无法用python中的命名空间解析xml

问题描述：

我想用lxml和elementree解析python中的xml，但是由于命名空间，它不起作用。我试过xpath但我没有运气。此外，如何将xml文档转换为utf-8格式，因为现在我需要将其添加到xml中进行解析。无法用python中的命名空间解析xml

它为我工作。

数据ID中的XML

root = lxml.etree.fromstring(data) 

#orderId/uniqueCreatorId 
records = root.xpath('//submitSupplierPartner/logisticsOrder/orderId') 
for record in records: 
    orderID=record.text 
    print(orderID) 

#sim and devices ID 

hardwareID = [] 

records = root.xpath('//submitSupplierPartner/logisticsOrder/resourceOrderItem/resourceSpecification/ID') 
for record in records: 
    hardwareID.append(record.text) 
print(hardwareID) 

#get the no of items for shipping 
noOfItems = len(hardwareID) 
print("Total items for shipping are :") 
print(noOfItems) 

#sim and devices skuNumber 
hardwaresku = [] 
records = root.xpath('//submitSupplierPartner/logisticsOrder/resourceOrderItem/resourceSpecification/skuNumber') 
for record in records: 
    hardwaresku.append(record.text) 
print(hardwaresku) 

#sim and devices itemId 
hardwareitemID = [] 
records = root.xpath('//submitSupplierPartner/logisticsOrder/resourceOrderItem/itemId') 
for record in records: 
    hardwareitemID.append(record.text) 
print(hardwareitemID) 

#correlation ID/Rom 
records = root.xpath('//messageHeader:messageHeader/messageHeader:correlationId/text()',namespaces={"messageHeader": "http://www.xyz.co.nz/ismm/common/messageHeader/v1"}) 
for record in records: 
    correlationID = record 
    print(record)
