我正在尝试解析从“POST”请求中获得的XML内容。 问题是当我检查'roots'*或项目的'tags'时,它们在应该检查的时候没有值。你知道吗
XML内容的一部分如下所示:

为了处理文件,我保存了它并再次加载它以处理内容:
with open('C://Users/xyz/Documents/topnewsfeed.xml', 'wb') as f:
f.write(response.content)
f.close()
tree = ET.parse('C://Users/xyz/Documents/topnewsfeed.xml')
问题是,当我尝试检查与价值相关的项目时(包含值的标记:
章节内容:
<tblIndicePrincipal_Mes diffgr:id="tblIndicePrincipal_Mes12" msdata:rowOrder="11">
<IndicePrincipalID>4140</IndicePrincipalID>
<DataIndice>2016-12-01T00:00:00-02:00</DataIndice>
<ValorIndice>203.649516</ValorIndice>
<Base>0</Base>
提取/检查价值的代码:
root = tree.getroot()
for item in root.findall('./NewDataSet/tblIndicePrincipal_Mes/ValorIndice'):
print(item.tag())
因此,我得到以下结果(没有显示任何内容)
> for item in root.findall('./NewDataSet/tblIndicePrincipal_Mes/ValorIndice'):
print(item.tag())
>
