QString EQRegExp::cap ( int  nth = 0  ) 

Returns the text captured by the nth subexpression. The entire match has index 0 and the parenthesized subexpressions have indexes starting from 1 (excluding non-capturing parentheses).

        EQRegExp rxlen("(\\d+)(?:\\s*)(cm|inch)");
        int pos = rxlen.indexIn("Length: 189cm");
        if (pos > -1) {
            QString value = rxlen.cap(1); // "189"
            QString unit = rxlen.cap(2);  // "cm"
            // ...

The order of elements matched by cap() is as follows. The first element, cap(0), is the entire matching string. Each subsequent element corresponds to the next capturing open left parentheses. Thus cap(1) is the text of the first capturing parentheses, cap(2) is the text of the second, and so on.
