Adrien,

That's what I thought. But now I found my problem.

The special characters are in the attributes of the element, not in the text content.  Here's an example:

(racenode is an XMLElement)

? racenode.Tostring(true)
<Race RaceNo="8" RaceTime="2014-06-25T15:55:00" RaceName="C,G&E 0 - 68 HANDICAP" Distance="1211" WeatherChanged="N" WeatherCond="3" WeatherDesc="Showery" TrackChanged="N" TrackCond="5" TrackDesc="Heavy">
( inner content excised )
</Race>

I'm looking at a bit of code that is:
    $title = raceNode.Attributes["RaceName"]
which ends up with the raw value, viz
    C,G&E 0 - 68 HANDICAP

Is there a way to get an attribute value "de-specialed"?
