xml data

[oberwetter]

Below is a tiny program that gets an xml file using the <data> tag and calls a script passing it the tag name and the data value is supposed to be returned.
This runs as written correctly on Voxeo and Bevocal. The text "This is the text from the xml file." is spoken.
But on Plum I get the error "A serious error of type error.semantic has occurred. Exiting." Why is that?
The first two log entries show the value xxxxxx vvvvvvv. The second two log entries show the value { } { }

I am trying to migrate my code to plum to use it for hosting and this is a show stopper.

Thanks,

Robert

Hello,

When accessing data from an XML DOM structure it is necessary for you to convert the data to a String before handing it off to our TTS engine:

Code: Select all

<script>
<![CDATA[
// retrieve the value contained in the node t from the DOM exposed by d
function GetData(d, t, nodata) {
	try {
		return d.getElementsByTagName(t).item(0).firstChild.data.toString();
	} catch(e) {
		// the value could not be retrieved, so return this instead
		return nodata;
	}
}
]]>
</script>

This tells the IVR system to convert the data at that node to a string. The IVR issue was also covered recently on this forum: http://support.plumvoice.com/viewtopic.php?t=414. Hope this helps.

Plum Support

It worked. The solution was so simple after being so difficult to isolate.

Thanks.
