Python：提取除某些标签外的 XML 文本

Question

I have this example XML file:

<page>
  <title>Chapter 1</title>
  <content>Welcome to Chapter 1</content>
  <author>John Smith</author>
</page>
<page>
 <title>Chapter 2</title>
 <content>Welcome to Chapter 2</content>
 <author>John Doe</author>
</page>

This XML may have multiple levels (ie more than 2) and may have other tags. I wish to extract all texts except those under the tag "content", so that I get a list of strings as follows:

['Chapter 1', 'John Smith', 'Chapter 2', 'John Doe']

I'm implementing this task using ElementTree. Is there any elegant, clean solution?

Answer 1

import bs4

xml = '''<page>
  <title>Chapter 1</title>
  <content>Welcome to Chapter 1</content>
  <author>John Smith</author>
</page>
<page>
 <title>Chapter 2</title>
 <content>Welcome to Chapter 2</content>
 <author>John Doe</author>
</page>'''

soup = bs4.BeautifulSoup(xml, 'lxml')
[(page.title.text, page.author.text)for page in soup('page')]

out:

[('Chapter 1', 'John Smith'), ('Chapter 2', 'John Doe')]

Use BeautifulSoup as XML parser, you can reference Document
