我很惊讶XML基本对象(twisted.words.xish.domish.Element)无法完全从XML字符串创建。最相似的方式是:
msg = "<iq to='juick@juick.com' id='id123' type='get'> \
<query xmlns='http://juick.com/query#messages' mid='123456'/> \
</iq>"
iq = domish.Element(('',''))
iq.addRawXml(msg)
但它会产生:
iq.toXml()
u"<><iq to='juick@juick.com' id='id123' type='get'> <query xmlns='http://juick.com/query#messages' mid='123456'/> </iq></>"
除了编写自己的IElement实现之外,有没有办法使用原始XML?
答案 0 :(得分:1)
这就是我用于片段的内容,它改编自网络上的某些内容。
from twisted.words.xish import domish
class ElementParser(object):
"callable class to parse XML string into Element"
def __call__(self, s):
self.result = None
def onStart(el):
self.result = el
def onEnd():
pass
def onElement(el):
self.result.addChild(el)
parser = domish.elementStream()
parser.DocumentStartEvent = onStart
parser.ElementEvent = onElement
parser.DocumentEndEvent = onEnd
tmp = domish.Element(("", "s"))
tmp.addRawXml(s)
parser.parse(tmp.toXml())
return self.result.firstChildElement()
