Java 解析过程中的CSSOMParser错误

我在解析css文件时遇到以下错误

它看起来与损坏的css标记有关。有人能澄清一下吗？ 我正在使用文件中的css规则来找出html页面上链接到css的某些元素。这些错误是否会影响css规则的解析，从而影响网页上html元素的分析？我肯定是这样，但希望不是这样

提前感谢。

解析时必须转义字符。Apache有StringEscapeUtils类可以帮助您。 我认为你必须使用StringEscapeUtils.escapehtmlreadtext；由于html和css语法更相似

问候

可能是因为您正在使用非标准CSS规则，例如！ie7或特定于供应商的属性，如-moz border radius

所以这是一个问题，我不应该担心规则被忽略，因为它们可能非常特定于供应商？？我说的对吗？我认为这不会给你带来问题。OP正在解析一个独立的CSS文件，所以不需要转义HTML实体。
