python创建xml并完成基本的操作

创建XML文件

首先导入库文件

import xml.dom.minidom as minidom

为了创建如下所示的xml文件我们编写如下代码

<annotation>
	<source>
		<filename>Afilename>
		<origin>Borigin>
	source>
	<research>
		<version>4.0version>
		<provider>Cprovider>
		<author>Dauthor>
		<pluginname>Epluginname>
		<pluginclass>Fpluginclass>
		<time>Gtime>
	research>
	<segmentation>
		<resultfile>Hresultfile>
	segmentation>
annotation>

    def write_xml(num):
        dom = minidom.getDOMImplementation().createDocument(None, 'annotation', None)
        root = dom.documentElement

        element_source = dom.createElement('source')

        element_filename = dom.createElement('filename')
        element_filename.appendChild(dom.createTextNode('{}.tif'.format(num)))
        element_source.appendChild(element_filename)

        element_origin = dom.createElement('origin')
        element_origin.appendChild(dom.createTextNode('GF2/GF3'))
        element_source.appendChild(element_origin)

        root.appendChild(element_source)  ## /source

        ######### research
        element_research = dom.createElement('research')

        element_version = dom.createElement('version')
        element_version.appendChild(dom.createTextNode('4.0'))
        element_research.appendChild(element_version)

        element_provider = dom.createElement('provider')
        element_provider.appendChild(dom.createTextNode('北京理工大学宇航学院系统仿真实验室'))
        element_research.appendChild(element_provider)

        element_author = dom.createElement('author')
        element_author.appendChild(dom.createTextNode('天空之城'))
        element_research.appendChild(element_author)

        element_pluginname = dom.createElement('pluginname')
        element_pluginname.appendChild(dom.createTextNode('高分辨率可见光图像精细化标注'))
        element_research.appendChild(element_pluginname)

        element_pluginclass = dom.createElement('pluginclass')
        element_pluginclass.appendChild(dom.createTextNode('标注'))
        element_research.appendChild(element_pluginclass)

        element_time = dom.createElement('time')
        element_time.appendChild(dom.createTextNode('2020-07-2020-11'))
        element_research.appendChild(element_time)

        element_segmentation = dom.createElement('segmentation')

        element_resultfile = dom.createElement('resultfile')
        element_resultfile.appendChild(dom.createTextNode('{}_gt.png'.format(num)))
        element_segmentation.appendChild(element_resultfile)

        root.appendChild(element_source)  ## /source
        root.appendChild(element_research)
        root.appendChild(element_segmentation)

        # 保存文件
        with open('./result/{}.xml'.format(num), 'w', encoding='utf-8') as f:
            dom.writexml(f, addindent='\t', newl='\n', encoding='utf-8')

1. 创建一个以“”annotation”为根节点的xml文件

 dom = minidom.getDOMImplementation().createDocument(None, 'annotation', None)
 root = dom.documentElement

2. 创建根节点下的子节点

 element_source = dom.createElement('source')
 element_filename = dom.createElement('filename')
 element_filename.appendChild(dom.createTextNode('{}.tif'.format(num)))
 element_source.appendChild(element_filename)
 root.appendChild(element_source)
