无法在python中使用命名空间解析xml

Question

我试图用lxml和elementree解析python中的xml，但由于名称空间不起作用。

我试过xpath但我没有运气。 另外，如何将xml文档转换为utf-8格式，因为现在我需要添加到xml才能进行解析。

data = """<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<![CDATA[<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Header>
<messageHeader:messageHeader xmlns:messageHeader="http://www.xyx.co.nz/ismm/common/messageHeader/v1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="messageHeader:MessageHeader">
<messageHeader:application>THOM</messageHeader:application>
<messageHeader:transactionId>BVCQWAC</messageHeader:transactionId>
<messageHeader:correlationId>1771518</messageHeader:correlationId>
<messageHeader:timeStamp>2016-11-18T20:41:16</messageHeader:timeStamp>
</messageHeader:messageHeader>
</soapenv:Header>
<soapenv:Body>
<submitSupplierPartner xmlns:customerBill="http://www.xyzaaa.com/ismm/common/customerBill/v1" xsi:type="messaging_supplierPartner:SubmitSupplierPartner">

namespace = "http://schemas.xmlsoap.org/soap/envelope/"
namespace_c = "{" + namespace + "}"
NSMAP = {"soapenv": namespace}
root = lxml.etree.fromstring(data)

# for i, element in enumerate(root.getiterator()):
#     print(element.tag)

#get data from header tag
records = root.xpath('//messageHeader:messageHeader/messageHeader:correlationId', namespaces = {'messageHeader': 'http://www.xyx.co.nz/ismm/common/messageHeader/v1'})
for record in records:
    print(record.text)

#get data from body tag
records = root.xpath('//submitSupplierPartner', namespaces = {"customerBill": "http://www.xyzaaa.com/ismm/common/customerBill/v1"})
for record in records:
    print(record.text)

Answer 1

它对我有用。

数据ID为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)
