Can I called it as a Parser

[rupali bhore]

Hello Sir/ Mam,

I am trying to optimize time require for XML parsing. What ever little knowledge I have about XML parsing according to that I did one program (in which it is only fetching data between tags by simple file handling concepts and giving me much optimize output as compare to pugi XML. I tried it for filesize 1MB ) So my question is can I called it as a complete XML parser?? Or what are those requirements which should be fulfilled by one XML parser??Cause I think this might be done some where before.

this is my code
***********************************************************************

#include<stdio.h>
#include<iostream.h>
#include<string.h>
#include<time.h>


void main()
{

clock_t start,end;
double cpu_time_used;
int i;
start = clock();

FILE *fp,*wfp;
char text[300],c,stk[5][5],tempTag[10],value[20],closeTag,flag,fClose,sStart,tagNo=1;
int j,n,top=-1;

fp=fopen("xmll.txt","r");
wfp=fopen("xml.txt","w");
while(strlen(fgets(text,300,fp))!=0)
{
closeTag=0; flag=0;
for(i=0;i<strlen(text);i++)
{
if(text[i]=='>')
{
closeTag++;
if(flag==0)
{
fClose=i;
flag=1;
}
}
// printf("\nFlag = %d \t text[i]= %c \t i = %d",flag,text[i],i);
if(flag==1 && text[i]=='<')
{
sStart=i;
}
}
if(closeTag==2)
{
/* printf("\n%s",text);
printf("\tfclose = %d",fClose);
printf("\t sStart = %d",sStart);*/
j=0;
for(i=(fClose+1);i<sStart;i++)
{
value[j]=text[i];
j++;
}
value[j]='\0';




switch(tagNo){
case 1: fputs(value,wfp);fputs("\n",wfp);tagNo++;break;
case 2: fputs(value,wfp);fputs("\n",wfp);tagNo++;break;
case 3: fputs(value,wfp);fputs("\n",wfp);tagNo++;break;
case 4: fputs(value,wfp);fputs("\n",wfp);tagNo++;break;
case 5: fputs(value,wfp);fputs("\n",wfp);tagNo++;break;
case 6: fputs(value,wfp);fputs("\n",wfp);tagNo=1;fputs("\n\n",wfp);;break;
}
}


}

end=clock();
cpu_time_used=((double) (end-start))/CLOCKS_PER_SEC;

cout<<cpu_time_used;

}
