Question

I am trying to read tags from XML using LibXML. I can print all the tags; however, for some reason it also prints “text” tag which is not part of my XML. Anyone can explain to me what causes this behavior? Any work around? If next time I have an XML tag with a “text” tag, then how can I distinguish that “text” tag from the extra “text” tag that is generated by LibXML?

Here’s my XML file:

<?xml version="1.0"?>
<log>
<logentry
   revision="935">
<author>darwin</author>
<date>2011-06-28T01:00:18.997106Z</date>
<msg>reintegrate branch</msg>
</logentry>
<logentry
   revision="931">
<author>darwin</author>
<date>2011-06-21T22:15:01.881607Z</date>
<msg>reintegrate branch</msg>
</logentry>
</log>

I read the XML using the following code:

my $parser = XML::LibXML->new();
my $doc = $parser->parse_string($svnInfo);
my $root = $doc->getDocumentElement();
my @nodes=$root->childNodes();

foreach my $child(@nodes) {
        my $name = $child -> nodeName();
        my @atts = $child -> getAttributes();
        print "\n${name} (";

        print ")\n";
}

This is my output:

text ()

logentry ()

text ()

logentry ()

text ()

Thanks for the help.

Try adding $parser->keep_blanks(0) before my $doc = $parser->parse_string($svnInfo);

EDIT changed no_blanks to keep_blanks
