如何用python将多个结构相同的xml文件合并成一个xml文件

[Sleepy丶head]

一下是我生成xml的办法，有什么别的办法可以将这么多字典存进一个xml文件吗？

for j in range(0,len(vul_type)):
    vulnerabilities = {'texttttt':{"Type":vul_type[j].text,
                       "CWE":CWE[j],
                       "CVSS":CVSS[j],
                       "Desciption":Desciption[j],
                       "Impact":Impact[j],
                       "Recommendation":Recommendation[j],
                       }}

    # with open('out.xml', 'w') as f:
    #     f.write(xmltodict.unparse(vulnerabilities))
    filename = str(j)+'.xml'
    f = open(filename, 'w')
    f.write(xmltodict.unparse(vulnerabilities))
    f.close()
