Hi Francesco,
I briefly inform you about situation:
>> 1) after loading your doc, you need wxXml2Document::GetDTD
>> 2) inside your wxXml2DTD you'll find the wxXml2EntityDecl nodes
>> 3) for each of those node you need to use the GetContent() function and if a
>> valid filename is returned load it using wxXml2Document
>> 4) parse your original tree and replace the wxXML2_ENTITY_REF_NODE
with the root
>> of the wxXml2Document loaded at step #3
After some trial and error trying to implement your "manual" proposed
solution, I have found that steps 1,2 and 3 are not necessary. I
modified the sample code to dump all the nodes. Then I discovered that
when you include an external entity ( &name; ) the XML doc tree
contains in its place an wxXML_ENTITY_REF_NODE, having an
wxXML_ENTITY_DECL child. And this last one contains all needed
information (GetSystemID contains the URL to load). So I think that
only step 4, done on the fly, as you process the main document, is
necessary.
This is the code I added to your sample, in ParseNode(), before the else:
else if (node.GetType() == wxXML_ENTITY_REF_NODE)
{
toadd += wxString::Format(_T(", NodeType=%d, Name='%s'"),
node.GetType(), node.GetName());
}
else if (node.GetType() == wxXML_ENTITY_DECL)
{
wxXml2EntityDecl* pNode = (wxXml2EntityDecl*)&node;
toadd += wxString::Format(_T(", NodeType=%d, Name='%s',
SystemID='%s'\n"),
node.GetType(), pNode->GetSystemID() );
}
To be continued ...
Regards,
Cecilio
