How to add element using XML::LibXML

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

Hello everybody, I need some help because I would like to add new elements to an XML file using XML::LibXML. But I don't know how to do it. Can you please help me? If you can please give an example, it will help me to understand.

So here the original data

__DATA__
<opt>
   <item id="table 1">
      <pool>1</pool>
      <description>Lux</description>
   </item>
</opt>

I want to add new elements what you can see below (table 2)

__DATA__
<opt>
   <item id="table 1">
      <pool>1</pool>
      <description>Lux</description>
   </item>
   
   <item id="table 2">
      <pool>1</pool>
      <description>Lux</description>
   </item>
</opt>

Thanks in advance

Mana

Some indication of what you have tried, documentation you don't understand, etc. would be helpful. Here is CPAN's XML::LibXML Documentation. I suggest looking at the Document, Node and Element modules first; then other modules as necessary (e.g. cross-referenced from another module). In addition, here's W3C's XPath Specification which you should also find useful. I believe there may be a Perl interface to this; I don't have details (as I've only ever used XPath directly in this situation). In my opinion, your learning curve in this area would be best served by having a go at writing this from the documentation then asking more specific questions if you run into difficulties. I'll be happy to provide further assistance with any problems you run into. Regards, PN5	[reply]
