This option should contain a comma separated list element convertion chunks. Each chunk contains information about how one element and it's attributes should be treated. The default rule set for this option is specified below.
| Control characters: | |
| , | Separates element chunk definitions. |
| / | Separates element synonymous. The first element is the one that will be outputted. |
| | | Separates attribute definitions. |
| [ | Starts a new attribute list for a element definition. |
| ] | Ends a attribute list for a element definition. |
| = | Makes the attribute to default to the specified value. For example "target=_blank" |
| : | Makes the attribute to be forced to the specified value. For example "border:0" |
| < | Verifies the value of a attribute. For example "target<_blank?_self" |
| ? | Separates attribute verification values, see above. |
| + | Makes the element open if no child nodes exists. Example: +a. |
| - | Enables removal of empty elements such as <strong />. Example: -strong. |
| # | Enables padding of empty elements, this will padd with if they are empty. Example: #p. |
| ! | Makes attributes required. If non of the required attribures are set the element will be removed. Example: !href. |
Special variables:
{$uid} Results in a unique ID. For example "p[id:{$uid}]".
Use *[*] to include all elements and all attributes this can be very useful when used with the invalid_elements option.
Example of usage of the valid_elements option:
This example string tells TinyMCE to remove all elements that are not a "a, strong, div or br" element, convert b elements to strong elements, default target to "_blank" and keep the href, target and align attributes of the elements.
tinyMCE.init({
...
valid_elements : "a[href|target=_blank],strong/b,div[align],br"
});
Default rule set:
This is the default string used by TinyMCE to cleanup the HTML contents.
