Html Whitelist
Introduction
This library can be used to whitelist html elements, attributes and attribute values.
The main purpose is to process html from an untrusted source and make sure that if the html is rendered by your application it doesn't contain elements that are not safe.
Usage
import 'package:htmlwhitelist/htmlwhitelist.dart';
main() {
var contents = '<b>See:</b> <a href="docs.html">the documentation</a>';
var safe = Whitelist.simpleText.safeCopy(contents);
print(safe);
}
prints
<b>See:</b> the documentation
If you have a DocumentFragment instead of a String you can use the Cleaner instead:
import 'package:htmlwhitelist/htmlwhitelist.dart';
import 'package:html/parser.dart';
import 'package:html/dom.dart';
main() {
var contents = '<b>See:</b> <a href="docs.html">the documentation</a>';
DocumentFragment fragment = parseFragment(contents);
DocumentFragment safeCopy = Whitelist.simpleText.cleaner.safeCopy(fragment);
print(safeCopy.outerHtml);
}
prints
