如何用C语言实现解析HTML文档

Answer 1

参考下面代码：
#include <stdio.h>
#include <streamhtmlparser/htmlparser.h>
int main(void)
{
unsigned int getchar_ret;
htmlparser_ctx *parser = htmlparser_new();
while ((getchar_ret = getchar()) != EOF) {
char c = (char)getchar_ret;
/* If we received a '$' character, we output the current tag and attribute
* * name to stdout. */
if (c == '$') {
printf("[[ ");
if (htmlparser_tag(parser)) printf("tag=%s ", htmlparser_tag(parser));
if (htmlparser_attr(parser)) printf("attr=%s ", htmlparser_attr(parser));
printf("]]");
/* If we read any other character, we pass it to the parser and echo it to
* * stdout. */
} else {
htmlparser_parse_chr(parser, c);
putchar(c);
}
}
}
