Question

Add "\n" to tags in nested HTML

I need to prepare html for sending via the Postmark API.

Given the following:

<cfset vHTML = "<html><body><div>This is html</div></body></html>">

What would be the cleanest way to arrive at:

<cfset vPostmarkHTML = "<html>\n<body>\n<div>This is postmark html</div>\n</body>\n</html>">

i.e. surround every nested tag group with "\n" except the outer <html> group

    <cfset vHTML = "<html><body><div>This is a div.</div><div>This is a second div.</div></body></html>">

<!--- Test both versions of line-feed, and see which fits your needs. --->
<!---<cfset LF=chr(10)>--->
<cfset LF="\n">


<cfset vPostmarkHTML = vHTML.replaceNoCase("<body>","#LF#<body>").replaceNoCase("<div>","#LF#<div>","all").replaceNoCase("</body>","</body>#LF#").replaceNoCase("</div>","</div>#LF#","all")>

<cfoutput>
	<strong>vPostmarkHTML</strong><br>
	#vPostmarkHTML#
</cfoutput>
