小编yan*_*nis的帖子

我一直在尝试以与wiki标签类似的方式捕获代码块:

{{code:
      code goes here
   }}

示例代码如下所示,

$strings = array('AbCd1zyZ9', 'foo!#$bar');
foreach ($strings as $testcase) {
    if (ctype_alnum($testcase)) {
        echo "It is The string $testcase consists of all letters or digits.\n";
    } else {
        echo "The string $testcase does not consist of all letters or digits.\n";
    }
}

基本上我想捕捉之间的任何东西{{..}}.HTML页面中嵌入了多个这样的块.

我将不胜感激任何帮助.

我正在努力了解它的(*s)作用,我会很感激解释.

// pop pops the stack. It will panic if s is empty.
func (s *nodeStack) pop() *Node {
    i := len(*s)
    n := (*s)[i-1]
    *s = (*s)[:i-1]
    return n
}
