Before I roll my own ARGV parse code I wanted to know if someone had
some sample code to get me started. I just want to be able to pass
simple switches that contain one parameter each to my perl app. I have
looked to the list first for I plan to accept the switches in any
order, but only allow each of them to be called once each. The only
important dependencies that I can think of right now is that switch -
cmd has to be passed if any other switch is used and all switches must
have a valid parameter. I'm not asking anyone to write me anything,
but any related sample code will help tremendously.
ex: perlscript -cmd show -type session -loc all
ex: perlscript -type process -cmd show
That did the trick. Thanks.

Hello,
I have included a section of code below
that is driving me nuts.
If I don't run the Substitution operations,
then I can successfully extract the URL
and the imbedded anchor text from
$parsed_html.
Once I include the Substitution operations,
then I cannot extract the same results.
Even though the output text looks theoretically
correct, I cannot see why any combination of the
Substitution operation breaks my code.
Can you offer any suggestions to me?

The above could cause problems later.
