Question about XML::DOM::Lite

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

I am using the cpan XML-DOM-Lite library version 0.08 to create an xml document. The following is the code and output.

my $dc = XML::DOM::Lite::Document->new();
my $root = $dc->createElement("xml");

my $elem = $dc->createElement("A");
$elem->setAttribute("B", "C");
$root->appendChild($elem);
$dc->appendChild($root);

print $dc->xml();


Output:
=======
<xml>
  <A B="C" />
</xml>
[download]

Instead of having "B" defined as an attribute, I want "B" to be defined as a separate tagname, with "C" defined as a text. Is this xml output possible?


Desired output:
===============
<xml>
  <A><B> C </B></A>
</xml>

I made the following changes to the code, and it returned an error message.


my $dc = XML::DOM::Lite::Document->new();
my $root = $dc->createElement("xml");

my $elem = $dc->createElement("A");
my $elem2 = $dc->createElement("B");    # Added
$elem2->createTextNode("C");        # Added
$elem->appendChild($elem2);        # Added
$root->appendChild($elem);
$dc->appendChild($root);

createTextNode is a DOCUMENT method, so the object used should be $dc, not $elem2. It returns a NODE object that you can use to attach as a child node. "XML is like violence: if it doesn't solve your problem, use more."	[reply]

I usually use XML::XSH2 for XML manipulation: `create xml ; insert element A into xml ; insert element B into xml/A ; cd xml/A/B ; insert text "C" into . ;` [download]	[reply] [d/l]
