BeautifulSoup 打印多个标签/属性
首先,这是我第一次尝试使用Python,到目前为止感觉还挺简单的,不过我还是遇到了一些问题。
我想把一个XML文件转换成RSS格式的XML。原始的XML文件看起来是这样的:
<news title="Random Title" date="Date and Time" subtitle="The article txt"></news>
最终应该变成这样:
<item>
<pubDate>Date and Time</pubDate>
<title>Random Title</title>
<content:encoded>The article txt</content:encoded>
</item>
我正在尝试使用Python和BeautifulSoup来实现这个转换,使用的脚本如下:
from BeautifulSoup import BeautifulSoup
import re
doc = [
'<news post_title="Random Title" post_date="Date and Time" post_content="The article txt">''</news></p>'
]
soup = BeautifulSoup(''.join(doc))
print soup.prettify()
posttitle = soup.news['post_title']
postdate = soup.news['post_date']
postcontent = soup.news['post_content']
print "<item>"
print "<pubDate>"
print postdate
print "</pubDate>"
print "<title>"
print posttitle
print "</title>"
print "<content:encoded>"
print postcontent
print "</content:encoded>"
print "</item>"
现在的问题是,它只获取了最上面的一个字符串XML,而没有获取其他的。有没有人能给我一些建议,帮我解决这个问题?
谢谢大家 :)

你的示例文档变量只包含一个 <news>
元素。
但通常情况下,你需要遍历所有的新闻元素。
可以这样做:
for news in soup.findAll('news'):
posttitle = news['post_title']
postdate = news['post_date']
postcontent = news['post_content']
print "<item>"
print "<pubDate>"
print postdate
print "</pubDate>"
print "<title>"
print posttitle
print "</title>"
print "<content:encoded>"
print postcontent
print "</content:encoded>"
print "</item>"

偷取代码并进行修正:
for news in soup.findAll('news'):
posttitle = news['post_title']
postdate = news['post_date']
postcontent = news['post_content']
print "<item>"
print "<pubDate>"
print postdate
print "</pubDate>"
print "<title>"
print posttitle
print "</title>"
print "<content:encoded>"
print postcontent
print "</content:encoded>"
print "</item>"
