Dropping/Undropping HTML Text Formatting Tags

Ruby example to demonstrate how text formatting tags (b, font, i, u, br, center, em, strong, big, tt, s, small, strike, sub, and sup) are dropped by default. The UndropTextFormattingTags method prevents the formatting tags from being dropped during conversion.

# file: TextFormattingTags.rb

require 'chilkat'

# Demonstrates how HTML text formatting tags are (by default) dropped
# during the HTML to XML conversion process.  To keep text formatting
# tags, call UndropTextFormattingTags

htmlConv = Chilkat::CkHtmlToXml.new()
success = htmlConv.UnlockComponent("anything for 30-day trial")
if not success
	print "component is locked!"
	exit
end

html = "<html><body>This <b>is</b> a <i>test</i></body></html>"
	
# To convert, set the HTML and get the XML:
htmlConv.put_Html(html)
xml = htmlConv.xml()
	
print xml


#		The output is this:
#		
#		<?xml version="1.0" encoding="utf-8" ?>
#
#		<root>
#		    <html>
#		        <body>
#		            <text>This  is a  test</text>
#		        </body>
#		    </html>
#		</root>
#		
#		
			
# What happened to the <b> and <i> tags???
# By default, text formatting tags are dropped.
# If we call UndropTextFormattingTags, the tags will remain:
htmlConv.UndropTextFormattingTags()
	
xml = htmlConv.xml()

print xml
	
#		We now get this:
#		
#		<?xml version="1.0" encoding="utf-8" ?>
#
#		<root>
#		    <html>
#		        <body>
#		            <text>This </text>
#		            <b>
#		                <text>is</text>
#		            </b>
#		            <text>a </text>
#		            <i>
#		                <text>test</text>
#		            </i>
#		        </body>
#		    </html>
#		</root>
