使用BeautifulSoup从XML文件读取CDATA [英] Reading CDATA from XML file with BeautifulSoup

问题描述

我在XML文件中保存了以下推文:

I have tweets saved in an XML file as:

<tweet>
  <tweetid>142389495503925248</tweetid>
  <user>ccifuentes</user>
  <content><![CDATA[Salgo de #VeoTV , que día más largoooooo...]]></content>
  <date>2011-12-02T00:47:55</date>
  <lang>es</lang>
  <sentiments>
   <polarity><value>NONE</value><type>AGREEMENT</type></polarity>
  </sentiments>
  <topics>
   <topic>otros</topic>
  </topics>
 </tweet>

要解析这些内容，我通过创建一个BeautifulSoup实例

To parse these, I created a BeautifulSoup instance via

soup = BeautifulSoup(xml, "lxml")

其中xml是原始XML文件.要访问一条推文，我这样做:

where xml is the raw XML file. To access a single tweet I did this:

tweets = soup.find_all('tweet')
for tw in tweets:
    print(tw)
    break

这将导致

<tweet>
<tweetid>142389495503925248</tweetid>
<user>ccifuentes</user>
<content></content>
<date>2011-12-02T00:47:55</date>
<lang>es</lang>
<sentiments>
<polarity><value>NONE</value><type>AGREEMENT</type></polarity>
</sentiments>
<topics>
<topic>otros</topic>
</topics>
</tweet>

请注意，当我打印第一条Tweet时，省略了CDATA部分.对我来说很重要，我该怎么办?

Note that the CDATA part was omitted when I printed the first tweet. It is important for me to get it, how can I do this?

推荐答案

soup = bs4.BeautifulSoup(xml, 'xml')

将解析器更改为 xml

退出:

<content>Salgo de #VeoTV , que día más largoooooo...</content>

或 html.parser :

soup = bs4.BeautifulSoup(xml, 'html.parser')

退出:

<content><![CDATA[Salgo de #VeoTV , que día más largoooooo...]]></content>
