如何逃避成为字符串一部分的斜杠？

Question

Im having difficulty finding a way to escape these quotes,

String key = StringUtils.substringBetween(html, "class=\"category_keyword\"", ">");

Specifically this part:

"class=\\"category_keyword\\""

How the heck do I escape the quotes in ( \\"category_keyword\\" ) while keeping the slashes?

Those slashes are not for escaping they are part of the string. Yet when i add another (to escape the quote), Eclipse thinks I'm escaping the slash next to it.

Im sorry if this is a bit confusing, let me know if i could be more clear.

Answer 1

You can simply do: \\\\\\"category_keyword\\\\\\"

\\\\ => You are escaping the slash \\

\\" => You are escaping the quote "

public class Class{
    public static void main(String[] a){
        System.out.println(" \\\"Ferrari\\\" ");
    }
}

Answer 2

如果你想保留斜线但是要转义引号：

\\\"category_keyword\\\"
