QRegExp Extracts the Content of Online-News

The following example shows how to extract the string between <div class="yn-story-content"> and </div>.

ContentExtractor::ContentExtractor(QObject *parent)
    : QObject(parent)

    //regexp pattern
    QString escape1 = QRegExp::escape("<div class=\"yn-story-content\">");
    QString escape2 = QRegExp::escape("</div>");
    QString aPattern = escape1 + "(.*)?" + escape2;
    regExp_.setPattern ( aPattern );
    regExp_.setMinimal ( true );
void ContentExtractor::extractContent(QString text_in)
    if (regExp_.indexIn(text_in) != -1) {
        content_ = regExp_.cap(1);
        content_ = content_.trimmed();
        content_ = content_.remove('\n');
        content_ = content_.remove('\t');
