Re: iterating NodeList::iterator gives "Text" nodes

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

The text nodes contain the white space between the tags. If you use
  document.write_to_file("file.txt");
instead of
  document.write_to_file_formatted("file.txt");
no white space is added, and there are no text nodes.

I don't think there is any documentation that explains the inheritance hierarchy. Actually I don't think there is much to explain. The inheritance hierarchy has no deeper meaning. It does not correspond to the structure of an xml document. I think it's mostly an attempt to group node types that have something in common.

Hello. I have this code and it generate some xml like this:

<?xml version="1.0" encoding="UTF-8"?>

<Scenario>

  <A/>

  <B/>

  <C/>

</Scenario>

When i want to obtain all the childs Elements (A, B, C) i use a list in this way

xmlpp::Node::NodeList list = rootNode->get_children();

for (xmlpp::Node::NodeList::iterator cur = list.begin(); cur != list.end(); ++cur)

{

cout<<(*cur)->get_name()<<endl;

}

when i obtain the list:

text

A

text

B

text

C

text

Why has it TextNodes interleaved with the Nodes i want ?

I dont understand very well the inheritance hierarchy of node types (https://developer.gnome.org/libxml++/stable/classxmlpp_1_1Node.html):

• xmlpp::Node:
  • xmlpp::Attribute
  • xmlpp::ContentNode
    • xmlpp::CdataNode
    • xmlpp::CommentNode
    • xmlpp::ProcessingInstructionNode
    • xmlpp::TextNode
  • xmlpp::Element
  • xmlpp::EntityReference

  
  

  is there some documentation that explains better inheritance hierarchy of node types and when is used each?

  
  

  Thank you very much for your time !!!
