Drop/Undrop Text Formatting Tags

See more HTML-to-XML/Text Examples

Demonstrates how the DropTextFormattingTags and UndropTextFormattingTags methods work in the Html-to-Xml API. Lua

local chilkat = require("chilkat")

-- This example assumes the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local html = "<html><body><p><b>Hello</b> World!<p>This is a test</body></html>"

-- Convert the above to XML
local h2x = chilkat.HtmlToXml.new()

-- By default, text formatting tags are dropped. Text formatting HTML tags are: b, font, i, u, br, center, em, strong, big, tt, s, small, strike, sub, and sup
h2x.html = html
print(h2x:to_xml())

-- The resulting XML is:

-- <?xml version="1.0" encoding="utf-8"?>
-- <root>
--     <html>
--         <body>
--             <p>
--                 <text>Hello World!</text>
--             </p>
--             <p>
--                 <text>This is a test</text>
--             </p>
--         </body>
--     </html>
-- </root>

-- To preserve text formatting tags, put the h2x instance into the mode where text formatting tags are not dropped:
h2x:undrop_text_formatting_tags()

-- Convert again to see the difference:
print(h2x:to_xml())

-- The resulting XML is:

-- <?xml version="1.0" encoding="utf-8"?>
-- <root>
--     <html>
--         <body>
--             <p>
--                 <b>
--                     <text>Hello</text>
--                 </b>
--                 <text> World!</text>
--             </p>
--             <p>
--                 <text>This is a test</text>
--             </p>
--         </body>
--     </html>
-- </root>

-- Call DropTextFormattingTags to put the h2x instance back in "drop" mode.
h2x:drop_text_formatting_tags()

-- Convert again to see the difference:
print(h2x:to_xml())

-- The resulting XML is:

-- <?xml version="1.0" encoding="utf-8"?>
-- <root>
--     <html>
--         <body>
--             <p>
--                 <text>Hello World!</text>
--             </p>
--             <p>
--                 <text>This is a test</text>
--             </p>
--         </body>
--     </html>
-- </root>
