请问，如何获取以下数据：（？）

inv：invoiceSummary - typ：priceHighSum

inv：partnerIdentity - typ：name，typ：ico

inv：myIdentity - typ：company

inv：清算 - 典型：日期

我尝试了这个但却无法正常工作：

import xml.etree.ElementTree as ET
tree = ET.parse('temp_xml2.xml')
root = tree.getroot()


for listInvoice in root.findall('listInvoice'):
    invoiceHeader = listInvoice.find('invoiceHeader').text
    print invoiceHeader

尝试使用jsoup。在相关示例中是parse XML。

答案 1 :(得分：0)

这有效：

for listInvoice in root.findall('.//{http://www.stormware.cz/schema/version_2/invoice.xsd}invoiceHeader'):
    invoiceHeader = listInvoice.find('.//{http://www.stormware.cz/schema/version_2/invoice.xsd}id').text
    print invoiceHeader
