Get DOM variable "innerHTML"

[taaraka]

Hi all,

At first thank you Kirix for this great library!

I was trying to get document.documentElement.innerHTML as a wxString, but had no success.

Code: Select all

wxDOMElement elem = m_browser->GetDOMDocument().GetDocumentElement()
wxMessageBox(elem.GetNodeName()); // shows "HTML" which is the name of document.documentElement

I tried using GetAttribute(), GetAttributeNode(), ect.
Could someone please tell me how to access the innerHTML object?

Thank you in advance,

Hello,
I found a workaround:

Code: Select all

...
#define TEMP_PATH wxT("/home/usr/webtest.temp")
...
void saveInnerHTML() {
    wxString ihtml = innerHTML(&m_browser->GetDOMDocument().GetLastChild());
    wxTextFile tfile;
    if(!wxFile::Exists(TEMP_PATH))
        tfile.Create(TEMP_PATH);
    else {
        tfile.Open(TEMP_PATH);
        tfile.Clear();
    }
    tfile.AddLine(ihtml);
    tfile.Write();
}
wxString innerHTML(wxDOMNode* node, unsigned depth = 0) {
    wxString data;
    if(node->GetNodeName()!=wxT("#comment"))
    {
        if(node->GetNodeName()==wxT("#text"))
            data = wxString::Format(wxT("%s"), node->GetNodeValue().c_str());
        else {
            data = wxString::Format(wxT("<%s"), node->GetNodeName().Lower().c_str());
            wxDOMNamedNodeMap map = node->GetAttributes();

            for(unsigned u = 0 ; u < map.GetLength() ; u++) {
                data += wxString::Format(wxT(" %s=\"%s\""), map.Item(u).GetNodeName(), map.Item(u).GetNodeValue());
            }
            data += wxString::Format(wxT(">%s"), node->GetNodeValue().c_str());
        }
        wxDOMNodeList lst = node->GetChildNodes();
        for(unsigned u = 0 ; u < lst.GetLength() ; u++) {
            wxDOMElement elem = lst.Item(u);
            data += innerHTML(&lst.Item(u), depth+1);
        }
        if(node->GetNodeName()!=wxT("#text"))
            data += wxString::Format(wxT("</%s>\n"), node->GetNodeName().Lower().c_str());
    }
    return data;
}
...

Would be much easier if I could access innerHTML, but still great library! Thank you,
