358 Server Behaviors

Values

true, 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.

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.
