通過PyQuery分割抓取的數據

Question

我有以下情況：

<div class="entry">
<p>one</p>
<p>two<br />three<br />four</p>
<p>five<br />six</p>
</div>

我想產生['one','two','three','four','five','six'] 。

到目前為止，我有：

import PyQuery as pq
s = pq(html)
list = [i.text() for i in s('div.entry').find('p').items()]

這只會將其分為<p>標記，而完全忽略<br />標記。 我嘗試了以下方法：

list = [i.text() for i in s(table).find('p').find('br').items()]
list = [i.text() for i in s(table).find('p').find('br').prevAll().items()]
list = [i.split('\n') for i in s(table).find('br').replaceWith('\n')]

這些都不起作用。 此外， PyQuery API將.replaceWith()列為有效函數，但是當我執行test = s(table).find('br').replaceWith('anytext') ，它不會替換為任何東西，我沒有錯誤，只是它們之間帶有<br />標簽的相同項目列表。 .replaceWith()對<br>和<br />區別嗎？

更復雜的例子

<div class="entry">
<p>122 E. Washington St.<br />
734-665-8767</p>

Answer 1

看起來pyquery的行為不符合預期。 使用.contents()解決方法：

>>> import lxml

>>> [e for ptag in s('div.entry').find('p').items()
       for e in ptag.contents()
       if isinstance(e, lxml.etree._ElementStringResult)]
['one', 'two ', 'three', 'four', 'five', 'six']
