使用 Python 操作 xml

我正在使用Python 3.9。我有一个像这样的嵌套 xml 文档字符串负载_xml =“”“ ... ... ... 我使用的是Python 3.9。我有一个像这样的嵌套 xml 文档字符串 payload_xml = """ <AllData> <MyPayload> ... ... ... </MyPayload> </AllData> """ 现在我想创建另一个父 xml 文档字符串，并将此有效负载提取到新创建的 xml 文档中，如下所示新 XML <Full_Message prop1="" prop2=""> <Header> <headerValue1> </headerValue1> <headerValue2> </headerValue2> <headerValue3> </headerValue3> <NestedValues> <someval1> </someval> </NestedValues> </Header> <Body>  </Body> </Full_Message> 这是我目前所在的位置 from lxml import etree FullMessage_root = etree.Element("Full_Message") AllData_root = etree.fromstring(payload_xml) payload_only = AllData_root[0] FullMessage_root.append(payload_only) FullMessage_root.insert(0, etree.Element("Header")) FullMessage_root.insert(1, etree.Element("Body")) FullMessage_root.attrib['prop1']='hello world' 这会导致： <Full_Message prop1="hello world"> <Header/> <Body/> <MyPayload> </MyPayload> </Full_Message> 如何将 <MyPayload> 嵌套在 <Body> 标签中并在 <Header> 中创建多个嵌套值？以下是实现您目标的一种方法。我们从上到下逐层创建新的 XML，并使用 append 将子元素附加到父元素。 import xml.etree.ElementTree as ET def create_elements(parent_ele, child_tags, child_vals): for tag, val in zip(child_tags, child_vals): ele = ET.Element(tag) if val: ele.text = val parent_ele.append(ele) payload_xml = ''' <AllData> <MyPayload> Foo </MyPayload> </AllData> ''' # Create root root = ET.Element('Full_Message') root.set('prop1', 'some prop') root.set('prop2', 'other prop') # Add elements to root create_elements( root, ['Header', 'Body'], [None] * 2, # no text value attached to header and body ) # Add elements to header create_elements( root.find('Header'), ['headerValue1', 'headerValue2', 'headerValue3', 'NestedValues'], ['val1', 'val2', 'val3', None], # note that no text value attached to NestedValues ) # Add elements to NestedValues create_elements( root.find('Header').find('NestedValues'), ['someval1', 'someval2', 'someval3'], ['nested val1', 'nested val2', 'nested val3'], ) # Insert payload AllData_root = ET.ElementTree(ET.fromstring(payload_xml)).getroot() root.find('Body').append(AllData_root) # print the new XML ET.indent(root) print(ET.tostring(root, encoding='unicode')) 输出将是 <Full_Message prop1="some prop" prop2="other prop"> <Header> <headerValue1>val1</headerValue1> <headerValue2>val2</headerValue2> <headerValue3>val3</headerValue3> <NestedValues> <someval1>nested val1</someval1> <someval2>nested val2</someval2> <someval3>nested val3</someval3> </NestedValues> </Header> <Body> <AllData> <MyPayload> Foo </MyPayload> </AllData> </Body> </Full_Message>

Clinical manifestations range from asymptomatic to severe, depending on the degree of tricuspid valve displacement and severity of regurgitation, the effective right ventricular volume, and the associated malformations (i.e., pulmonary valve stenosis, atresia, atrial septal defect, etc.). Arrhythmias are common and protracted due to the likelihood of having accessory pathways, in addition to having right atrial dilatation.
