我制作了一个使用 argparse 将 csv 文件转换为 xml 文件的程序。首先它将读取 csv 文件作为输入文件,然后将其转换为 xml 文件。这是我的代码:
import sys, argparse
import csv
import indent
from xml.etree.ElementTree import ElementTree, Element, SubElement, Comment, tostring
parser=argparse.ArgumentParser(description='Convert wordlist text files to various formats.', prog='Text Converter')
parser.add_argument('-v','--verbose',action='store_true',dest='verbose',help='Increases messages being printed to stdout')
parser.add_argument('-c','--csv',action='store_true',dest='readcsv',help='Reads CSV file and converts to XML file with same name')
parser.add_argument('-x','--xml',action='store_true',dest='toxml',help='Convert CSV to XML with different name')
parser.add_argument('-i','--inputfile',type=argparse.FileType('r'),dest='inputfile',help='Name of file to be imported',required=True)
parser.add_argument('-o','--outputfile',type=argparse.FileType('w'),dest='outputfile',help='Output file name')
args = parser.parse_args()
def main(argv):
reader = read_csv(args.inputfile)
if args.verbose:
print ('Verbose Selected')
if args.toxml:
if args.verbose:
print ('Convert to XML Selected')
generate_xml(reader, args.outputfile)
if args.readcsv:
if args.verbose:
print ('Reading CSV file')
if not (args.toxml or args.readcsv):
parser.error('No action requested')
return 1
def read_csv(inputfile):
return list(csv.reader(inputfile))
def generate_xml(reader,outfile):
root = Element('Solution')
root.set('version','1.0')
tree = ElementTree(root)
head = SubElement(root, 'DrillHoles')
head.set('total_holes', '238')
description = SubElement(head,'description')
current_group = None
i = 0
for row in reader:
if i > 0:
x1,y1,z1,x2,y2,z2,cost = row
if current_group is None or i != current_group.text:
current_group = SubElement(description, 'hole',{'hole_id':"%s"%i})
collar = SubElement (current_group, 'collar',{'':', '.join((x1,y1,z1))}),
toe = SubElement (current_group, 'toe',{'':', '.join((x2,y2,z2))})
cost = SubElement(current_group, 'cost',{'':cost})
i+=1
indent.indent(root)
tree.write(outfile)
if (__name__ == "__main__"):
sys.exit(main(sys.argv))
然后在我写的命令提示符下, Argparse.py -i 1250_12.csv -o output.xml -x 其中 argparse 是程序名称,1250_12.csv 是 csv 文件名,而 output.xml 是我想要的输出名称-x 是将 csv 转换为 xml 的操作。该程序在 10 分钟前运行,现在出现错误消息:
x1,y1,z1,x2,y2,z2,cost = row
Value error: need more than 1 value to unpack
