Merging 2 + XML Documents with different Encoding Types

I have the task of merging 2 XML documents together that differ in their encoding types. One is declared as a UTF-8 (8bit UCS Transformation format) doc, the other the ISO-8859-1 format type (Latin Alpha No. 1). I wanted to do it w/o parsing the xml as well, as that's an expensive operation and with large documents can be problematic. Well, I figured, this is easy! I'll do the following:
  • Create a String Buffer to hold the new Large XML
  • Strip the Root Nodes and any xml header (doctype/?xml etc)
  • Write each xml doc to the String Buffer
  • Append the Root Node Back to the Main String
  • Close the String Buffer
  • Have a snack
XML Doc 1:
<?xml version="1.0" encoding="UTF-8"?>
<jobtitle>Job 1</jobtitle> ...
XML Doc 2:
<?xml version="1.0" encoding="iso-8859-1"?>
<jobtitle>Job 2</jobtitle> ...

Turns out, that only works well if the XML documents you're attempting to merge are of the same encoding type. Any ideas on a work around?

What I did, is I specified an encoding type for a FileWriter object, and followed the same process, but had to write the file to disk specifying a unified encoding type, then read the file back.

This worked ok, but I am looking at alternatives like going to Binary and back to String again, but for now, this is my best available option.

ToScript or not ToScript

Nice little function in CF 7 that I totally overlooked: ToScript

Creates a JavaScript or ActionScript expression that assigns the value of a ColdFusion variable to a JavaScript or ActionScript variable. This function can convert ColdFusion strings, numbers, arrays, structures, and queries to JavaScript or ActionScript syntax that defines equivalent variables and values.


A string that contains a JavaScript or ActionScript variable definition corresponding to the specified ColdFusion variable value.

This can contain one of the following:
  • String
  • Number
  • Array
  • Structure
  • Query
Very useful when assigning cf data to javascript - nice to know now?!


Why the name? Well it's a bit of a play on the BASIC acronym but I thought it would apply fairly well with how I feel about what ColdFusion technology allows us to accomplish.
