    @
    QString option = "Qt is a |cross platform application framework\.";
    int pos1 = option.indexOf('|');
    if (pos1 != -1)
    {
    stmt1 = option.left(pos1);

    int pos2 = option.indexOf('\\', pos1);
    if (pos2 != -1)
    {
        phrase = option.mid(pos1, pos2 - pos1 + 1);
    }
    

    }
    else
    {
    qDebug("there is no '|' symbol in option");
    }

    qDebug("stmt1=%s, phrase=%s", qPrintable(stmt1), qPrintable(phrase));
    @

    Output: "stmt1=Qt is a , phrase=|cross platform application framework"

    Is this output correct for your task?

      The '|' and '' should not seen in the database. Otherwise the output is correct.
      But, the thing is i need the stmt2 also enter to the database.
      for eg

      |Lotus\ is our national flower.

      In the above stmt, lotus is the phrase, and is our national flower is the stmt2.
      That stmt2 is not entering in database.

      And also tried with that code, also remain the same problem, the answers are not entering into the database.

            So in my code instead of return -1, i replaced it by returning the index as return index.

            As in the switch case, in if condition i'm checking the condition as

            @
            if(option[index]=='\0')
            {
            cout<<"option[index]-----\n"<<option[index]<<endl;
            stmt1[j] = '\0';
            option[0] = '\0';
            //return -1; instead of this
            return (index); added this
            }
            @

            instead of this condition i replaced it as,

            @
            if(index!=-1) instead of this

            if((((Short *)object)->options[i])[index]!='\0') added this
            {
            query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values ("" + stmt1 + "", NULL,"" + phrase + ""," + temp2.setNum(qNo) + "," + temp2.setNum(((Short *)object)->ptno[i+1])+",1)");
            }
            @

            With the above condition what i've added it working fine.

            It is inserting into the Ques table and also in Ans table now. whether it is right or nt. Do you have any idea about this. Please tell me

              What is an "Answer table"?! We didn't speak about any insertion of data to Answer table. Check your SQL-queries for correctness.

                The answer table is where the options and stmt get parsed i.e Qt is a |Cross platform appln framework. is to be in the answer table.
                Surely i'll check the SQL-queries where i've to do the corrections.

                  First of all - print all values on the screen
                  Second - change SQL-query builder to the next:

                  @
                  query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values (?, ?, ?, ?, ?, ?)");
                  query.addBindValue(stmt1);
                  query.addBindValue(QVariant(QVariant::String)); // NULL string
                  query.addBindValue(phrase);
                  query.addBindValue(temp2.setNum(qNo));
                  query.addBindValue(temp2.setNum(((Short *)object)->ptno[i+1]));
                  query.addBindValue(1);
                  @

                    Sorry for asking you again and again, please tell me
                    Instead of the following code
                    @
                    query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values ("" + stmt1 + "", NULL,"" + phrase + ""," + temp2.setNum(qNo) + "," + temp2.setNum(((Short *)object)->ptno[i+1])+",1)");
                    @

                    I've to add this code
                    @
                    query = new QSqlQuery("insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values (?, ?, ?, ?, ?, ?)");
                    query.addBindValue(stmt1);
                    query.addBindValue(QVariant(QVariant::String)); // NULL string
                    query.addBindValue(phrase);
                    query.addBindValue(temp2.setNum(qNo));
                    query.addBindValue(temp2.setNum(((Short *)object)->ptno[i+1]));
                    query.addBindValue(1);
                    @

                    If means by adding this code it is showing the error as request for member ‘addBindValue’ in ‘query’, which is of non-class type ‘QSqlQuery

                    For printing the values on screen i already added the following code.

                    @index = parseOption(index,((Short *)object)->options[i],stmt1,phrase);
                    cout<<"index : "<<index<<"\n"<<stmt1<<"\n"<<phrase<<endl;
                    QString text11;
                    stmt1temp=stmt1;
                    cout<<"stmt1temp\n"<<stmt1<<endl;
                    stmt1=stmt1temp;
                    cout<<"stmt1\n"<<stmt1<<endl;
                    phrasetemp=phrase;
                    cout<<"phrasetemp\n"<<phrasetemp<<endl;
                    phrase=phrasetemp;
                    cout<<"phrase\n"<<phrase<<endl;@

                      1. change '.' to '->'
                      2. What is an output of cout << *?

                          1. As I can see your output doesn't contain any NULL-value. So, I think you have errors somewere else... Possibly, in SQL-table (e.g. wrong field type).
                          2. For what are you make such assignments:

                          @
                          ...
                          stmt1temp=stmt1;
                          cout<<"stmt1temp\n"<<stmt1<<endl;
                          stmt1=stmt1temp;
                          ...
                          @
                          ?

                            For eg if i am entering the answer like this.
                            Android is a |Linux-based operating system\ designed primarily for touchscreen mobile devices.

                            In the following code,
                            @
                            index = parseOption(index,((Short *)object)->options[i],stmt1,phrase);
                            cout<<"index : "<<index<<"\n"<<stmt1<<"\n"<<phrase<<endl;
                            @
                            The stmt1temp,stmt1 is considered as Android is a
                            As you know, the phrasetemp,phrase is the same Linux-based operating system
                            By the following code,

                            @
                            stmt1=parseQuestion(stmt1); // function called for replacing tilde,cape symbol to angluar brackets
                            cout<<"stmt1--\n"<<stmt1<<endl;
                            stmt2temp=parseStepNo(stmt1,i,aPNo);
                            cout<<"stmt2temp\n"<<stmt2temp<<endl;
                            cout<<"\nThis is the apno value required"<<aPNo<<endl;
                            stmt2=stmt2temp;
                            cout<<"This is STatement2 value"<<stmt2<<endl;
                            @

                            The stmt1 is taken for stmt2 i.e designed primarily for touchscreen mobile devices.
                            The assignments are mainly made for parsing the options.

                              Actually i missed some thing in the previous post

                              index : 40
                              Qt is a

                              stmt1temp
                              Qt is a
                              stmt1
                              Qt is a
                              phrasetemp
                              cross platform appln framework
                              phrase
                              cross platform appln framework

                              After this
                              text11insert into ShAnsPts(Statement1,Statement2,Option1,QNo,PointNo,CorrectNo) values ("Qt is a ", NULL,"cross platform appln framework",4816,4816,1)

                              Then,

                              index : 41
                              Qt is a

                              cross platform appln framework
                              phrase

                                Also exactly not like that. As assigning the null values in the code for stmt1 and option it will take null values in the out put i.e when printing the output as Qt is a |cross platform appln framework.
                                In the above result
                                after printing the stmt1 Qt is a after this null value is seen.

                                  Instead of returning index value as -1

                                  @
                                  return -1;

                                  I returned the index itself

                                  Instead of checking the condition for executing query for inserting into answer table,

                                  @
                                  if(index=-1)
                                  @

                                  I checked the condition,
                                  @
                                  if((((Short *)object)->options[i])[index]!='\0')
                                  @
                                  Now it is working fine and all the questions and answers are entering to the main xml file also to the database in the appropriate table.

                                  Thanks Lukas Geyer and thanks a lot Aleksey Okinchitc.
