使用 BeautifulSoup 创建 XML 文档 [英] Creating an XML document with BeautifulSoup

问题描述

在我看过的所有关于 BeautifulSoup 的示例和教程中，传递了一个 HTML/XML 文档并返回一个汤对象，然后可以使用它来修改文档.但是，如何使用 BeautifulSoup 从头开始​​创建 HTML/XML 文档?换句话说，我想将数据放入 XML 文件中，但 XML 文件尚不存在，我想从头开始构建它.我该怎么办?

In all the examples and tutorials I have seen of BeautifulSoup, an HTML/XML document is passed and a soup object is returned which can then be used to modify the document. However, how can I use BeautifulSoup to create a HTML/XML document from scratch? In other words, I have data that I would like to put in an XML file, but the XML file does not exist yet and I would like to build it from scratch. How can I go about it?

推荐答案

只需创建一个空的 BeautifulSoup() 对象:

Just create an empty BeautifulSoup() object:

soup = BeautifulSoup()

并开始添加元素:

soup.append(soup.new_tag("a", href="http://www.example.com"))

对于 XML，您可以使用 xml 树构建器从 XML 标头开始:

For XML you could start out with a XML header by using the xml tree builder:

soup = BeautifulSoup(features='xml')

这需要先安装lxml.这会在 BeautifulSoup 对象上设置 .is_xml 标志(也可以手动设置).

This requires lxml to be installed first. This sets the .is_xml flag on the BeautifulSoup object (which can also be set manually).
