Parsing XML

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks!

I have this test script trying to use XML::Twig to extract as an example the "CustomerId" from the XML. I can not understand why I am getting "Couldn't open" - "No such file or directory" erros when the file if right there.
Here is the sample code and thanks for helping!

#!/usr/bin/perl

use strict;
use warnings;
use XML::Twig;
use Data::Dumper;


my $xml =  qq|<?xml version="1.0" encoding="ISO-8859-1"?>
<CustDetails>
<CustName>Unix</CustName>
<CustomerId>999</CustomerId>
<Age>28</Age>
</CustDetails>
|;

my $t= XML::Twig->new( twig_handlers => 
                           { 'CustDetails/CustomerId' => sub { $_->pri
+nt } }
                       )
                  ->parsefile($xml);
warn Dumper $t;

`->parsefile` [download] expects a filename, but you're passing it raw XML already. Most likely, `->parse(...)` [download] will work better for you...	[reply] [d/l] [select]

Using "->parse(...)" got me this "<CustomerId>999</CustomerId>" Is there a way to get just the value "999" directly? Thanks!	[reply]

Yes, and that way is documented in the XML::Twig documentation. Maybe using `->print` is the wrong method here. Most likely, you will find the appropriate method to get at the text of a node in the documentation.	[reply] [d/l]

It says parsefile not parsestring. A file is expected. Neil Watson watson-wilson.ca	[reply]
