python-3.x - 从完整的 xpath 生成 xml

Question

我在 xpath 中得到了如下所示的 xpath

在 xpath 中，字符 '[r]'、'[k]'、'[i]' 表示 iter，我可以找到 Iter 的起始编号。和 UUIDofk-thdrug 也是变量，我也有。

我尝试仅在 xml 路径中提取标签值，如下所示 /MCCI_IN200100UV01/PORR_IN049016UV/controlActProcess/subject/investigationEvent/component/ .....

有了这个我想生成包含属性的xml代码

/hl7:MCCI_IN200100UV01[@ITSVersion='XML_1.0'][@xsi:schemaLocation='urn:hl7-org:v3 MCCI_IN200100UV01.xsd']/hl7:PORR_IN049016UV[r]/hl7:controlActProcess[@classCode='CACT'][@moodCode='EVN']/hl7:subject[@typeCode='SUBJ'][1]/hl7:investigationEvent[@classCode='INVSTG']
[@moodCode='EVN']/hl7:component[@typeCode='COMP'][hl7:adverseEventAssessment][1]/hl7:adverseEventAssessment[@classCode='INVSTG'][@moodCode='EVN']/hl7:component[@typeCode='COMP'][hl7:causalityAssessment/hl7:code[@code='39'][@codeSystem='2.16.840.1.113883.3.989.2.1.1.19']][r]/hl7:causalityAssessment[@classCode='OBS'][@moodCode='EVN'][hl7:subject1[@typeCode='SUBJ']/hl7:adverseEffectReference[@classCode='OBS'][@moodCode='EVN']/hl7:id[@root='UUIDofi-threaction']][hl7:subject2[@typeCode='SUBJ']/hl7:productUseReference[@classCode='SBADM'][@moodCode='EVN']/hl7:id[@root='UUIDofk-thdrug']]/hl7:value[@xsi:type='ST']/text()

手写示例如下。我想将我的值放入正确的路径中，在上面的示例 xpath 中，该值将像下面的示例 xml 一样插入。

<<?xml version="1.0" encoding="UTF-8"?>
<MCCI_IN200100UV01 ITSVersion="XML_1.0" xsi:schemaLocation="urn:hl7-org:v3 MCCI_IN200100UV01.xsd" xmlns="urn:hl7-org:v3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

在 python 中使用上面的 xpath 生成 xml 的最佳方法是什么？
