Getting the document from the cache

As we discussed with David, returning a QString and using the encoding of
the rendered document. The conversion of QDataStream->QString is with the
help of a QTextStream and QByteArray instead of a temp file. But here is
the diff from kde-cvs:

+QString KHTMLPart::documentSource() const
+{
+  QString sourceStr;    
+  if ( !( m_url.isLocalFile() ) &&
KHTMLPageCache::self()->isComplete( d->m_cacheId ) )
+  {
+     QByteArray sourceArray;
+     QDataStream dataStream( sourceArray, IO_WriteOnly );
+     KHTMLPageCache::self()->saveData( d->m_cacheId, &dataStream );
+     QTextStream stream( sourceArray, IO_ReadOnly );
+     stream.setCodec( QTextCodec::codecForName( encoding().latin1() ) );
+     sourceStr = stream.read();
+  } else
+  {
+    QString tmpFile;
+    if( KIO::NetAccess::download( m_url, tmpFile, NULL ) )
+    {
+      QFile f( tmpFile );
+      if ( f.open( IO_ReadOnly ) )
+      {
+        QTextStream stream( &f );
+        stream.setCodec( QTextCodec::codecForName( encoding().latin1() ) );
+        sourceStr = stream.read();
+        f.close();
+      }
+      KIO::NetAccess::removeTempFile( tmpFile );
+    }  
+  }
+
+  return sourceStr;
+}
