Iterating through all nodes and attributes of a wxXmlDocument

Hi,

 

It's been a while since I had to recurse anything, but I can't see how to do
this. I'm trying to construct a wxString that represents the text content of
a class derived from wxXmlDocument. Here's what I have:

 

wxString MyDerivedXMLDocClass::GetTextContent()

              {

                             wxString result = wxEmptyString;

                             wxXmlNode* const root = this->GetRoot();

 

                             if (root == nullptr)

                             {

                                           return wxEmptyString;

                             }

 

                             return GetNodeText(root);

}

 

              wxString MyDerivedXMLDocClass::GetNodeText(wxXmlNode * myNode)

              {

                             wxString result = wxEmptyString;

                             

                             if (myNode->GetType() == wxXML_ELEMENT_NODE)

                             {

                                           result = myNode->GetName();

 

                                           // Get all attributes

                                           for (const wxXmlAttribute*
attribute = myNode->GetAttributes(); attribute != NULL;
attribute->GetNext())

                                           {

                                                          result +=
attribute->GetName() + attribute->GetValue() + "\n";

                                           }

                             }

                                           else if (myNode->GetType() ==
wxXML_TEXT_NODE)

                             {

                                           result += myNode->GetContent() +
"\n";

                             }

 

for (wxXmlNode * childNode = myNode->GetChildren(); childNode != NULL;
childNode->GetNext())

{

                             result += GetNodeText(childNode);

                                           }

return result;

              }

                             

 

The code throws an exception, but I can't tell quite where as I'm a blind
programmer and the exception blows out my screen reader.

 

Any advice would be most welcome.

 

Tim
