问题描述

我正在尝试从具有我所知道的特定ID的表中获取数据.由于某种原因，代码不断给我无"结果.

I'm trying to get the data from a table with a specific ID which I know.For some reason, the code keeps giving me a None result.

根据我要解析的HTML代码:

From the HTML code I'm trying to parse:

<table cellspacing="0" cellpadding="3" border="0" id="ctl00_SPWebPartManager1_g_c001c0d9_0cb8_4b0f_b75a_7cc3b6f7d790_ctl00_HistoryData1_gridHistoryData_DataGrid1" style="width:100%;border-collapse:collapse;">
    <tr class="gridHeader" valign="top">
        <td class="titleGridRegNoB" align="center" valign="top"><span dir=RTL>שווי שוק (אלפי ש"ח)</span></td>
        <td class="titleGridReg" align="center" valign="top">הון רשום למסחר</td>
        <td class="titleGridReg" align="center" valign="top">שער נמוך</td><td class="titleGridReg" align="center" valign="top">שער גבוה</td>
        <td class="titleGridReg" align="center" valign="top">שער בסיס</td>
        <td class="titleGridReg" align="center" valign="top">שער פתיחה</td><td class="titleGridReg" align="center" valign="top"><span dir="rtl">שער נעילה (באגורות)</span></td>
        <td class="titleGridReg" align="center" valign="top">שער נעילה מתואם</td><td class="titleGridReg" align="center" valign="top">תאריך</td>
    </tr>
    <tr onmouseover="this.style.backgroundColor='#FDF1D7'" onmouseout="this.style.backgroundColor='#ffffff'">

...等等

我的代码:

html = br.response().read()
soup = BeautifulSoup(html)

table = soup.find(lambda tag: tag.name=='table' and tag.has_key('id') and tag['id']=="ctl00_SPWebPartManager1_g_c001c0d9_0cb8_4b0f_b75a_7cc3b6f7d790_ctl00_HistoryData1_gridHistoryData_DataGrid1")
rows = table.findAll(lambda tag: tag.name=='tr')

In [100]: print table
None

推荐答案

来自文档:

table = soup.find('table', id="ctl00_SPWebPartManager1_g_c001c0d9_0cb8_4b0f_b75a_7cc3b6f7d790_ctl00_HistoryData1_gridHistoryData_DataGrid1")

行行:

rows = table.findAll('tr')

对于编码问题，请尝试从utf-8解码，然后重新编码.

For the encoding problem, try decoding it from utf-8, and re-encode it.

html = br.response().read().decode('utf-8')
soup = BeautifulSoup(html.encode('utf-8'))
