QRegExp for extracting the string between two HTML tags...

[tuthmosis]

Greetings !

Say i have <td>this is a test</td>... what would be the regexp pattern to get the string "this is a test" ?

Thanks !

Since that is such an basic question, please use our Newbie section next time, and please read the documentation on regular expression. It don't have to be the Qt one. Any basic introduction on regular expressions. (http://www.regular-expressions.info/quickstart.html and grouping)

Sorry but i had my reasons to ask... I know regexp, no need to insult me.
If i ask it's because normal regexp don't seam to be compatible with QRegExp.
For my need, the following should work.
(?<=<TH>)([a-zA-Z0-9 ])+(?=</TD>)

Applied to <TH>test</TD> ... this pattern will return <TH>test... so the backward lookup doesn't seem to be implemented.

Well you didn't ask the following in the first time!

For my need, the following should work.
(?<=<TH>)([a-zA-Z0-9 ])+(?=</TD>)

Yes, not all is implemented, but one can achieve all with some extra work.

QString str = "<TH>test</TD> foo <TH>bar</TD>";
    QRegExp rx("<TH>([a-zA-Z0-9 ]+)</TD>");
    QStringList list;
    int pos = 0;
    while ((pos = rx.indexIn(str, pos)) != -1)
    {
        list << rx.cap(1);
        pos += rx.matchedLength();
    }
    qWarning() << list; // ("test", "bar")

QString str = "<TH>test</TD> foo <TH>bar</TD>";
    QRegExp rx("<TH>([a-zA-Z0-9 ]+)</TD>");
    QStringList list;
    int pos = 0;
    while ((pos = rx.indexIn(str, pos)) != -1)
    {
        list << rx.cap(1);
        pos += rx.matchedLength();
    }
    qWarning() << list; // ("test", "bar")
