Re: QXmlStreamReader

Thank you. That works very well. Except when the data read becomes more
complex, as in this real world example:

<ar><k>Bristle</k>
Bristle \Bris&quot;tle\, v. t. [imp. &amp; p. p. {Bristled}; p. pr. &amp;
vb.
   n. {Bristling}.]
   1. To erect the bristles of; to cause to stand up, as the
      bristles of an angry hog; -- sometimes with up.
      [1913 Webster]

            Now for the bare-picked bone of majesty
            Doth dogged war bristle his angry crest. --Shak.
      [1913 Webster]

            Boy, bristle thy courage up.          --Shak.
      [1913 Webster]

   2. To fix a bristle to; as, to bristle a thread.
      [1913 Webster]</ar>

As you can see the text contains &quot; and &amp;. When reading with 

if ( reader.isCharacters() )
   qDebug() << reader.text().toString();

everything before the last such character (the second &amp; in this case)
gets chopped of.

The above is from an xdxf version of an old edition of Webster's dictionary.
Since it has 200,655 entries, I was hoping that QXmlStreamReader would be
faster than QDomDocument, but that does not really seem to be the case.

Anyway, thanks again for your help.

If you modify the code to look like:

QString data;
while ( !( reader.isEndElement() && reader.name() == "ar" ) )
{
     // should be two children
     reader.readNext();
     if ( reader.isStartElement() && reader.name() == "k" )
         qDebug() << reader.readElementText();
     else if ( reader.isCharacters() || reader.isEntityReference() )
         data += reader.text().toString();
}

qDebug() << data;

Then you'll see all of the data retrieved with the entities substituted.
