通过漂亮的汤蟒找到所有字体大小比最常见的跨度样式 [英] Find all the span styles with font size larger than the most common one via beautiful soup python

问题描述

我理解如何从这个问题中获取特定 div 或 span 样式的文本：如何找到最多常见的跨度样式

I understand how to obtain the text from a specific div or span style from this question: How to find the most common span styles

现在难以找到所有字体大小比最常见的跨度样式？

Now the difficulty is trying to find all the span styles with font sizes larger than the most common one?

我怀疑我应该使用正则表达式，但首先我需要提取特定最常用的字体大小？

I suspect I should use regular expressions, but first I need to extract the specific most common font size?

另外，当条件是字符串时，如何确定大于？

Also, how do you determine "larger than" when the condition is a string?

        fontSize = re.findall("font-size:(\d+)px",styleTag)
        usedFontSize.append(int(fontSize[0]))
