Class Method Details

._sanitise_html(html, regex, replacement) ⇒ Object

Sanitise HTML string but only when the regex to be replaced actually exists. The intention for sanitising the HTML is to strip out unused invalid HTML tags, so that the remaining HTML is valid for rexml to parse. It’s important to not assume that the regex exists due to the possibility of future AEM versions to produce a different response body that might / might not contain the invalid HTML tags on the older AEM versions.

Parameters:

  • html

    HTML response body string

  • regex

    Ruby regular expression, all regex matches will be replaced

  • replacement

    all existence of the regex will be replaced with this string
