deprecatedclass %iKnow.Source.Converter.Html
extends %iKnow.Source.Converter
This is a sample implementation for %iKnow.Source.Converter, designed
to weed out HTML tags from plain text input. Data is first buffered into a process-private
global and stripped of HTML in the Convert call.
Converter parameters:
- Unescape As %Boolean: set to 1 to unescape HTML special
characters such as converting "&" to "&" (default = 1)
- SkipTags As %String: comma-separated list of tags whose content
(text nested between the start and end tag) is to be left out (default = "script,style")
- BreakLines As %Boolean: whether or not to insert double
line breaks for non-inline tags (such as p, br, td, ...), in order for the
iKnow engine to split sentences at those positions (default = 1)
