我有4段/a/b/c/ # nothing, pathname ends with the dir 'c'
c:\windows\ # nothing, pathname ends with the dir 'windows'
c:hello.txt # matches potential filename 'hello.txt'
~it_s_me/.bashrc # matches potential filename '.bashrc'
c:\windows\system32 # matches potential filename 'system32', except
# that is obviously a dir. os.path.is_dir()
# should be used to tell us for sure
。我需要选择每个段落，除了在这个结构上留下前两段：
<p>我在下面写了css，
<div class="right">
<a></a>
<p>heading</p>
<p></p>
<p style="margin-bottom:6.0pt;vertical-align:baseline;">
<span style="color:#2F2F2F ;">hi....Each day the world meets your expectations. It's no secret that your perspective shapes your experience.
What's remarkable, however, is how belief builds awareness; and how with every insight, doors open, new futures unfold
and once-only-dreamed-of possibilities become everyday realities.</span>
</p>

您可以改用:nth-of-type，试试这个：
.right p:nth-of-type(n+3) {
background:yellow;
}<div class="right">
<a href="#">I'm a link</a>
<p>heading</p>
<p>empty p</p>
<p style="margin-bottom:6.0pt;vertical-align:baseline;">

您可以使用:nth-child或:nth-type-of伪类来实现结果：
.right p:nth-of-type(n + 3) {
background: green;
}<div class="right">
<a href="">a link</a>
<p>heading</p>
<p>other p</p>
