Xpath如何获取标签中的所有文本

Question

I have this html code:

<div id="m0" style="visibility:visible; display:block;">
 <table class="fl">
  <tr bgcolor="white"><td class="v px3"></td>
   <td class="ch">
     <a title="Id: NetViet" class="A3">NetViet</a></td>
   </tr>

<div id="m1" style="visibility:visible; display:block;">
 <table class="fl">
  <td class="ch">
   <A class="A3" title="Id: Kino Polska Muzyka" HREF="http://www.kinopolskamuzyka.pl/" TARGET="_blank">Kino Polska Muzyka</A>
 </tr>
  <td class="ch">
   <i>HBO3 HD</i></td>
 </tr>
  <td class="ch"> Faktura</td>
 </tr>

My xpath is : tree.xpath('//div[@id="%s"]/table[@class= "fl"]/tr/td[@class="ch"]/a/text()'%div)

but it does not give me all the channels. I want to get all text in <td class="ch"> , the result that i want is:

[['NetViet'],['Kino Polska Muzyka','HB03','Faktura']]

Any idea? Thanks in advance.

Answer 1

除了弄乱了html结构之外，还要从xpath中删除“ tr”和“ a”节点，因为并非每个“ td”都被它们包围。

Answer 2

Why not use css selectors to target td tag elements with that class? For this type of selection is it likely faster than xpath.

from bs4 import BeautifulSoup as bs

html = '''
<div id="m0" style="visibility:visible; display:block;">
 <table class="fl">
  <tr bgcolor="white"><td class="v px3"></td>
   <td class="ch">
     <a title="Id: NetViet" class="A3">NetViet</a></td>
   </tr>

<div id="m1" style="visibility:visible; display:block;">
 <table class="fl">
  <td class="ch">
   <A class="A3" title="Id: Kino Polska Muzyka" HREF="http://www.kinopolskamuzyka.pl/" TARGET="_blank">Kino Polska Muzyka</A>
 </tr>
  <td class="ch">
   <i>HBO3 HD</i></td>
 </tr>
  <td class="ch"> Faktura</td>
 </tr>
 '''

soup = bs(html, 'lxml')
items = [item.text.strip() for item in soup.select('td.ch')]
print(items)
