使用HTML访问深度嵌套的数据使用Python标记

Question

因此，我试图从具有深层嵌套<script>标签的网站中获取特定数据。

使用import json，希望能使事情变得容易一些，导致出现著名的Expecting value: line 1 column 1 (char 0)错误。因此，我尝试了以下方法1，但成功率为零。

实质上，连接到站点的相对简单步骤，捕获特定的<script>标记是没有问题的。从我需要的数据中获取数据似乎有问题。

假设以下元素：

script_tag = '''
<script id="startup" type="text/javascript">
$(document).ready(function () {createJsonChart({
"series":[{"name":"BNames","color":"#0043de","legendIndex":0,
"stack":null,
"data":[{"name":"BNames","color":"#0043de","y":0.0,
"legendIndex":0,
"events":{"click":function(){return false;}},
"subtotal":0.0,"displayValue":"0","tooltip":""},
{"name":"BNames","color":"#0043de","y":114.6,
"legendIndex":0,
"events":{"click":function(){return false;}},
"subtotal":0.0,"displayValue":"0",
"tooltip":"BNames: 114,60 % <br/> Month: oktober 2018"},
{"name":"BNames","color":"#0043de","y":108.5,
"legendIndex":0,
"events":{"click":function(){return false;}},
"subtotal":0.0,"displayValue":"0",
"tooltip":"BNames: 108,50 % <br/> Month: september 2019"},
{"name":"BNames","color":"#0043de","y":0.0,
"legendIndex":0,
"events":{"click":function(){return false;}},
"subtotal":0.0,"displayValue":"0","tooltip":""}]},
{"type":"line","marker":{"enabled":false,
"linecolor":null,"lineWidth":0,
"fillColor":null,"symbol":null,"radius":4},
"dashStyle":"Solid","lineWidth":2,
"step":"center","zIndex":"2","name":"Mandatory","color":"#f20808",
"legendIndex":0,"stack":1,
"data":[{"name":"Mandatory","color":"#f20808","y":104.1,
"legendIndex":0,
"events":{"click":function(){return false;}},"subtotal":0.0,"displayValue":"0",
"tooltip":"Mandatory: 104,10 %: 104,10 %"},
{"name":"Mandatory","color":"#f20808","y":104.1,
"legendIndex":0,
"events":{"click":function(){return false;}},
"subtotal":0.0,"displayValue":"0",
"tooltip":"Mandatory: 104,10 %"},
{"name":"Mandatory","color":"#f20808","y":104.1,
"legendIndex":0,
"events":{"click":function(){return false;}},
"subtotal":0.0,"displayValue":"0",
"tooltip":"Mandatory: 104,10 %"}]},
{"type":"line","marker":{"enabled":false,
"linecolor":null,"lineWidth":0,"fillColor":null,
"symbol":null,"radius":4},"dashStyle":"Solid","lineWidth":2,
"step":"center", "zIndex":"2","name":"Preferred","color":"#38d615",
"legendIndex":0,"stack":2,
"data":[{"name":"Preferred","color":"#38d615","y":121.0,
"legendIndex":0,
"events":{"click":function(){return false;}},"subtotal":0.0,"displayValue":"0",
"tooltip":"Preferred: 121,00 %: 121,00 %"},
{"name":"Preferred","color":"#38d615","y":121.0,
"legendIndex":0,
"events":{"click":function(){return false;}},"subtotal":0.0,"displayValue":"0",
"tooltip":"Preferred: 121,00 %"},
{"name":"Preferred","color":"#38d615","y":121.0,
"legendIndex":0,
"events":{"click":function(){return false;}},"subtotal":0.0,"displayValue":"0",
"tooltip":"Preferred: 121,00 %"}]}],
"resizeElement":null,"credits":{"enabled":false}});$('#__Page').lumnaInit('');});
</script>
'''

实际上，此<script>标签更大。它包含3个部分的数据，此处分别命名为BNames，Mandatory和Preferred。我需要BNames中的数据，特别是最后一个条目。因此，预期结果将来自部分"tooltip":"BNames: 108,50 % <br/> Month: september 2019"}，其中一个变量为BNames: 108,50 %，另一个变量为Month: september 2019。

Answer 1

不确定您的最终用例，但以下正则表达式会否以正确的方向启动您？匹配BNames字符串。
