python导入xml文件_python爬虫写入excel

大家好，又见面了，我是你们的朋友全栈君。

最近在使用Testlink时，发现导入的用例是xml格式，且没有合适的工具转成excel格式，xml使用excel打开显示的东西也太多，网上也有相关工具转成csv格式的，结果也不合人意。

那求人不如尔己，自己写一个吧

需要用到的模块有：xml.dom.minidom(python自带)、xlwt

使用版本：

python:2.7.5

xlwt:1.0.0

一、先分析Testlink XML格式：

这是一个有两级testusuit的典型的testlink用例结构，我们只需要取testsuite name,testcase name，preconditions，actions，expectedresults

二、程序如下：

#coding:utf-8

import xml.etree.cElementTree as ET

import xml.dom.minidom as xx

import os,xlwt,datetime

workbook=xlwt.Workbook(encoding=”utf-8″)

#

booksheet=workbook.add_sheet(u’sheet_1′)

booksheet.col(0).width= 5120

booksheet.col(1).width= 5120

booksheet.col(2).width= 5120

booksheet.col(3).width= 5120

booksheet.col(4).width= 5120

booksheet.col(5).width= 5120

dom=xx.parse(r’D:\\Python27\test.xml’)

root = dom.documentElement

row=1

col=1

borders=xlwt.Borders()

borders.left=1

borders.right=1

borders.top=1

borders.bottom=1

style = xlwt.easyxf(‘align: wrap on,vert centre, horiz center’) #自动换行、水平居中、垂直居中

#设置标题的格式，字体方宋、加粗、背景色：菊黄

#测试项的标题

title=xlwt.easyxf(u’font:name 仿宋,height 240 ,colour_index black, bold on, italic off; align: wrap on, vert centre, horiz center;pattern: pattern solid, fore_colour light_orange;’)

item=’测试项’

Subitem=’测试分项’

CaseTitle=’测试用例标题’

Condition=’预置条件’

actions=’操作步骤’

Result=’预期结果’

booksheet.write(0,0,item,title)

booksheet.write(0,1,Subitem,title)

booksheet.write(0,2,CaseTitle,title)

booksheet.write(0,3,Condition,title)

booksheet.write(0,4,actions,title)

booksheet.write(0,5,Result,title)

#冻结首行

booksheet.panes_frozen=True

booksheet.horz_split_pos= 1

#一级目录

for i in root.childNodes:

testsuite=i.getAttribute(‘name’).strip()

#print testsuite

#print testsuite

写测试项

”’

print “row is :”,row

booksheet.write(row,col,testsuite,style)

#二级目录

for dd in i.childNodes:

print ” %s” % dd.getAttribute(‘name’)

testsuite2=dd.getAttribute(‘name’)

if not dd.getElementsByTagName(‘testcase’):

print “Testcase is %s” % testsuite2

row=row+1

booksheet.write(row,2,testsuite2,style) #写测试分项

row=row+1

booksheet.write(row,1,testsuite2,style)

itemlist=dd.getElementsByTagName(‘testcase’)

for subb in itemlist:

#print ” %s” % subb.getAttribute(‘name’)

testcase=subb.getAttribute(‘name’)

row=row+1

booksheet.write(row,2,testcase,style)

ilist=subb.getElementsByTagName(‘preconditions’)

for ii in ilist:

preconditions=ii.firstChild.data.replace(“ “,” “)

col=col+1

booksheet.write(row,3,preconditions,style)

steplist=subb.getElementsByTagName(‘actions’)

#print steplist

for step in steplist:

actions=step.firstChild.data.replace(“ “,” “)

col=col+1

booksheet.write(row,4,actions,style)

#print “测试步骤：”,steplist[0].firstChild.data.replace(“ “,” “)

expectlist=subb.getElementsByTagName(‘expectedresults’)

for expect in expectlist:

result=expect.childNodes[0].nodeValue.replace(“ “,”” )

booksheet.write(row,5,result,style)

row=row+1

workbook.save(‘demo.xls’)

写入excel的效果如下：

我们再来看个实例：

需要下载一个module：xlwt，如下是source code

import xml.dom.minidom

import xlwt

import sys

col = 0

row = 0

def handle_xml_report(xml_report, excel):

problems = xml_report.getElementsByTagName(“problem”)

handle_problems(problems, excel)

def handle_problems(problems, excel):

for problem in problems:

handle_problem(problem, excel)

def handle_problem(problem, excel):

global row

global col

code = problem.getElementsByTagName(“code”)

file = problem.getElementsByTagName(“file”)

line = problem.getElementsByTagName(“line”)

message = problem.getElementsByTagName(“message”)

for node in code:

excel.write(row, col, node.firstChild.data)

col = col + 1

for node in file:

excel.write(row, col, node.firstChild.data)

col = col + 1

for node in line:

excel.write(row, col, node.firstChild.data)

col = col + 1

for node in message:

excel.write(row, col, node.firstChild.data)

col = col + 1

row = row+1

col = 0

if __name__ == ‘__main__’:

if(len(sys.argv) <= 1):

print (“usage: xml2xls src_file [dst_file]”)

exit(0)

#the 1st argument is XML report ; the 2nd is XLS report

if(len(sys.argv) == 2):

xls_report = sys.argv[1][:-3] + ‘xls’

#if there are more than 2 arguments, only the 1st & 2nd make sense

else:

xls_report = sys.argv[2]

xmldoc = xml.dom.minidom.parse(sys.argv[1])

wb = xlwt.Workbook()

ws = wb.add_sheet(‘MOLint’)

ws.write(row, col, ‘Error Code’)

col = col + 1

ws.write(row, col, ‘file’)

col = col + 1

ws.write(row, col, ‘line’)

col = col + 1

ws.write(row, col, ‘Description’)

row = row + 1

col = 0

handle_xml_report(xmldoc, ws)

wb.save(xls_report)
