Storing strings in XML file

Hi there,

Could someone help me with information on how to store strings of arbitrary length to the XML file and then retrieve them
into a CStdString (really std::string) object?
Also how to store arbitrary binary data in the XML files?

At the moment i have:

Code:

---

case simplexmlValueTypeString:
{
        simplexmlValueString* pp = new simplexmlValueString();
        if (data)
                pp->Set((const wchar_t*)data);
        else if (stringValue)
                pp->Set(stringValue);
        p=pp;
        break;
}

---

but that doesn't work with lengthy strings!
Any ideas

Thanks for your help
