使用Python将CSV转换为XML，以通过API提供

标签： python xml csv

我已经看到了如何将csv（或SQL表）转换为XML的几个答案，但我还没有看到一个包含层次结构且没有过于复杂的问题。我需要将csv文件映射到预先存在的XML格式，以使用Python将其提供给API。我已经可以将有效的XML发送到网站，但我首先要将csv转换为XML。

我的CSV格式为：

OrganizationName,OrdNum,OrdType,OrderTMSStatus,FreightTerms,IsPrePayment,ScheduledEarlyPickup,ScheduledEarlyDelivery,WeightValue,uom,WeightBase,uom2,WeightValue3,uom4,WeightBase5,uom6,VolumeValue,uom7,VolumeBase,uom8,VolumeValue9,uom10,VolumeBase11,uom12,TotalPieceCount,TotalHandlingUnitCount,IsInPlanning,AreTotalsOverridden,CurrencyValue,uom13,CurrencyBase,uom14,IsHot,IsHazmat,BillingStatus,IntegrationStatus,OriginLocNum,OrganizationName15,TradingPartnerNum,TradingPartnerType,LocNum,LocationType,IsActive,IsBillTo,IsRemitTo,IsCorporate,AddrName,Addr1,CityName,StateCode,CountryISO2,PostalCode,CalendarName,CalendarAppointmentName,AllowsHazmat,IsDeliveryAptRequired,IsPickupAptRequired,DestinationLocNum,OrganizationName16,TradingPartnerNum17,TradingPartnerType18,LocNum19,LocationType20,IsActive21,IsBillTo22,IsRemitTo23,IsCorporate24,AddrName25,Addr126,CityName27,StateCode28,CountryISO229,PostalCode30,CalendarName31,CalendarAppointmentName32,AllowsHazmat33,IsDeliveryAptRequired34,IsPickupAptRequired35,OrganizationName36,TradingPartnerNum37,TradingPartnerName,TradingPartnerType38,IsActive39,OrdLineNum,WeightValue40,uom41,WeightBase42,uom43,WeightValue44,uom45,WeightBase46,uom47,VolumeValue48,uom49,VolumeBase50,uom51,VolumeValue52,uom53,VolumeBase54,uom55,PieceCount,HandlingUnitCount,IsHazmat56

这应该是它的样子：

非常感谢帮助。

如果对尝试做类似事情的人有帮助，那就是将有效的XML上传到系统的方式：

import requests
filename = 'somefile.xml'
api_url = 'someurl.com'
headers = {'Content-Type': 'application/xml'}
response = requests.post(api_url, data=open(filename).read(), headers=headers)

没有通用库可以直接将CSV转换为所需的XML。您需要使用python提供的xml函数或使用xml.etree API

之类的函数来构建XML

Here's one sample link

这是一个可以实现它的流程 - ＆gt;

  1. 阅读CSV

  2. 创建名称空间

  3. 创建父节点<Orders>

  4. 阅读CSV。对于每一行，创建一个新节点<Order>并向其添加元素。将此节点作为子节点添加到父<Orders>

  5. 重复步骤4平铺文件结尾

我实际上已经为此找到了一个SQL解决方案......但是对于我的情况来说，它是非常可笑的手动和特定的。我希望这种格式仍能帮助某人解决类似的问题。

如果您从下面的代码中注意到，如果您不包含别名，则XML标记将采用该列的名称。您可以使用“父母/子女”格式。对于层次结构...查看查询的底部以查看多个嵌入式层次结构。

我使用pymssql库在Python内部运行该脚本

#Create a function that reads SQL Query file and returns the result as a string
def queryReturn(query=sql, connection = conn):
    '''
    This function runs a SQL File and returns the result as a strings
    It takes in a T-SQL file as the first argument
    For example:  
    sql=open('sqlFinal.sql', 'r').read().decode('utf-8')
    xml = queryReturn(sql)
    You can also define which database connection to use
    For example: xml = queryReturn(sql,conn)

    '''
    cursor = connection.cursor()
    cursor.execute(query)
    result= "".join([item[0] for item in cursor.fetchall()])
    return result

#Create the header and tail for the XML
header ='''<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns1:OrderData xmlns:ns1="http://schemas.3gtms.com/tms/v1/tns"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Orders>\n '''
tail = '''\n    </Orders>
</ns1:OrderData> '''

#Add uom to the opening tags that need it
xml2=xml2.replace('<WeightValue','<WeightValue uom="Lb"')
xml2=xml2.replace('<WeightBase','<WeightBase uom="Lb"')
xml2=xml2.replace('<VolumeValue','<VolumeValue uom="CuFt"')
xml2=xml2.replace('<VolumeBase','<VolumeBase uom="CuFt"')
xml2=xml2.replace('<CurrencyValue','<CurrencyValue uom="USD"')
xml2=xml2.replace('<CurrencyBase','<CurrencyBase uom="USD"')

然后我将查询的顶部和底部添加到主体：

#create final XML string
final = header+xml2+tail
