QxmlSimpleReader can't handle external entity reference file over 1k

XMLWordPrintable

      If a xml file uses external entity reference to a file, the QXmlSimpleReader uses 1k buffer to read the content. This brings a sudden stop of parsing if the file size is over 1k.
      The problematic code is in qxml.cpp: 

                                      if (ret) {
                                    QString xmlRefString = ret->data(); //this function returns maximum 1k data
                                    delete ret;
                                    if (!stripTextDecl(xmlRefString)) {
                                        reportParseError(QLatin1String(XMLERR_ERRORINTEXTDECL));
                                        return false;
                                    }
                                    if (!insertXmlRef(xmlRefString, reference, false))
                                        return false;
                                    skipIt = false;
