我有一个HTML文档,其中包含非常简单的表格
<table>
<tr><th>Country</th><th>Date</th></tr>
<tr>
<td><b><a href="/calendar/?region=BE">Belgium</a></b></td>
<td align="right"><a href="/date/04-20/">20 April</a> <a href="/year/2001/">2001</a></td>
<td>(original release)</td>
</tr>
<tr>
<td><b><a href="/calendar/?region=BE">Belgium</a></b></td>
<td align="right"><a href="/date/04-25/">25 April</a> <a href="/year/2001/">2001</a></td>
<td></td>
</tr>
<tr>
<td><b><a href="/calendar/?region=FR">France</a></b></td>
<td align="right"><a href="/date/04-27/">27 April</a> <a href="/year/2001/">2001</a></td>
<td></td>
</tr>
<tr>
<td><b><a href="/calendar/?region=CH">Switzerland</a></b></td>
<td align="right"><a href="/date/05-25/">25 May</a> <a href="/year/2001/">2001</a></td>
<td>(French speaking region)</td>
</tr>
<tr>
<td><b><a href="/calendar/?region=CZ">Czech Republic</a></b></td>
<td align="right"><a href="/date/07-06/">6 July</a> <a href="/year/2001/">2001</a></td>
<td>(International Film Festival)</td>
</tr>
</table>
前两列很容易解析:
document.search("a[@href*=calendar]").each { |country| countries << country.inner_text }
document.search("td[@align*=right]").each { |date| dates << date.inner_text }
但我从第3栏查找值时遇到麻烦。我需要所有这些数组,包括空白数组。我怎么能这样做?
答案 0 :(得分:0)
回答我自己的问题:
document.search("td[@align*=right]").each { |comment| comments << comment.next.next.inner_text }
