No one replays my question by now. I just send again to bring up your
attention. Thanks ahead.

Subject: [xsl] failed to find the right child node

I am trying to find out whether all channel objects are in the same
networks. Each legacy_stream has a different network_id which indicates
different 
Networks. I plan to recursively check all fast_load stream, if it
contains channel object, I will increase sum of networks by 1. At the
end, I will check the sum of network, if it is larger than one, I will
assign a Boolean false value to indicate that all channels are in the
different network. Otherwise, I will assign a Boolean true value.
But, when I try to check each fast_load_stream by using  select
="//fast_load_stream[position()=$index]", it does not work. Could you
please help me to find out what's wrong in my code?

Here is my xslt file. I use some xsl:value-of to print out some outputs
for debug purpose.
