我正在用 C 编写一个小程序,用于检查 HTML 文件是否具有正确的打开和关闭标签?但我有一些问题......我有一个文件,其中包含所有可能的标签,名为 tags.txt(这些只是第一个):
<a>
</a>
<abbr>
</abbr>
<area>
</area>
<aside>
</aside>
我有 htmlfile.html,我必须检查:
<!--#echo var="date" -->
<area>
</area>
<area>
</area>
其次,我想将这样的评论替换为 sysdate 之类的,格式可以,我可以做到,但是 prog 将这个文件放入
我的代码:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <time.h>
#define MAX_SIZE 512
void menu();
void check();
void datumos();
int main(int argc,char *argv[])
{
menu();
return 0;
}
void menu()
{
char menu[MAX_SIZE];
while(1 < 2)
{
printf("\npress a button:\n\n");
printf("\tFile HTML check..............:c\n");
printf("\t<!--#echo var="date" -->...........:d\n");
printf("\tExit:\tCTRL + C\n");
scanf("%s",menu);
if( strcmp(menu,"c") == 0 )
{
check();
}
else if( strcmp(menu,"d") == 0 )
{
datumos();
}
}
}
void check()
{
FILE *htmlfile;
FILE *checkfile;
htmlfile = fopen("htmlfile.html","w");
checkfile = fopen("tags.txt","r");
char line[MAX_SIZE];
char htmlline[MAX_SIZE];
char tags[189][30];
int i=0;
printf("\tcheck__1\n");
while(fgets(line,sizeof(line),checkfile) != NULL)
{
int j;
for(j=0; j<sizeof(line); ++j)
{
tags[i][j]=line[j];
}
++i;
}
printf("\tcheck__2\n");
int k=0; char htmlfiletags[MAX_SIZE][30];
while(fgets(htmlline,sizeof(htmlline),htmlfile) != NULL)
{
char currentline[sizeof(htmlline)];
int j=0;
if( currentline[j]=="<" )
{
while(currentline[j]!=">")
{
htmlfiletags[k][j]=currentline[j];
++j;
}
strcat(htmlfiletags[k][j+1],">");
++k;
}
}
printf("\tcheck__3\n");
int n;
for(n=0; n<sizeof(htmlfiletags); ++n)
{
int j; int howmanytimesnot=0;
for(j=0; j<sizeof(tags); ++j)
{
printf("\tcheck__3/1\n");
if(strcmp(htmlfiletags[n],tags[j])==0)
{
printf("\t%d\n", howmanytimesnot);
++howmanytimesnot;
}
}
printf("\tcheck__3/3\n");
if(!(howmanytimesnot<sizeof(tags)))
{
printf("\tcheck__3/4\n");
printf("the file is not wellformed");
exit (1);
}
}
printf("\tcheck__4\n");
}
void copy_file(const char *from,const char *to)
{
FILE *fr;
FILE *t;
fr = fopen(from,"r");
t = fopen(to,"w");
char line[MAX_SIZE];
char row[MAX_SIZE];
while(fgets(line,sizeof(line),fr) != NULL)
{
sscanf(line,"%s",row);
fprintf(t,"%s\n",row);
}
fclose(fr);
fclose(t);
remove("tempfile.html");
}
void datumos()
{
time_t now = time(NULL);
struct tm *t = localtime(&now);
char date_time[30];
strftime( date_time, sizeof(date_time), "%x_%X", t );
FILE *htmlfile;
FILE *tempfile;
htmlfile = fopen("htmlfile.html","r");
tempfile = fopen("tempfile.html","w");
char line[MAX_SIZE];
//char datecomment[]="<!--#echo var=date -->";
while(fgets(line,sizeof(line),htmlfile) != NULL)
{
if( strcmp(line,"<!--#echo var="date" -->") == 0 )
{
char row[40];
strcpy(row,"<!--");
strcat(row, date_time);
strcat(row,"-->");
printf("%s",row);
fputs(row,tempfile);
}
else
{
fputs(line,tempfile);
}
}
fclose(htmlfile);
fclose(tempfile);
copy_file("tempfile.html","htmlfile.html");
}
它死在这里,在内部 for 循环中,在第 200 次检查的 if 中……我不知道为什么……
int n;
for(n=0; n<sizeof(htmlfiletags); ++n)
{
int j; int howmanytimesnot=0;
for(j=0; j<sizeof(tags); ++j)
{
printf("\tcheck__3/1\n");
if(strcmp(htmlfiletags[n],tags[j])==0)
{
printf("\t%d\n", howmanytimesnot);
++howmanytimesnot;
}
}
printf("\tcheck__3/3\n");
if(!(howmanytimesnot<sizeof(tags)))
{
printf("\tcheck__3/4\n");
printf("the file is not wellformed");
exit (1);
}
}
谢谢大家的回复!!G
