escape

HTML escape a text. Escapes all reserved HTML characters in the value. Escaped strings are safe to be displayed in a HTML page. When you echo a query string argument or path variable then you must escape the value before displaying it on a HTML page.

The following characters are replaced:

Character	Replacement
>	>
<	&lt;
"	&quot;
'	&#039;
&	&amp;

The escaping is only applied when the string is output, so it does not matter where in a chained sequence of filters you put escape: it will always be applied as though it were the last filter. If you want escaping to be applied immediately, use the force_escape filter.

For example:

{{ value|escape }}

When the value is <hel&lo> then the output is &lt;hel&amp;lo&gt;.

Note: this filter is not part of a module, it is built into ErlyDTL.
