如何更改标签名BeautifulSoup？ [英] How to change tag name with BeautifulSoup?
问题描述
我使用Python + BeautifulSoup解析HTML文档。
I am using python + BeautifulSoup to parse an HTML document.
现在我需要替换所有的＆LT; H2类=SomeClass的＆GT; 元素在HTML文档中，用＆LT; H1类= SomeClass的＆GT; 。
Now I need to replace all <h2 class="someclass"> elements in an HTML document, with <h1 class="someclass">.
如何更改标签名称，没有文件改变什么吗？
How can I change the tag name, without changing anything else in the document?
推荐答案
我不知道你是如何访问标记但对我来说了以下工作：
I don't know how you're accessing tag but the following works for me:
import BeautifulSoup
if __name__ == "__main__":
data = """
<html>
<h2 class='someclass'>some title</h2>
<ul>
<li>Lorem ipsum dolor sit amet, consectetuer adipiscing elit.</li>
<li>Aliquam tincidunt mauris eu risus.</li>
<li>Vestibulum auctor dapibus neque.</li>
</ul>
</html>
"""
soup = BeautifulSoup.BeautifulSoup(data)
h2 = soup.find('h2')
h2.name = 'h1'
print soup
的打印输出汤命令是：
<html>
<h1 class='someclass'>some title</h1>
<ul>
<li>Lorem ipsum dolor sit amet, consectetuer adipiscing elit.</li>
<li>Aliquam tincidunt mauris eu risus.</li>
<li>Vestibulum auctor dapibus neque.</li>
</ul>
</html>
正如你所看到的， H2 成为 H1 。并没有别的文件中的变化。我使用Python 2.6和3.2.0 BeautifulSoup
As you can see, h2 became h1. And nothing else in the document changed. I am using Python 2.6 and BeautifulSoup 3.2.0.
如果您有多个 H2 更多你想改变它们，你可以简单的做：
If you have more than one h2 and you want to change them all, you could simple do:
soup = BeautifulSoup.BeautifulSoup(your_data)
while True:
h2 = soup.find('h2')
if not h2:
break
h2.name = 'h1'
