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:
An example of the XML I am parsing is:
<Level2a>Text at Level2a</Level2a>
<Level2b>Text at Level2b</Level2b>
(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 = $doc->getFirstChild();
my ($rt) = @_;
my $ndeLst = $rt->getChildNodes();
my $numndes = $ndeLst->getLength() - 1;
for ( $i = 0; $i < $numndes; $i++ )
$nde = $ndeLst->item( $i );
if ($nde->getNodeType() == TEXT_NODE )
print $i,"TEXT", $nde->getData();
if ($nde->getNodeType == ELEMENT_NODE)
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:
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 !
