    No thats not my problem.

    After replacing my code with the code wat u give me to replace with, the following is the table entries now.

    The following table for Question entries

    QNo | Question | QueLocLang | Board | Subject | Chapter | PageNo

    4724 | What is Qt? | NULL | Tamil Nadu | EnglishI | 1 | 1

    4725 | Who is Sachin? | NULL | Tamil Nadu | EnglishI | 1 | 1

    The table entries for Answers is,
    More than one time it is entering like the following

    APNo | Statement1 | Statement2 | Option1 | QNo

    80563 | | NULL | | 4724

    80564 | | NULL | | 4724

    80565 | | NULL | | 4724

    80566 | | NULL | | 4725

    80567 | | NULL | | 4725

    80568 | | NULL | | 4725

    The actual Answer table should be like,

    APNo | Statement1 | Statement2 | Option1 | QNo

    80563 | Qt is a | NULL | cross platform application framework | 4724

    80564 | | is sachin | A famous crickter | 4725

    But i am not getting like this. I am just getting the empty values for stmt1,option.

      Instead of the following code

      @
      int mainForm::parseOption(int ind,QString option, QString &stmt1, QString &phrase)
      {
      QTextStream cout(stdout, QIODevice::WriteOnly);
      int j = 0;
      int index = ind;
      cout<<"index---\n"<<index<<endl;
      cout<<"311 : parseOption : "<<option<<endl;
      cout<<"option[index]--\n"<<option[index]<<endl;
      while(option[index] != '|')
      {
      stmt1[j] = option[index];
      cout<<"stmt1[j]\n"<<stmt1<<endl;
      if(option[index]=='\0')
      {
      cout<<"option[index]-----\n"<<option[index]<<endl;
      stmt1[j] = '\0';
      option[0] = '\0';
      return -1;
      // return (index);
      }
      index++;
      j++;
      }
      stmt1[j] = '\0';
      stmt1=stmt1.replace( "{sub}","<sub>");
      stmt1=stmt1.replace( "{/sub}","</sub>" );

      while(option[index] != '\')
      {
      phrase[j] = option[index];
      index++;
      j++;
      }

      cout<<"425 : "<<stmt1<<endl;
      j = 0;
      index++;
      cout<<"option[index]-->\n"<<option[index]<<endl;
      phrase=phrase.replace( "{sub}","<sub>" );
      phrase=phrase.replace( "{sub}","<sub>" );
      cout<<"Phrase value"<<phrase<<endl;
      phrase[j] = '\0';
      cout<<"436 : "<<phrase<<endl;

      return (index + 1);

      }
      @

      I added the code u asked me to add

      @

      1.  int pos1 = option.indexOf('|');
        
      2.  if (pos1 != -1)
        
      3.  {
        
      4.    stmt1 = option.left(pos1);
        
      5.      int pos2 = option.indexOf('\\', pos1);
        
      6.      if (pos2 != -1)
        
      7.      {
        
      8.          phrase = option.mid(pos1, pos2 - pos1);
        
      9.      }
        
      10. else
        
      11. {
      12. // there is no '|' symbol in option
      13.  }

        I've already checked my code and it works fine (actually, you can change line 9 with phrase = option.mid(pos1 + 1, pos2 - pos1); to remove leading '|').

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

          I tried by that too phrase = option.mid(pos1 + 1, pos2 – pos1); bt nw th answer table is not get updated.
          i.e the Questions are entering to the database, but the answers are not entering to the database in answer table.

            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);

            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
                                      cross platform appln framework

                                      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
                                      stmt1temp
                                      .
                                      stmt1
                                      .
                                      phrasetemp
                                      cross platform appln framework
                                      phrase
                                      cross platform appln framework

                                        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

                                          @
                                          return (index);
                                          @
                                          Also in the case SHORT:
                                          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.
