如何将xml转为python中的字典 import cElementTree as ElementTree class XmlListConfig(list): def __init__(self,aList): for element in aList: if element: # treat like dict if len(element) == 1 or element[0].tag != element[1].tag: self.append(XmlDictConfig(element)) # treat like list elif element[0].tag == element[1].tag: self.append(XmlListConfig(element)) elif element.text: text = element.text.strip() if text: self.append(text) class XmlDictConfig(dict): ‘‘‘ Example usage: >>> tree = ElementTree.parse(‘your_file.xml‘) >>> root = tree.getroot() >>> xmldict = XmlDictConfig(root) Or,if you want to use an XML string: >>> root = ElementTree.XML(xml_string) >>> xmldict = XmlDictConfig(root) And then use xmldict for what it is... a dict. ‘‘‘ def __init__(self,parent_element): if parent_element.items(): self.update(dict(parent_element.items())) for element in parent_element: if element: # treat like dict - we assume that if the first two tags # in a series are different,then they are all different. if len(element) == 1 or element[0].tag != element[1].tag: aDict = XmlDictConfig(element) # treat like list - we assume that if the first two tags # in a series are the same,then the rest are the same. else: # here,we put the list in dictionary; the key is the # tag name the list elements all share in common,and # the value is the list itself aDict = {element[0].tag: XmlListConfig(element)} # if the tag has attributes,add those to the dict if element.items(): aDict.update(dict(element.items())) self.update({element.tag: aDict}) # this assumes that if you‘ve got an attribute in a tag, # you won‘t be having any text. This may or may not be a # good idea -- time will tell. It works for the way we are # currently doing XML configuration files... elif element.items(): self.update({element.tag: dict(element.items())}) # finally,if there are no child tags and no attributes,extract # the text else: self.update({element.tag: element.text}) 用法示例: tree = ElementTree.parse(‘your_file.xml‘) root = tree.getroot() xmldict = XmlDictConfig(root)
//或者,如果你想使用一个XML字符串: root = ElementTree.XML(xml_string) xmldict = XmlDictConfig(root)学习了https://cloud.tencent.com/developer/ask/51220http://code.activestate.com/recipes/410469-xml-as-dictionary/
