我正在搜索一个他真的很喜欢regexp的人。

看看这个HTML代码：

                <div class="market_sortable_column"><span class="market_listing_header_namespacer"></span>NAME<span class="market_sort_arrow" style="display:none;"> ?</span></div>
    </div>

我需要这部分:(粗体）

$ 0.03 美元

我每次都需要它时都需要它

从以下开始：＆lt; span style =＆＃34; color：white＆＃34;＆gt; AND＆lt; /跨度＆GT;

有人知道给我一个提示吗？

亲切的问候，弗雷迪
