csv文件

 

code

from xml.etree.ElementTree import Element,ElementTree,tostring
import json,csv

def csvtoxml(fname):
    with open(fname,\'r\') as f:
        reader=csv.reader(f)
        header=next(reader)
        root=Element(\'Daaa\')
        print(\'root\',len(root))
        for row in reader:
            erow=Element(\'Row\')
            root.append(erow)
            for tag,text in zip(header,row):
                e=Element(tag)
                e.text=text
                erow.append(e)
    beatau(root)
    return ElementTree(root)



def beatau(e,level=0):
    if len(e)>0:
        e.text=\'\\n\'+\'\\t\'*(level+1)
        for child in e:
           beatau(child,level+1)
        child.tail=child.tail[:-1]
    e.tail=\'\\n\' + \'\\t\'*level
    
et=csvtoxml(r\'C:\\Temp\\ff.csv\')
et.write(r\'C:\\Temp\\fff.xml\')
