Hi Guys, Problem in a nutshell: I cannot retrieve Text node data. I am very new to Perl but need to use it for a project I am involved with. I need to write an XML parser that uses DOM that plugs into the back of apache.

My environment is:
Solaris 2.6
Perl 5.6.0
Apache 1.3.12
Mod-perl 1.24
XML::Parser 2.27
XML::DOM 1.25

An example of the XML I am parsing is:

<methodCall>Level1 Text
    <Level2a>Text at Level2a</Level2a>
    <Level2b>Text at Level2b</Level2b>
</methodCall>

(In practice it will be more complex, but that is enough for now..) An exerept from my apache module code is.... (The xml arrives in $buf having been poked in over a socket) and it is all called from the handler() routine.

my $parser = new XML::DOM::Parser;
$doc = $parser->parse( $buf ) or die "Unable to parse document";
$root = $doc->getFirstChild();
scanner($root);

sub scanner
{
    my ($rt) = @_;
    my $i;
    my $nde;

    my $ndeLst = $rt->getChildNodes();
    my $numndes = $ndeLst->getLength() - 1;

    for ( $i = 0; $i < $numndes; $i++ )
    {
        $nde = $ndeLst->item( $i );

        if ($nde->getNodeType() == TEXT_NODE )
        {
            $log->info( $i.$nde->getNodeValue());
            print $i,"TEXT", $nde->getData();
        }

        if ($nde->getNodeType == ELEMENT_NODE)
        {
            $log->info( $i.$nde->getNodeName());
            print $i, "ELEMENT ", $nde->getNodeName(), "\n";
        }
        scanner( $nde );
    }
}

Although the output is ugly, I believe I should be able to retrieve the Elements <tags> and the text (data). What I actually get is:

0TEXTLevel1 Text
        1ELEMENT Level2a
2TEXT
        3ELEMENT Level2b

The text elements seem to be lots of white space. I don't think you have to worry about casting in perl so I don't understand why I cannot retrieve the textual data. I do get the first level though. Incidently calling a $root->toString() prints everything so I know it is getting into the tree ok. I would greatly appreciate any advice from you perl gurus out there as I have spent many hours on this without any results !

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
