在GSP中呈现HTML

Question

I have some content in database table (blog post) that is trusted content and I want to display on screen. This content is HTML and has some code samples using Prism.js for syntax highlighting. Because of the HTML econding on a gsp page I need to use the raw method to output the content as is

${raw(post.content)}

This works great except for when I get to the code that is wrapped in a tags for my code samples. Instead of showing it as code its outputting the raw html which is not what I want. I somehow need to encode the text that is inside of there because If I don't I end up with something that looks like this.

I know that I could do the encoding on save but I already have hundreds of posts where this is not the case. Any ideas?

Answer 1

In my case I had to grab the raw content in the view

${raw(post.getEscapedContent())}

and then in the domain object I escaped anything inside of the code blocks

/**
 * I will return the content of a post with the necessary html escaping. To render html in code blocks we
 * need to escape any html inside of <code></code>
 * @return String
 */
def getEscapedContent(){
    content.replaceAll(/(?ms)(<code.*?>)(.*?)(<\/code>)/) { it, open, code, close ->
        open + code.encodeAsHTML() + close
    }
}
