创建具有BeautifulSoup一个XML文档 [英] Creating an XML document with BeautifulSoup

问题描述

在我看到BeautifulSoup的所有实施例和教程，一个HTML / XML文档被传递并返回汤对象然后可用于修改文件。但是，我怎么能使用BeautifulSoup从头开始创建一个HTML / XML文档？换句话说，我有我想放在一个XML文件中的数据，但XML文件并不存在，我想从头开始构建。我如何做呢？

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

只是创建一个空的 BeautifulSoup（）对象：

Just create an empty BeautifulSoup() object:

soup = BeautifulSoup()

和开始添加元素：

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

有关XML，你可以通过使用 XML 树构建一个XML头开始了：

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

soup = BeautifulSoup(features='xml')

这需要LXML先安装。这台 BeautifulSoup 对象的 .is_xml 标志（也可手动设置）。

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