<assign name="audium_vxmlLog" expr="audium_vxmlLog+'|||audio_group$$$xyz^^^' + 
application.getElapsedTime(audium_element_start_time_millisecs)"/> 

Note that the 

expr

 attribute of 

<assign>

 is used because the value is actually an expression that 

concatenates various strings together.  First, the 

audium_vxmlLog

 variable must be listed because 

we are appending new data to it. We append the string listing the audio group action and the 
name of the audio group, all contained within single quotes because this is a string literal. The 
final part is the Javascript, which cannot be within single quotes. 

To do this within a voice element, one would have to use the 

VAction

 object (since it handles the 

<assign>

 tag) like this: 

VAction log = VAction.getNew(pref, VAction.ASSIGN,  
  

VXML_LOG_VARIABLE_NAME, 

 

VXML_LOG_VARIABLE_NAME + "+'|||audio_group" + 

 

"$$$xyz^^^' + application.getElapsedTime(" + 

            

ELEMENT_START_TIME_MILLISECS + ")",  

 VAction.WITHOUT_QUOTES); 

Note that the 

audium_vxmlLog

 and 

audium_element_start_time_millisecs

 variables are not 

mentioned by name, the 

VXML_LOG_VARIABLE_NAME

 and 

ELEMENT_START_TIME_MILLISECS

 Java 

constants are used instead. Where Java constants are used, they must appear outside the double 
quotes defining the string. Also note that 

pref

 is expected to be a valid 

VPreference

 object. 

In a more complex example, the utterance of a field named xyz is to be appended to the log. The 
utterance is determined by a VoiceXML shadow variable. The VoiceXML would look like: 

 

<assign name="audium_vxmlLog" expr="audium_vxmlLog + '|||utterance$$$' + 

xyz.$utterance + '^^^' + application.getElapsedTime( 
audium_element_start_time_millisecs)"/> 

and the 

VAction

 object would be configured like: 

VAction log = VAction.getNew(pref, VAction.ASSIGN,  
  

VXML_LOG_VARIABLE_NAME, 

 

VXML_LOG_VARIABLE_NAME + "+'|||utterance" + 

 

"$$$' + xyz.$utterance + '^^^' + " + 

 "application.getElapsedTime(" 

+ 

 

ELEMENT_START_TIME_MILLISECS + ")",  

 VAction.WITHOUT_QUOTES); 

See Chapter 5 in the User Guide for more detail about the different logs CVP VoiceXML Server 
records and the data that can appear in the logs.
