Filter all elements except b, convert filtered elements to space
December 13, 2011 01:26PM

I'm having a small issue where I have minified HTML, that I now need to strip out all tags except for the 'b' tag when it has the class 'red'. I am able to pretty easily do this with this config

'HTML.Allowed', 'b[class]'

'Attr.AllowedClasses', 'red'

Since my HTML text is minified, the output looks something like this

::input:: <p><ul><li>item</li><li><b class="red">item2</li></ul></p> ::output:: item<b class="red">item2</b> When when rendered, looks like, "itemitem2"

Since them items are block level elements, is there a way to add a space between them? So the output would look like,

::output:: item <b class="red">item2</b>

Yeah, this is a kind of known lacking feature One possible thing to do is to preprocess the HTML to add the extra spaces necessary before tossing it at HTML Purifier.

HTML input is enabled. Make sure you escape all HTML and angled brackets with &lt; and &gt;.

Auto-paragraphing is enabled. Double newlines will be converted to paragraphs; for single newlines, use the pre tag.

Allowed tags: a, abbr, acronym, b, blockquote, caption, cite, code, dd, del, dfn, div, dl, dt, em, i, ins, kbd, li, ol, p, pre, s, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, var.

For inputting literal code such as HTML and PHP for display, use CDATA tags to auto-escape your angled brackets, and pre to preserve newlines: 

<pre><![CDATA[
