testing Non_SOAP webservices
Hi gurus, I need to test non-SOAP webservices.Can anybody tell how could i do that in perl. basically i need to send the following xml file as pay load to the url. - ?xml version='1.0' encoding='UTF-8'? ns1:getHelloResp xmlns:ns1=http://sample2/xsd; ns1:req ns1:type=samples.HelloReq ns1:nameNag/ns1:name ns1:count3/ns1:count /ns1:req /ns1:getHelloResp --- and get the response can anybody in the group help me in doing this using perl. thanks, Siva --

OO question
Hi All,
I am trying to work with the CGI::FormBuilder module in a Catalyst
environment. My question is more about OO programming than either of those 2
modules though.
I am trying to create a method/sub that will create a form to either edit or
add an entry. I am creating the initial object and depending on whether or
not the entry already exists, I want to set-up some aspects of my object
(making sense??). So I want to create the object, assign it to a variable
and make changes to it (or not) later depending on some condition. Here's an
abridged version of what I have done so far:
use strict;
use warnings;
...snip
sub edit : Local Form {
my ($self, $c, $id) = @_;
# Here comes my form
my $fb = $self-formbuilder-field(
name = 'Users',
type = 'select',
options =
[ map { [ $_ - id, $_-code ] }
$c-model('Files::users')-all ],
required = 1,
#value = undef
);
...
if ($id) {
$fb-{value} = $some_default_val;
}
}
So I guess the question is what sort of structure have I created initially
with $fb and $self and does $fb-{value} make sense. Can I add an attribute
to an object after I've created it in this way.
I hope that makes sense. I am almost confusing myself here :-)
Thanx.

Are comments allowed before package declarations in modules?
I seem to have a vague memory about Perl not allowing comments before program statements, but I'm not sure. I really want to add a lot of comments at the top of a rather large module, but I'm unsure if thats safe. thanks

Go back to basics. An object is just a hash[1], a reference to which
happens to be blessed into a specific class. But it's still just a
hash. Anything you can do to a normal hash, you can do to an object.
That includes adding new key/value pairs to it.
So yes, it's perfectly allowed. No reason you can't.
Paul Lalli
[1] in this case, of course. You're equally able to make an object
out of a reference to a scalar, an array, a filehandle, or pretty much
anything else...

In addition to the answers already received, you could take advantage
of the List::MoreUtils module from CPAN:
#!/usr/bin/perl
use strict;
use warnings;
use List::MoreUtils qw/zip natatime/;
my @foo = (1, 2, 3);
my @bar = qw/a b c/;
my $it = natatime 2, zip(@foo, @bar);
while (my ($f, $b) = $it-()) {
print $f - $b;
}

skip 8 characters and match '150'
skip 19 more characters and match '24' and '510'
skip 21 more characters and capture the next 6 in $tract
capture the next character in $bg
and print them.
The first two matches work, but nothing is captured. Any ideas what I'm
doing wrong?

On what do you base your assumption that the first two matches
work? Nothing in your code or output indicates that, as you are
never checking the return value of the pattern match.
FWIW, your code did work for me when I copy and pasted your sample
text, and joined the lines as they should have been. Therefore, I
think it's pretty likely that your datafile does not contain what you
think it does. I think it's more likely that the one line you think
you have that starts with uSF is actually broken up into a few lines.
Try some debugging prints of $_ to see what you actually have, like:
print Line $.: $_;
Try checking the return value of your regexp:
/^.{8}150.{18}24510.{21}(.{6})(.)/ and print Tract $1 BLKGRP $2\n;
Try enabling warnings to see of your two variables are undefined
(which they would be if the pattern didn't match) or just empty
strings (which they would be if the pattern matched but nothing was
captured - this, of course, isn't possible, since a six-character
match can't possibly be the empty string).

RE: Why doesn't this work: matching capturing
Paul, thank you very much for your helpful reply. To answer your question, I am
certain that the first two matches worked because I produced the output I
showed with:

A person responded to me privately and suggested this modification, which seems
to work fine:
[EMAIL PROTECTED] UScensus]$ perl -ne 'print Tract $1 BLKGRP $2\n if
/^.{8}150.{18}24510.{21}(.{6})(.)/;' mdgeo.uf1 |head -3

I've been bitten by this bug before and can never remember the solution to when
variables are assigned values. I thought assigning them in a previous command
would have worked, but I must have overlooked something.

Check if a given function returns something
Hi All,
I want to check if a sub routine that I am calling returns a value
or not.
This is how my code is
$str = function(parameter)
sub function
{
..
}
the sub routine function in turn uses many other function. Some of these
functions have a return statement and some do not.
So, when i invoke the sub routine function and i pass the returned value into
$str, I need to check if $str has any value assigned or not.
Can you tell me how I could accomplish this?
Thanks,
Vijay
