【python小随笔】python 解析xml数据的新手大坑>>抓取多重标签，遍历各标签的数据

xml文档:

<GetMatchingProductResult ASIN="B071LF9R6G" status="Success">...</GetMatchingProductResult>

<GetMatchingProductResult ASIN="B0714BP3H4" status="Success">...</GetMatchingProductResult>

<GetMatchingProductResult ASIN="B0756FL8R7" status="Success">...</GetMatchingProductResult>

# 使用minidom解析器打开XML文档

DOMTree = xml.dom.minidom.parse("./test.xml")

collection = DOMTree.documentElement

# collection是针对整个文件的文档,GetMatchingProductResults 获取的是三个名字相同的标签,不同标签的数据对象

GetMatchingProductResults = collection.getElementsByTagName('GetMatchingProductResult')

# GetMatching 是针对每个标签对象GetMatching作为xml对象进行对应取值

for GetMatching in GetMatchingProductResults:

    asin = GetMatching.getElementsByTagName('ASIN')[0].childNodes[0].data

    print(asin)
