switch to the object syntax,
$req-meta(...)

Note you probably need $req-referer in the above line...
Yes, this was it. I am using object syntax, so $req-meta() worked.
Yes, the above $req-refere was a type, I am using $req-referer()
HTH,

This seems to be what is documented on cpan. I must be missing something
simple. Any ideas?

Re: Complex regex help
Omega -1911 am Freitag, 1. Dezember 2006 06:05:
Hello all,
I am trying to parse calendar events for a rss feed into variables. Can
someone help with building the following regex or point me in the direction
of some good examples? Thanks in advance.
Here is what I have tried: (I don't know much about complex regex's as you
see)
$mystring =~ /.+(plib)(\w+) (FONT COLOR=\\#99\)(\w+)(\[Ref
\#(\d+\])(.+)$/);
Here is a sample string:
plib DATE FONT COLOR=#99TITLE/FONT/b EVENT a href=
http://www.mysite.comtarget=_new;www.mysite.com/a [Ref #67579]/li
What I would like to pull out is the TITLE EVENT information. The sample
string is the format for each event. Any takers on this? Again, thanks for
any help.
If you *really* want do it with a regex, and not a parser (XML::LibXML,
XML::Simple, etc.), here is one possibility.
However, note that a regex is very fragile if it comes to format changes, or
the input has unexpected chars in it. In the regex below, I try to be
flexible concerning white space in the input; one could also be more specific
in the part following the info to extract.
There are generally two somehow contradicting aims:
- be most specific to not match unwanted content
- be liberal to handle format changes
How did you develop the regex? It seems not to match as you liked. One way is
to build it step by step; starting with matching strings between p/p,
ckecking, be more specific, checking etc.
Note that I escape the '#' in the regex because of the /x modifier that allows
comments.
BEWARE: Id did not spend hours. It just extracts what you want from the $input
present.
#!/usr/bin/perl
use strict; use warnings;
my $input='
plib DATE FONT COLOR=#99TITLE1/FONT/b EVENT1
a href=http://www.mysite.comtarget=_new;www.mysite.com/a
[Ref #67579]/li/p
plib DATE FONT COLOR=#99TITLE2/FONT/b EVENT2
a href=http://www.mysite.comtarget=_new;www.mysite.com/a
[Ref #67579]/li/p
';
my %info = $input =~ m;
p\s*
li\s*
b.*?
font\s*color\s*=\s*\#99[^]*?\s*(.*?)\s*/font\s*
/b\s*(.*?)\s*a.*?/a\s*\[ref[^\]]+?\]\s*
/li\s*
/p
;mgxsi;
print map { $_ = $info{$_}\n } sort keys %info;

Hi Dave Better than using regexes to extract the information, which are notoriously poor at processing HTML, would be to use one of the the bespoke HTML parsing modules. My preference is HTML::TreeBuilder, which builds a structure of HTML::Element objects to represent the original document. From that it is easy to extract the parts you need according to their context. Can you let us have a URL for the information so that we can help you a little better? Or at least an example with several records that you need to process.

On 12/1/06, Brent Clark [EMAIL PROTECTED] wrote: I keep getting this Running make test Can't test without successful make That means that the make stage - which builds your new module - didn't succeed, for some reason. Maybe your system is missing some key component, say. Since the module didn't get built, you're stuck. If the CPAN module isn't giving you a diagnostic message with more information about the reason for the failure, you should try installing the module directly, i.e. without the CPAN module. See the new module's README, or use the instructions in the perlmodinstall manpage, at least until you get to a useful diagnostic message.

that single command does most of what i need, I can just pipe the output
to pfctl to add it to the firewall block list. however i still have the
problem of it checking the entire file instead of the first line. In
addition im seeing a version number in the headers like V6.2000.20.5

can list all the files in the directory eaisy enough,.. i was going to
have that script supply the filename and fire off another script which
searched for the IP in individual files,.. I think its a waste of
processing power to scan the entire file when i just need the first
line. Is there an eaisy way to limit the search to the first line?
some code
the first one returns each filename in the directory.
#!/usr/bin/perl -w
use strict;
my $file;
my $dir = mail/;
opendir(BIN, $dir) or die Can't open $dir: $!;
while( defined ($file = readdir BIN) ) {
next if $file =~ /^\.\.?$/; # skip . and ..
print $file\n if -T $dir/$file;
}
closedir(BIN);

the second one searches a single file for IP addresses. (I left in my
failed attempts to get the regex correct,.. figured it might make
someone happy to know that there are worse coders out there than
themselves)

I finally made it to page 132 in Learning Perl and discovered the
command line syntax.
perl -n -w -e 'if (/\d+\.\d+\.\d+\.\d+/){ print $\n;}' mail/mail*
that single command does most of what i need, I can just pipe the output
to pfctl to add it to the firewall block list. however i still have the
problem of it checking the entire file instead of the first line. In
addition im seeing a version number in the headers like V6.2000.20.5
which matches my regular expresion. If i can narrow it down to the first
line of the file this wont be a problem.
Use the Regexp::Common::net module for this.

Re: Complex regex help
Omega -1911 am Freitag, 1. Dezember 2006 19:01: Hi Rob Dani, Hello Omega Thanks for your help!!! I will try the suggestion you made Rob and as soon as I finish typing this, I'll try Dani's code. I had someone contact me off-list and provided me with the following regex that appeared to work. Please let me know what you think: my( $title, $event) = $data_string =~ m|([^]*)(?:/FONT/b)([^\]]*)([^]*)|; First I'd like to emphasize that Rob's suggestion (use a parser module, not a regex) is really the preferred way. Consequently, I should not have mentioned a regex... I see at least the following problems with the above regex (there are others, as well as in mine): - It captures three peaces of the input, while on the left side are only two variables to put the peaces in. - When I run it, it matches too much into $event (event up to the Ref # without the trailing ']' - the latter is put in $3). - ... In short: A parser module will avoid a lot of trickiness, pitfalls, error proneness, problems [pick the right english term(s) if present] :-) Just forget the regex path.

Please let me know what you think: my( $title, $event) = $data_string =~ m|([^]*)(?:/FONT/b)([^\]]*)([^]*)|; Hello Dave You will need help to use HTML::TreeBuilder as it's fairly complex, and to help you we need fuller information on the HTML you're processing. Can you publish a bigger chunk? Or, better still, the URL where it is coming from? The regex doesn't look right at all, the (?: .. ) around the closing font and bold tags has no effect, and the ] in the character class needn't be escaped. Apart from that it will grab everything from EVENT up to the end of the Ref # value into $event and the closing ] into $3 which is then discarded. Not good at all. Against my better judgement I could offer my @stuff = $data =~ /\s*([^]+)\s*/g; which will return all the text between the HTML tags, but this will fall down if you have something like i.../i in the middle of one of the fields, which will result in the text being broken into multiple segments. Better all round to use a proper parser.

Limit of number of files that can be opened in perl
Hi: is there a limit on number of files that can be open within perl. I am opening about 194 files and am seeing some weird behaviour. When i write to the filehandles, I see it writes ok to some files and not to the others. But I donot see any errors either. Just that somefiles donot have what I am expecting. If there is a limit, how do I work around it? Thanks Ravi Do you Yahoo!? Everyone is raving about the all-new Yahoo!

What debugging do you have in place, error messages etc? If some files aren't being written to, where are they being written (Hint: have you checked the return value of your write statement?)
