使用beautiful soup解析xml

Posted 2020-08-22 life is tough，so are you

比如解析name

authornamelist = soup.find_all(\'contrib\')
    for x in authornamelist:
        print x.surname.text
        print x.surname.next_sibling.next_sibling.text
     

surname.next_sibling实际上是换行符，所有用换行符的next_sibling

直接print x.given-names.text  无法解析given-names这种格式的

.next_sibling 和 .previous_sibling

在文档树中,使用 .next_sibling 和 .previous_sibling 属性来查询兄弟节点:

sibling_soup.b.next_sibling
# <c>text2</c>

sibling_soup.c.previous_sibling
# <b>text1</b>

<b>标签有 .next_sibling 属性,但是没有 .previous_sibling 属性,因为<b>标签在同级节点中是第一个.同理,<c>标签有 .previous_sibling 属性,却没有.next_sibling 属性:

print(sibling_soup.b.previous_sibling)
# None
print(sibling_soup.c.next_sibling)
# None

例子中的字符串“text1”和“text2”不是兄弟节点,因为它们的父节点不同:

sibling_soup.b.string
# u\'text1\'

print(sibling_soup.b.string.next_sibling)
# None
