void XMLTokenizer::write( const TokenizerString &str, bool appendData )
{
    if ( !m_noErrors && appendData )
        return;
    if ( appendData ) {
        m_source.appendXML( str.toString() );

    } else {
        m_source.setData( str.toString() );
    }
    // Here will I add my code
    m_noErrors = m_reader.parseContinue();
}

Can I access the string html code with m_source.data?
