I found some old (dead?) Qt for Perl project(s) and was wondering if there
is such a thing as Perl Qt4 bindings?

9.11: How do I redirect to another page?

Specify the complete URL of the destination (even if it is on the same
server). This is one of the two different kinds of CGI "Location:"
responses which are defined in the CGI specification for a Parsed
Headers script. The other kind (an absolute URLpath) is resolved
internally to the server without any HTTP redirection. The CGI
specifications do not allow relative URLs in either case.

Use of CGI.pm is strongly recommended. This example shows redirection
with a complete URL. This redirection is handled by the web browser.

use CGI qw/:standard/;

my $url = 'http://www.cpan.org/';
print redirect($url);

I'm retrieving an XML result from a website and the the result changes
according to the number of Items returned.
if only one item returned the XML use a hash to hold the name and
value, however if more then one Item was returned it uses an Array to
hold all the results.
I'm trying to right a foreach statement to extract all the information
and when I get one Item I get an error that this is not an Aray
referance (which is obvius).
does anyone have a seggestion, how can I find if the results are in an
array or a hash?

Thanks

8.46: What's the difference between require and use?

Perl offers several different ways to include code from one file into
another. Here are the deltas between the various inclusion constructs:

1) do $file is like eval `cat $file`, except the former
1.1: searches @INC and updates %%INC.
1.2: bequeaths an *unrelated* lexical scope on the eval'ed code.

2) require $file is like do $file, except the former
2.1: checks for redundant loading, skipping already loaded files.
2.2: raises an exception on failure to find, compile, or execute $file.

3) require Module is like require "Module.pm", except the former
3.1: translates each "::" into your system's directory separator.
3.2: primes the parser to disambiguate class Module as an indirect object.

I have an XML hash that has $xmlResults->{Ack} = Failure
I use an if statement with $xmlResults->{Ack} == "Success" and getting
true instead of false.
I about to pull some hairs about and I don't have to many left, please
help me save the last ones I have.

thanks

dear group,

i have a little problem with the automatic conversion from unicode
entities in real characters by XML::DOM::Parser (or XML::Parser). for
example i have the string '&x#A0;' in a xml source file and i want it
after parsing with XML::DOM::Parser also in the target xml file.

begin source file:


Mathias Wuendisch

end source file:

begin perl script:
#!c:\perl\bin\perl.exe -w
use XML::DOM;
use strict;

9.4: How do I remove HTML from a string?

The most correct way (albeit not the fastest) is to use HTML::Parser
from CPAN. Another mostly correct way is to use HTML::FormatText which
not only removes HTML but also attempts to do a little simple formatting
of the resulting plain text.

Many folks attempt a simple-minded regular expression approach, like
"s/<.*?>//g", but that fails in many cases because the tags may continue
over line breaks, they may contain quoted angle-brackets, or HTML
comment may be present. Plus, folks forget to convert entities--like
"<" for example.

Here's one "simple-minded" approach, that works for most files:

#!/usr/bin/perl -p0777
s/<(?:[^>'"]*|(['"]).*?\1)*>//gs

We were just discussing this and weren't able to resolve:

Imagine I have a variable $var and I'd like to use the m modifier on a
regular expression to match a line ending with "word" and the next
beginning with "var":

if (/word$var/m) ...

how does perl treat this: as "word" anywhere on a line followed by
whatever is in $var or as I described above?
