如何使用python从一行xml解析文本

Question

I have a single line of xml and would like to parse all text parts into a list of text.

text = '<string name="status">Finishing <xliff:g id="number">%d</xliff:g> percent.</string>'

My desired output:

desired_output = ['Finishing', '%d', 'percent.']

I used regular expression for this simple task.

import re
pattern = re.compile(r'>.+<')
match = re.findall(pattern, text)

match = ['>Finishing <xliff:g id="number">%d</xliff:g> percent.<']

It seems regular expression failed to get my desired output.

Answer 1

I don't know Python well, but I do know that parsing XML with regular expressions is setting yourself up for a world of pain . Try something like this using ElementTree instead, tested in Python 2.7:

import xml.etree.cElementTree as ElementTree
xml_text='<string name="status">Finishing <xliff:g id="number">%d</xliff:g> percent.</string>'
xml=ElementTree.fromstring('<data xmlns:xliff="foo">' + xml_text + '</data>')
print ElementTree.tostring(xml, method='text')

Output:

>>> Finishing %d percent.

Note because there's a namespace in the XML, it needed a wrapper placed around the text. If your actual XML already has the namespace declared, it can be skipped.

update your regex to this

 pattern = re.compile(r'. *?>(.+?)<')

if you are working with xml/html parsing you might consider using Beautifulsoup ,it will save you a great deal of time to write more regex but if you want to learn regex then it will be by trial and error
