The <log> element allows an application to generate a logging or debug message, which a developer can use to help in application development or post-execution analysis of application performance.
|label||A string used to give the log entry a label.|
|expr||An ECMAscript expression evaluating to a string.|
The contents of the log tag will be written straight into the standard logs as a “debugging” message. Verbose logging must be turned on in order to view these messages.
<?xml version="1.0"?> <vxml version="2.0"> <form> <field name="someinput" type="digits"> <prompt> Please say or enter some digits. </prompt> <filled> <log label="mylog">My log says <value expr="someinput"/></log> </filled> </field> </form> </vxml>
The output of the above script would be:
Computer: Please say or enter some digits.
Human: One two three four five six seven eight nine.
The following entry would then be added to the log:
Tue 19 Nov 2002 03:24:07 PM EST (000000;001;1037737318) [mylog] LOCAL: My log says 123456789
