另一种方法是使用lxml中的E Factory构建器(也可以在Elementtree中使用)

>>> from lxml import etree

>>> from lxml.builder import E

>>> def CLASS(*args): # class is a reserved word in Python
...     return {"class":' '.join(args)}

>>> html = page = (
...   E.html(       # create an Element called "html"
...     E.head(
...       E.title("This is a sample document")
...     ),
...     E.body(
...       E.h1("Hello!", CLASS("title")),
...       E.p("This is a paragraph with ", E.b("bold"), " text in it!"),
...       E.p("This is another paragraph, with a", "\n      ",
...         E.a("link", href="http://www.python.org"), "."),
...       E.p("Here are some reserved characters: ."),
...       etree.XML("
And finally an embedded XHTML fragment.
"),
...     )
...   )
... )

>>> print(etree.tostring(page, pretty_print=True))

  
    
  
  
    
Hello!
    
This is a paragraph with bold text in it!
    
This is another paragraph, with a
      link.
    
Here are some reservered characters: <spam&egg>.
    
And finally an embedded XHTML fragment.
  

总有SimpleXMLWriter,它是ElementTree工具包的一部分.界面很简单.

这是一个例子:

from elementtree.SimpleXMLWriter import XMLWriter
import sys

w = XMLWriter(sys.stdout)
html = w.start("html")

w.start("head")
w.element("title", "my document")
w.element("meta", name="generator", value="my application 1.0")
w.end()

w.start("body")
w.element("h1", "this is a heading")
w.element("p", "this is a paragraph")

w.start("p")
w.data("this is ")
w.element("b", "bold")
w.data(" and ")
w.element("i", "italic")
w.data(".")
w.end("p")

w.close(html)

我假设你实际上是在创建一个XML DOM树,因为你想要验证进入这个文件的是有效的XML,因为否则你只需要在文件中写一个静态字符串.如果确认你的输出确实是你的目标,那么我建议

from xml.dom.minidom import parseString

doc = parseString("""
    
        
    
    
        
And I like the fact that 3 > 1
    
    """)

with open("foo.xhtml", "w") as f:
    f.write( doc.toxml() )

这使您可以只编写要输出的XML,验证它是否正确(因为如果它无效,parseString将引发异常)并让您的代码看起来更好.

据推测,您不仅每次都编写相同的静态XML,而且还需要进行一些替换.在这种情况下,我会有类似的行

var a = '%(message)s'

然后使用%运算符进行替换,例如

""" % {"message": "I love á letters"})
