我正在从以下网站解析 html:http ://www.asusparts.eu/partfinder/Asus/All In One/E 系列 我只是想知道是否有任何方法可以探索 python 中的解析属性?例如.. 下面的代码输出以下内容:
datas = s.find(id='accordion')
a = datas.findAll('a')
for data in a:
if(data.has_attr('onclick')):
model_info.append(data['onclick'])
print data
[输出]
<a href="#Bracket" onclick="getProductsBasedOnCategoryID('Asus','Bracket','ET10B','7138', this, 'E Series')">Bracket</a>
这些是我想检索的值:
nCategoryID = Bracket
nModelID = ET10B
family = E Series
由于页面是从 AJAX 呈现的,因此他们使用脚本源,从而从脚本文件中生成以下 url:
url = 'http://json.zandparts.com/api/category/GetCategories/' + country + '/' + currency + '/' + nModelID + '/' + family + '/' + nCategoryID + '/' + brandName + '/' + null
我怎样才能只检索上面列出的 3 个值?
