我使用 lxml 是否是验证 XML 文件语法错误的正确方法？

Question

我正在尝试使用下面的 pom.xml 创建一个 Python 脚本并验证 pom 是否存在任何语法错误，lxml以进一步确认<version>是 aSNAPSHOT并更新<version>以匹配此格式ci_{git hub org}_{branch name}-SNAPSHOT。

project xmlns="http://maven.apache.org/POM/4.0.0" 

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 

 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <modelVersion>4.0.0</modelVersion>

  <groupId>com.wsi.devops</groupId>

  <artifactId>python-test</artifactId>

  <version>1.0-SNAPSHOT</version>

</project>

这是我目前使用我的解决方案的地方，

# For XML validation, importing the etree module from the lxml 

# package, as well as sys for handling input.

from lxml import etree

import sys

#filename as command line arguments

filename_xml = sys.argv[1]

# parse xml

try:

    doc = etree.parse(sys.argv[1])

    print('XML well formed, syntax ok.')

# check for XML syntax errors

except etree.XMLSyntaxError as err:

    print('XML Syntax Error, see error_syntax.log')

    with open('error_syntax.log', 'w') as error_log_file:

        error_log_file.write(str(err.error_log))

    quit()

except:

    print('Unknown error, exiting.')

    quit()

#Update version

from xml.etree import ElementTree as et

tree = et.parse(sys.argv[1])

tree.find('1.0').text = 'ci_{git hub org name}_{branch name}'

tree.write(sys.argv[1])

只是想为我在脚本中犯的任何错误获得一些帮助。
