- com.sencha.gxt.core.shared.ExpandedHtmlSanitizer

All Implemented Interfaces:

com.google.gwt.safehtml.shared.HtmlSanitizer
```
public final class ExpandedHtmlSanitizer
extends Object
implements com.google.gwt.safehtml.shared.HtmlSanitizer
```
An expanded HTML sanitizer based on SimpleHtmlSanitizer, but with a larger set of formatting tags that make this sanitizer more useful. These tags were determined to be safe by conducting a manual review of formatting tags that don't require attributes to be useful from the full list of tags at: http://www.w3schools.com/tags/
This sanitizer accepts only the following subset of HTML tags and only when used with no attributes:
- <b>, <big>, <del>, <em>, <i>, <ins>, <mark>, <s>, <small>, <strike>, <strong>, <sub>, <sup>, <u>
- <br>, <div>, <center>, <hr>, <p>, <span>
- <h1>, <h2>, <h3>, <h4>, <h5>, <h6>
- <dd>, <dir>, <dl>, <dt>, <li>, <ol>, <ul>
- <address>, <article>, <aside>, <blockquote>, <cite>, <code>, <details>, <dfn>, <footer>, <header>, <kbd>, <main>, <pre>, <q>, <samp>, <section>, <summary>, <tt>
- <table>, <tbody>, <td>, <tfoot>, <th>, <thead>, <tr>
- <bdi>, <rp>, <rt>, <ruby>, <wbr>
as well as numeric HTML entities and HTML entity references. Any HTML metacharacters that do not appear as part of markup in this subset will be escaped.
