If the styles are consistent, then you can loop over all divs in the document and filter them by style.
如果样式一致，那么您可以遍历文档中的所有 div 并按样式过滤它们。
var divs = document.getElementsById("div");
for (var i = 0; i < divs.length; i++) {
var div = divs[i];
// skip the current div if its styles are wrong
if (div.style.cssFloat !== "left"
|| div.style.marginTop !== "10px"
|| div.style.fontFamily !== "Verdana"
|| div.style.fontSize !== "13px"
|| div.style.color !== "#404040") continue;
var text = div.innerText || div.textContent;
// do something with text
}

You may use the content of styletag if no idor classis given there like:
style如果没有id或class在那里给出，您可以使用标签的内容，例如：
include('simple_html_dom.php');
$html = file_get_html('http://www.mysite.com/');
foreach($html->find('div[style="float: left; margin-top: 10px; font-family: Verdana; font-size: 13px; color: #404040;"]') as $e)
echo $e->innertext;

You could probably try to match some of their parents (which have classor idset), then traverse the DOM to the child you want.
您可能会尝试匹配他们的一些父级（已设置class或已id设置），然后将 DOM 遍历到您想要的子级。

Thanks to all. I depends on simple_html_domtoo much, Ben Blank give me a good way.
And I also tried php regular-expression to match the div by myself.
谢谢大家。我simple_html_dom太依赖了，Ben Blank 给我一个好方法。而且我还尝试了 php 正则表达式来自己匹配 div。
preg_match_all('/<div.*(style="float: left; margin-top: 10px; font-family: Verdana; font-size: 13px; color: #404040;").*>([\d\D]*)<\/div>/iU',$html,$match);
print_r($match);
