有一个test.xml文件，要求读取该文件中products节点的所有子节点的值以及子节点的属性值。
test.xml文件：
<!-- products.xml -->
<root>
<products>
<product uuid='1234'>
<id>10000</id>
<name>苹果</name>
<price>99999</price>
</product>
<product uuid='1235'>
<id>10001</id>
<name>小米</name>
<price>999</price>
</product>
<product uuid='1236'>
<id>10002</id>
<name>华为</name>
<price>9999</price>
</product>
</products>
</root># coding=utf-8
from xml.etree.ElementTree import parse
doc = parse('./products.xml')
print(type(doc))
for item in doc.iterfind('products/product'):
id = item.findtext('id')
name = item.findtext('name')
price = item.findtext('price')
uuid = item.get('uuid')
print('uuid={}, id={}, name={}, price={}'.format(uuid, id, name, price), end='\n----------\n')
