xml基础（二）

有了上面的xml基础了，可以用Python生成相应的vxt文件了。

直接上代码：

import xml.etree.ElementTree as ET
#生成canmsg元素
def canmsg_element(id_input,bus_input):
    canmsg_ele=ET.Element("canmsg",{"id":id_input,"bus":bus_input})
    return canmsg_ele

#生成signalref元素
def signalref_element(name_input,refname_input):
    signalref_ele=ET.Element("signalref",{"name":name_input,"refname":refname_input})
    return signalref_ele

#生成request元素
def request_element(id_input,bus_input):
    request_ele=ET.Element("request")
    canmsg_ele=canmsg_element(id_input,bus_input)
    request_ele.append(canmsg_ele)
    return request_ele

#生成response元素
def response_element(id_input,bus_input,signalref_name_input,refname_input):
    response_ele=ET.Element("response")
    canmsg_ele=canmsg_element(id_input,bus_input)
    signalref_ele=signalref_element(signalref_name_input,refname_input)
    canmsg_ele.append(signalref_ele)
    response_ele.append(canmsg_ele)
    return response_ele

#生成requestresponsecheck元素
def requestresponsecheck(timeout,mintime,id_request,bus_request,id_response,
                         bus_response,signalref_name,refname):
    requestresponsecheck_ele=ET.Element("requestresponsecheck",{"timeout":timeout,"mintime":mintime})
    request_ele=request_element(id_request,bus_request)
    response_ele=response_element(id_response,bus_response,signalref_name,refname)
    requestresponsecheck_ele.append(request_ele)
    requestresponsecheck_ele.append(response_ele)
    return requestresponsecheck_ele

#生成cansignal元素
def cansignal(name,msg,bus,text_input):
    cansignal_ele=ET.Element('cansignal',{'name':name,"msg":msg,'bus':bus})
    cansignal_ele.text=text_input
    return cansignal_ele

#生成initialize元素
def initialize(title_init,wait,name,msg,bus,text):
    initialize_ele=ET.Element('initialize',{'title':title_init,'wait':wait})
    cansignal_ele=cansignal(name,msg,bus,text)
    initialize_ele.append(cansignal_ele)
    return initialize_ele

#生成testcase元素
def testcase(title,ident,title_init,wait,name,msg,bus,text_from,text_to):
    testcase_ele=ET.Element('testcase',{'title':title,'ident':ident})
    initialize_from=initialize(title_init,wait,name,msg,bus,text_from)
    initialize_to=initialize(title_init,wait,name,msg,bus,text_to)
    testcase_ele.append(initialize_from)
    testcase_ele.append(initialize_to)
    return testcase_ele
