatterns> tag, it must contain specific patterns to find and replace each
parameter within the participant.
This tag is beneficial if the user edits the participant text. It performs precise updates only to the
parts of the text that need changing.
