Tag Filter

This filter can delete HTML elements and change element attributes.

Parameters

tag

The tag parameter defines HTML element and modifying action.

Format:

tag = tagname:action

tagname – specifies HTML element's name (e.g. blink).
action – defines action to apply to the specified element.

Possible action values:

• strip – delete both opening and closing (if present) tags.
• delete – delete opening and closing tags and everything in between.
• delattr name – delete attribute name if present.
• setattr name "value" – set attribute name to "value". The quotes may be omitted if the value does not contain spaces.

Note: Be careful with the delete action. If there is no closing tag, the rest of the document will be deleted.

See also Common Filter Parameters.

Example

The following filter strips <blink> and <marquee> tags. For instance, a fragment like “<blink>Blinking text</blink>” will be converted to “Blinking text”:

type = Tag Filter
name = Blink and Marquee Stripper
enabled = true
logging = true
include = *
tag = blink:strip
tag = marquee:strip

Example 2

The following filter makes sure that all frames are resizable:

type = Tag Filter
name = Resizable Frames
enabled = true
logging = true
include = *
tag = frame: delattr "noresize"
tag = frame: delattr "frameborder"
tag = frame: delattr "scrolling"
tag = frameset: delattr "frameborder"
tag = frameset: delattr "framespacing"
tag = frameset: delattr "border"
