各位老大：
我现在希望用C写一个解析html的程序，我解析的是http传过来的html,如下所示：
<html><head><style type=text/css>td {font-size:12px;text-align:center;line-height:normal;}</style><TITLE>Phone V1.43.021 </TITLE><script language=javascript>function selchange_iptype(){var ival;ival =

这是我抓包抓来的，请大家看看，我的目的是得到其中的数据，比如value=192.168.0.123我要的就是这个IP地址，和前面<td>IP</td>里的IP，以便我能知道这是一个什么值，然后再调用其他函数用这个值，希望各位大哥能给我个程序或者办法取道这个值，并知道它是个什么值。

int main(void)
{
char str[20];
char str1[20];
int i=0,t=0 ;
while(scanf("%s ",str)!=EOF)//怎么读怎么处理是你的事，这里是用文本读，将上面的html存作为文本利用dos重定向 test.exe < 1.txt
{
if(strlen(str)>=13)
if(!strncmp(str,"value=",6))
{
i=0 ;
while((str1[i]=str[6+i])!=0)i++;
str1[i+1]=0 ;
i=0,t=0 ;
while(str1[i])
{
if(str1[i]=='.')t++;
i++;
}
if(t==3)printf("%s\n",str1);//输出IP
}
}
return 0;
}
随手写一个，未调试，自己看着改吧

假如你会用THTML之类的控件就更简单了

谢谢大哥指教，我当研读，有不懂之处，还望再加指教。

k哥：
请您指教一下我如何得到页面上的全部数据，不光是IP，其他的也要，还有就是我不光得到他们，还要知道他们是什么，比如我得到了192.168.0.123,我还要知道它是ip,我好去调其他的函数处理它。
