我有这样的:解析HTML(获取标签之间的文本/串)
<div class="ResultItem">
<table border="0" cellpadding="0" cellspacing="0" style="top: 0; left: 0; width: 100%;">
<tr>
<td class="result">
<a href="http://msdn.microsoft.com/en-us/library/system.windows.uielement.aspx" onclick="trackClick(this, '117', 'http\x3a\x2f\x2fmsdn.microsoft.com\x2fen-us\x2flibrary\x2fsystem.windows.uielement.aspx', '1');"><b>UIElement</b> Class (System.Windows)</a>
<div class="ResultDescription"><b>UIElement</b> is a base class for WPF core level implementations building on Windows Presentation Foundation (WPF) elements and basic presentation characteristics.</div>
<div class="ResultUrl">msdn.microsoft.com/en-us/library/sy<wbr><a class="wbr"></a>stem.windows.<b>uielement</b>.aspx</div>
</td>
</tr>
</table>
</div>
我想提取从<a>(grab this string)</a>
和<div class="ResultDescription">(grab data</div>
数据。我将如何做到这一点?
