markdowntosail function

Question

Hi, 
 I am trying to convert HTML I receive from a web service in to rich text. 
 I have tried using the markdowntosail function found in Markdown to SAIL (v1.0.0) [com.appiancorp.ps.plugins.richtexttools] component and using it on 20.1 
 The purpose is to ensure I retain URL's that are held within the HTML. 
 Any other ideas/guidance would be greatly appreciated. 
 Thanks!

I thought I'd ended up posting this somewhere but after this long I have no idea... so i'll attach it below: /* rule!GLBL_CMPT_RichTextHTMLPreview */ a!localVariables( local!formatBreakdown: rule!GLBL_UTIL_GetParsedRichTextBreakdown(htmlText: ri!htmlText), a!richTextDisplayField( label: ri!label, labelPosition: rule!GLBL_replaceNull(ri!labelPosition, "COLLAPSED"), instructions: ri!instructions, showWhen: ri!showWhen, value: { a!forEach( local!formatBreakdown, a!richTextItem( text: rule!GLBL_UTIL_FormatHTMLLinebreaksForTextDisplay( htmlText: fv!item.row ), style: { fv!item.formats }, link: a!safeLink( uri: fv!item.link, showWhen: not(rule!GLBL_isBlank(fv!item.link)) ) ) ) } ) ) /* rule!GLBL_UTIL_GetParsedRichTextBreakdown */ a!localVariables( local!formatChangeMarker: "[[[formatChange]]]", local!test: regexreplaceall( pattern: "(<[biu]>|)", searchstring: ri!htmltext, replacementString: local!formatChangeMarker & "$1" ), local!array: split(local!test, local!formatChangeMarker), local!formatMarks: a!forEach( local!array, tostring( if( left(fv!item, 8) = "") & "}}", extract( left(fv!item, 4), "<", ">" ) ) ) ), a!forEach( local!formatMarks, with( local!list: joinarray(index(local!formatMarks, enumerate(fv!index)+1), ";"), local!list1: regexreplaceall( "b(.+?)/b", local!list, "$1"), local!list2: regexreplaceall( "i(.+?)/i", local!list1, "$1"), local!list3: regexreplaceall( "u(.+?)/u", local!list2, "$1"), local!list4: regexreplaceall( "a\{\{.+?\}\}(.+?)/a", local!list3, "$1"), { row: regexreplaceall("<[bui]>||", local!array[fv!index], ""), formats: touniformstring( a!forEach( rule!GLBL_UTIL_removeBlankValuesFromArray( trim(split(local!list4, ";")) ), if( fv!item = "i", "EMPHASIS", fv!item = "b", "STRONG", fv!item = "u", "UNDERLINE", left(fv!item,1) = "a", {}, "" ) ) ), link: tostring( rule!GLBL_UTIL_removeBlankValuesFromArray( touniformstring( a!forEach( trim(split(local!list4, ";")), extract(fv!item, "a{{", "}}") ) ) ) ) } ) ) ) /* rule!GLBL_UTIL_FormatHTMLLinebreaksForTextDisplay */ a!localVariables( local!lineBrokenText: regexreplaceall( "
", substitute( substitute(ri!htmlText, char(13), ""), char(10), "" ), char(10) ), local!lineBrokenText ) Note that this is 3 separate expression rules; also they make use of a few helper expression rules (like "ReplaceNull" and "RemoveBlankArrayMembers") that you may need to implement yourself in your own system and swap in for the rules named in these.

In the past I've written out-of-box Appian expression rules that parse certain simple HTML formatting to display in Rich Text on an Appian form (read-only of course). It only supports bold, italic, underline, linebreaks, and hyperlinks. If that sounds like enough for you, then I could dig up and attempt to post them here. Note it also does require the Regex Utilities plug-in.
