我正在尝试使用ElementTree,它看起来很好,它可以逃脱HTML实体等等.我错过了一些我没听说过的真正精彩的东西吗？
这与我实际做的类似:
import xml.etree.ElementTree as ET
root = ET.Element('html')
head = ET.SubElement(root,'head')
script = ET.SubElement(head,'script')
script.set('type','text/javascript')
script.text = "var a = 'I love á letters'"
body = ET.SubElement(root,'body')
h1 = ET.SubElement(body,'h1')
h1.text = "And I like the fact that 3 > 1"
tree = ET.ElementTree(root)
tree.write('foo.xhtml')
# more foo.xhtml
<html><head><script type="text/javascript">var a = 'I love &aacute;
letters'</script></head><body><h1>And I like the fact that 3 > 1</h1>
</body></html>

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: <spam&egg>."),
... etree.XML("<p>And finally an embedded XHTML fragment.</p>"),
... )
... )
... )
>>> print(etree.tostring(page, pretty_print=True))
<html>
<head>
<title>This is a sample document</title>
</head>
<body>
<h1 class="title">Hello!</h1>
<p>This is a paragraph with <b>bold</b> text in it!</p>
<p>This is another paragraph, with a
<a href="http://www.python.org">link</a>.</p>
<p>Here are some reservered characters: <spam&egg>.</p>
<p>And finally an embedded XHTML fragment.</p>
</body>
</html>

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("""<html>
<head>
<script type="text/javascript">
var a = 'I love &aacute; letters'
</script>
</head>
<body>
<h1>And I like the fact that 3 > 1</h1>
</body>
</html>""")
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
</html>""" % {"message": "I love &aacute; letters"})
