%iKnow.Source.Converter.Html

class %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:

  1. Unescape As %Boolean: set to 1 to unescape HTML special characters such as converting "&" to "&" (default = 1)
  2. 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")
  3. 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)
