[Plugin: Google News Sitemap Generator] SPAN-Element in Title

I use a <span>-Element in my title,
and with this plugin the <span> is shown in Google News. Which is pretty ugly. ??

For example:
Before the new plugin it was shown like this in Google News:
The first part of my Headline: The second part!
Now it is shown like this:
<span>The first part of my Headline: </span>The second part!

Is there a way to make the plugin ignore the <span>-Tags?

Or the other solution: The plugin writes the TITLEs into the sitemap, instead of the URLs. How can I change the plugin code?

$xmlOutput.= "\t\t\t<n:title>";
$xmlOutput.= htmlspecialchars($row->post_title);
$xmlOutput.= "</n:title>\n";

into output URL?

Thanks.
