Library for XML+XPath in Python?

Question

Python

I have an XML file with the following structure:

<?xml version="1.0" encoding="UTF-8"?>
<DeviceData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="DIGSIXML1-4.xsd">
     <Settings>
          <FunctionGroup Name="Данные энергосистемы 1">
               <SettingPage Name="Парам ТТ/ТН">
                    <Parameter DAdr="0205" Name="Первичный номинальный ток ТТ" Type="Dec">
                         <Value>1000</Value>
                         <Comment Dimension="А" MinValue="10" MaxValue="5000" DefaultValue="1000"/>
                    </Parameter>
                    <Parameter DAdr="0206" Name="Вторичный номинальный ток ТТ" Type="Txt">
                         <Value>12922</Value>
                         <Comment Number="12921" Name="1А"/>
                         <Comment Number="12922" Name="5А"/>
                         <Comment DefaultValue="12921"/>
                    </Parameter>
                    <Parameter DAdr="0210" Name="U4 трансформатор напряжения подкл. как" Type="Txt">
                         <Value>12508</Value>
                         <Comment Number="12508" Name="Не подключен"/>
                         <Comment Number="12790" Name="Uдельта трансформатора напряжения"/>
                         <Comment DefaultValue="12508"/>
                    </Parameter>
               </SettingPage>
          </FunctionGroup>
     </Settings>
</DeviceData>

You need a library for working with XML that supports full-fledged XPath queries, specifically you need this:

//Parameter[@DAdr="0206"]/Comment[@Number=//Parameter[@DAdr="0206"]/Value/text()]/@Name

those. First, we look for the Parameter element with the @DAdr="0206" attribute, then among its Comment subelements we look for one whose @Number attribute matches the text of the Value subelement of the same Parameter element, and at the very end we take the value of the @Name attribute of the found element.
Those. nested queries. For example, this is supported in the XML Tools plugin for Notepad++. Neither ElementTree nor lxml can do this. These XPath queries come from the config, so it will not be possible to search for elements sequentially in the code.
Please advise a library for Python, I tried to find something on the github, but most of it can’t even be installed on the go.
