Javascript 从大html（REGEXP）中获取小字符串

我在找一个他对regexp很在行的人

请看以下html代码：

<div class="market_listing_table_header">
        <div class="market_listing_right_cell market_listing_their_price market_sortable_column">PRICE<span class="market_sort_arrow" style="display:none;"> ?</span></div>
        <div class="market_listing_right_cell market_listing_num_listings market_sortable_column">QUANTITY<span class="market_sort_arrow" style="display:none;"> ?</span></div>
                <div class="market_sortable_column"><span class="market_listing_header_namespacer"></span>NAME<span class="market_sort_arrow" style="display:none;"> ?</span></div>
    </div>

您可以使用此正则表达式：

/<span style="color:white">.*?([0-9]+(?:\.[0-9]*)?).*?<\/span>/

/.*（[0-9]+（？：\[0-9]*）？）*/

第一组将包含您想要的内容。

Magic？我什么也没看到，伙计。我看了看，什么也没看到，再说一遍，正则表达式不是我喜欢的，所以也许他真的很好的人可以看到一些东西。@adeneo，这是一个好的；）lol:D伙计们，快来吧=）现在应该有东西了！：DI根本不会对其进行RegExp—您是通过外观从Steam Marketplace提要中提取数据—因此它应该是结构化的。计算出结构并使用DOMDocument和DOMXPath查找您要查找的数据-尝试在

span

上使用给定样式进行匹配永远不会可靠：preg_match_all（'.*（[0-9]+（？：\.[0-9]*）？）*，$html，$matches）；打印（匹配项）；这不管用！我做错什么了吗？这对我没用。我每次都得到36分：哦，无论如何，谢谢你
