in reply to XML Parse, Spanish Elements

Hi Senik,
Personnally I'm not such a big fan of XML::Simple since the parsing into different types is very unconfortable. For example if a node contains one subnode, the subnode is a hash element in the node itself, with nore children it becomes an array..this is just an example, but is just to show that the parsetree is very difficult to navigate.
Myself I rather use XML::XPath. Here you can use xpath queries to navigate to the nodes you want and the result is very straightforward.
for you this would become something like :

use XML::XPath;
use XML::XPath::XMLParser;
    
my $xp = XML::XPath->new(filename => 'test.xhtml');
my $nodeset = $xp->find('/noticias/noticia');
    
foreach my $noticia ($nodeset->get_nodelist) {
    my ($title,$fulltext,$date,$time) = 
        (   $noticia->find('titulo')->string_value,
            $noticia->find('texto')->string_value,
            $noticia->find('fecha')->string_value,
            $noticia->find('hora')->string_value
         )
}

Hope this helps you, it saved my life more than once :)

You can use use the argument ForeArray to overcome that problem:
my $xs = new XML::Simple(ForceArray => 1); Now all elements are read as an array.

Hi jbrugger, Does that also mean that it will return an array of arrays of arrays....?
The downside of something like that is that you would have to use $xml->[3]->[3]->[1]->[2] structures to reference nodes from your XML file. So you have to use you knowledge about the structure of the XML file to be able to reference nodes. That feels unconfortable to me at least.
The nice thing about XML::XPath is that you can use full xpath expressions like /document//element_somwhere[@att="val"]/../next-sibbling or anything like that.

before this starts sounding like a sales-pitch for XML::XPath, I think users should just use what feels most confortable.

From the docs:


ForceArray => 1

    <opt>
      <name>value</name>
    </opt>

would parse to this:

    {
      'name' => [
                  'value'
                ]
    }

instead of this (the default):

    {
      'name' => 'value'
    }
