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. PowerBuilder

integer li_rc
string s
oleobject loo_Sb
integer li_NumReplaced

// We have the following string with some us-ascii chars escaped like this:
s = "\x7b\x22responseContext\x22:\x7b\x22"

// 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..

loo_Sb = create oleobject
li_rc = loo_Sb.ConnectToNewObject("Chilkat.StringBuilder")
if li_rc < 0 then
    destroy loo_Sb
    MessageBox("Error","Connecting to COM object failed")
    return
end if

loo_Sb.Append(s)
li_NumReplaced = loo_Sb.Replace("\x","\u00")

// Now decode from "json" escapes
loo_Sb.Decode("json","utf-8")

// Show the decoded string
Write-Debug loo_Sb.GetAsString()

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


destroy loo_Sb
