Re: XML processing

Seconding borisz's advice, here's some (untested) XML::Twig code to do this, in case you want to continue doing stuff with the results in perl:

use XML::Twig;

# ...

my $twig = XML::Twig->new();
$twig->parsefile($XmlFile);

my @a_elements = $twig->get_xpath("//a");

foreach my $el (@a_elements)
{
  my $text = $el->text();
  # do stuff with $text.
}
[download]

It's actually pretty easy, once you know which APIs you want ;-)

Update: Changed loop variable from $a to $el when reminded by graff. Tks.

But it would be better not to use "$a" as the name of the iterator variable in the "for" loop, in case "doing stuff" includes using "sort".	[reply]

Borisz, I started using XML:Twig. However facing a problem. `my $twig = XML::Twig->new(twig_handlers => {a'=> \&Test ); # Parse the file $twig->parsefile($XmlFile); # Handler sub routine sub Test { my ($parser, $element) = @_; # This prints element <a> along with its contents to some out +put file $element->print(\OP); # However What I really want done over here is have element <a> a +long with its subelements and text be copied to another variable inst +ead of being printed on screen }` [download] Problem*: What I really want done over here is have element along with its subelements and text be copied to another variable instead of being printed on screen Something like $ElementA .= $element->print; Pls advice. Thanks,	[reply] [d/l]

something like `$ElementA .= $element->sprint;`?	[reply] [d/l]

Thanks Mirod. This worked. I am still trying to get used to this response method. Didnt realise that someone replied ot my old posts. Wish there was a way to notify by email when someone replies to your posts. Later	[reply]

In your User Settings you can turn on "msg me when there's a reply to one of my posts". (update: Of course, this post might be pointless if you don't check old posts)	[reply]
