根据属性去找这个元素，然后获取它的另一个属性值
def GetElement(TypeName,TypeValue): self.GetActivitXml("MarketTest") tree = ET.ElementTree(file=PATH("MarketTest.xml")) Elements = tree.iter(tag="node") for Element in Elements: if Element.attrib[TypeName] == TypeValue: bounds = Element.attrib["bounds"] 根据路径查找到元素
def GetXpathElement(xpath): self.GetActivitXml("MarketTest") tree = ET.ElementTree(file=PATH("MarketTest.xml")) root = tree.getroot() for index in xpath: root = root[index] XPath 语法
