我想从以下xml(soap api)获取所有id标记值:
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<infasoapns:Body xmlns:eAPI="http://api.ppdi.com/1.1/Site" xmlns:infasoapns="http://schemas.xmlsoap.org/soap/envelope/" xmlns:infawsdlns="http://schemas.xmlsoap.org/wsdl/">
<eAPI:getSiteResponse>
<eAPI:SITE>
<eAPI:Id>CTMSR_1-1036KJ</eAPI:Id>
<eAPI:Sponsor>Ell Inc</eAPI:Sponsor>
<eAPI:CRO>PDP</eAPI:CRO>
<eAPI:Protocol_Number>EL184-308</eAPI:Protocol_Number>
<eAPI:Protocol_Id>CTMSR_1-LCXB0</eAPI:Protocol_Id>
</eAPI:SITE>
<eAPI:SITE>
<eAPI:Id>CTMSR_1-1036SM</eAPI:Id>
<eAPI:Sponsor>Ell Inc</eAPI:Sponsor>
<eAPI:CRO>PDP</eAPI:CRO>
<eAPI:Protocol_Number>EL184-308</eAPI:Protocol_Number>
<eAPI:Protocol_Id>CTMSR_1-LCXB0</eAPI:Protocol_Id>
</eAPI:SITE>
<eAPI:SITE>
<eAPI:Id>CTMSR_1-1036SM</eAPI:Id>
<eAPI:Sponsor>Ell Inc</eAPI:Sponsor>
<eAPI:CRO>PDP</eAPI:CRO>
<eAPI:Protocol_Number>EL184-308</eAPI:Protocol_Number>
<eAPI:Protocol_Id>CTMSR_1-LCXB0</eAPI:Protocol_Id>
</eAPI:SITE>
</eAPI:getSiteResponse>
</infasoapns:Body>
</soapenv:Envelope>
下面是我编写的代码,它在输出中给出了空列表
当我运行tree.findall('.//id')时,它给出了输出:[]
当我运行print(tree.find('id'))时,它给出了输出:none
当我运行tree.find('id').text时,它给出了输出:
---->1 tree.find('id').text中的attributeerror回溯(最近一次调用last)
attributeerror:“nonetype”对象没有属性“text”
代码:
>>> import xml.etree.cElementTree as ElementTree
>>> file_path = 'C:\\Users\\dshukla\\Desktop\\docs\\PPD project\\Response\\WS_SITES_1.1_RES'
>>> tree = ElementTree.parse(file_path)
>>> root = tree.getroot()
>>> print(root)
<Element '{http://schemas.xmlsoap.org/soap/envelope/}Envelope' at 0x00000238F6BFCD10>
>>> tree.findall('.//Id')
[]
>>> tree.find('Id')
>>> print(tree.find('Id'))
None
>>> tree.find('Id').text
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'NoneType' object has no attribute 'text'
>>>
为什么我得到空列表/无类型错误?如何从这个xml文件中获取id标记的值

您需要将名称空间传递给
findall()
. 文件中有四个命名空间。结果是:
