在Python中自定义HTML片段

Question

如果我有一个HTML Snippet，如何在python中获得如下所需的输出。

示例HTML代码段：

<td width="10" class="data1"><a class="datalink" href="m01_detail.asp?key=002396653&amp;itemNumber=0">&gt;</a></td>

          <td class="data1"><a class="datalink" href="m01_detail.asp?key=002396653&amp;itemNumber=0">002396653</a></td>

          <td class="data1">IMPORT EXPRESS RECYCLE</td>

          <td class="data1">961879066</td>

        <td class="data1">11/23/2016</td>  

          <td class="data1"></td>        <!--SARA-->

          <td class="data1" align="center">CN</td>

          <td class="data1" align="center">PVG</td>

输出：

961879066 | CN

到目前为止

我的代码：

    def reading():
    with open("C:\\Users\\John\\Desktop\\test.txt") as f:
        for lines in f.readlines():
            line = lines.replace("\t","").strip()
            print (line)

    f.close()

    reading()

谢谢，

您可以尝试以下代码来获取所需的输出：

import lxml.html

html = lxml.html.fromstring("""<td width="10" class="data1"><a class="datalink" href="m01_detail.asp?key=002396653&amp;itemNumber=0">&gt;</a></td>
<td class="data1"><a class="datalink" href="m01_detail.asp?key=002396653&amp;itemNumber=0">002396653</a></td>
<td class="data1">IMPORT EXPRESS RECYCLE</td>
<td class="data1">961879066</td>
<td class="data1">11/23/2016</td>
<td class="data1"></td>        <!--SARA-->
<td class="data1" align="center">CN</td>
<td class="data1" align="center">PVG</td>""")

output = html.xpath('concat(//td[4], "|", //td[7])')
print(output)  # '961879066|CN'

将原始HTML代码传递给html变量
