我有以下通过xml文件运行并解析的python方法，以及TRIES来编辑字段：
import requests
import xml.etree.ElementTree as ET
import random
def runThrougheTree():
#open xml file
with open("testxml.xml") as xml:
from lxml import etree
#parse
parser = etree.XMLParser(strip_cdata=True, recover=True)
tree = etree.parse("testxml.xml", parser)
root= tree.getroot()
#ATTEMPT to edit field - will not work as of now
for ci in root.iter("CurrentlyInjured"):
ci.text = randomCurrentlyInjured(['sffdgdg', 'sdfsdfdsfsfsfsd','sfdsdfsdfds'])
#Overwrite initial xml file with new fields - will not work as of now
etree.ElementTree(root).write("testxml.xml",pretty_print=True, encoding='utf-8', xml_declaration=True)
#send post (Jboss)
requests.post('http://localhost:9000/something/RuleServiceImpl', data="testxml.xml)
def randomCurrentlyInjured(ran):
random.shuffle(ran)
return ran[0]
#-----------------------------------------------
if __name__ == "__main__":
runThrougheTree()
编辑的XML文件：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:rule="http://somewebsite.com/" xmlns:ws="http://somewebsite.com/" xmlns:bus="http://somewebsite.com/">

问题：
注意：我确保第一个xml标记之前没有字符。
