[mythtv-users] Problem with mythfilldatabase and home-brew grabber

[Ian Macdonald]

Hello,

I'm in Amsterdam, The Netherlands, where the standard XMLTV grabber,
tv_grab_nl, grabs programme data from tvgids.nl.

Unfortunately, tvgids.nl does not have programme information for many
channels available in the local cable network's digital package.

For that reason, I'm writing a new grabber to pull data from a second
source.

Well, I basically have the grabber written, pulling data and outputting
a valid XMLTV file, but when the program is run via mythfilldatabase,
the latter complains about an unexpected end-of-file:

Note that the above sample run has only channel data, but no programme
data. In reality, there's much more output, but the error message is the
same.

I can't understand why it's complaining. I've compared the output of my
grabber with various others and it's identical in structure. In fact, if
I cut and paste some output from those others into a shell script called
tv_grab_nl, which cats that output to stdout via a mythfilldatabase run,
I get the same error.

So I think it has less to do with my XML and more to do with how the
script is actually called or where the output goes (although it just
goes to stdout, like all of the grabbers).

This has got to be something really obvious that I'm just not thinking
of.

Does anyone have any ideas?

And what does the '1:1' mean in the error message? Line 1, character 1?
That makes me think that mythfilldatabase doesn't even see the output,
even though it's right there on stdout and printed in the log.

I'd be grateful for any help received.

Cheers,

Ian
