python - 如何使用正则表达式或工具包将句子解析为标记

Question

如何使用正则表达式或 beautifulsoup、lxml 等工具包解析这样的句子:

input = """Yesterday<person>Peter Smith</person>drove to<location>New York</location>"""

进入此:

Yesterday
<person>Peter Smith</person>
drove
to
<location>New York</location>

我无法使用re.findall("<person>(.*?)</person>", input)因为标签不同。

Answer 1

看看使用 BeautifulSoup 是多么容易:

from bs4 import BeautifulSoup

data = """Yesterday<person>Peter Smith</person>drove to<location>New York</location>"""

soup = BeautifulSoup(data, 'html.parser')
for item in soup:
    print item

打印:

Yesterday
<person>Peter Smith</person>
drove to
<location>New York</location>

UPD(将非标记项拆分为空格并在新行上打印每个部分):

soup = BeautifulSoup(data, 'html.parser')
for item in soup:
    if not isinstance(item, Tag):
        for part in item.split():
            print part
    else:
        print item

打印:

Yesterday
<person>Peter Smith</person>
drove
to
<location>New York</location>

希望有帮助。
