RE: Tivo OSD back

[Kevin Hawkins]

Hi Tony..

At the moment the xAP OSD feature only works for xPL multiline
osd.basic messages when the "Text" value is delimited with the \n
char. From
the below I now see that you can have identical repeating name value pairs
within one xPL message and there is an implicit sequential inference. I am
guessing this may be frequently used.

So.... if I wish to support this how do I use xpl.getparam within
xplHal to retrieve the repeated values - and how can I tell how many there
are ??

Is there anything easy like repeated calls to
xpl.getparam(xplMessage,"text",True) will return the next value
and null at
the end or do I use xpl.GetParamCount() and then test each one successively
for "text" and then read the values. Obviously I would like the
fastest
method possible.

Kevin
