python3 xml.dom.pulldom 解析xml

#xml文件

doc  = xml.dom.pulldom.parse("text.xml")--》type 是xml.dom.pulldom.DOMEventStream

#字符串

doc = xml.dom.pulldom.parseString(**)

event is a constant and can be one of:


START_ELEMENT
END_ELEMENT
COMMENT
START_DOCUMENT
END_DOCUMENT
CHARACTERS
PROCESSING_INSTRUCTION
IGNORABLE_WHITESPACE
node is a object of type xml.dom.minidom.Document, xml.dom.minidom.Element or xml.dom.minidom.Text.

查看文档可以知道主要是对doc对象遍历，根据event的值对相应node进行处理其中node的类型可能有( type xml.dom.minidom.Document, xml.dom.minidom.Element or xml.dom.minidom.Text)

示例：

def pullDomParseXML(text=""):
if "" == text:
raise RuntimeError("解析的内容不能为空")
doc = xml.dom.pulldom.parseString(text)
for event,node in doc:
if event == xml.dom.pulldom.START_ELEMENT:
print("开始解析:",node.tagName,"标签")
elif event == xml.dom.pulldom.CHARACTERS and node.data !="\n" and node.data.strip() !="":
print("标签内容:",node.data)
elif event == xml.dom.pulldom.END_ELEMENT:
print("标签:",node.tagName,"解析结束")
