python中使用xml.dom.minidom模块读取解析xml文件

python中可以使用xml.dom.minidom模块读取解析xml文件

xml.dom.minidom模块应该是内置模块不用下载安装
对于一个xml文件来说比如这个xml文件的内容为如下

<excel version="1.0" author="huangzhihui">
    <table id="1">
        <colum id="1.1" name="Mike1" width="1" height="1" />
        <colum id="1.2" name="John1" width="2" height="2" />
        <colum id="1.3" name="Lucy1" width="3" height="3" />
    table>
    <table id="2">
        <colum id="2.1" name="Mike1" width="1" height="1" />
        <colum id="2.2" name="John1" width="2" height="2" />
        <colum id="2.3" name="Lucy1" width="3" height="3" />
    table>
excel>

代码如下

from xml.dom import minidom

doc = minidom.parse(r'C:\Users\xxxxxxx\Desktop\test.xml')  #解析xml文件(句柄或文件路径)
#doc = minidom.parseString()  #解析xml字符串
root_node = doc.documentElement  #获得根节点对象
xml_excel_obj_list = root_node.getElementsByTagName('excel')
print(xml_excel_obj_list)

xml_table_obj_list = root_node.getElementsByTagName('table')
print(xml_table_obj_list)

for table in xml_table_obj_list:
    print("==========================")
    lines_obj_list = table.getElementsByTagName('colum')
    for line_obj in lines_obj_list:
        print(line_obj.getAttribute("name"), line_obj.getAttribute("width"), line_obj.getAttribute("height"))
    print("==========================")
