Lua

Decode 2-digit Hex Escaped

See more HTML-to-XML/Text Examples

Demonstrates how to replace escaped us-ascii chars such as \x7b and \x22 with the chars. Lua

local chilkat = require("chilkat")

-- We have the following string with some us-ascii chars escaped like this:
local s = "{\"responseContext\":{\""

-- Note: The above escaping does not conform to any standard format (as far as I know).
-- Chilkat does not have anything to decode from the above.
-- However, we can 1st transform into a standard format, and then decode..

-- JSON escapes chars outside us-ascii like this:  "Hello, \ud83d\ude03!"
-- We can transform the above to this:  "\u007b\u0022responseContext\u0022:\u007b\u0022"
-- And then decode..

local sb = chilkat.StringBuilder.new()

sb:append(s)
local numReplaced = sb:replace("\\x", "\\u00")

-- Now decode from "json" escapes
sb:decode("json", "utf-8")

-- Show the decoded string
print(sb:get_as_string())

-- Here's the result: {"responseContext":{"
