We are converting some application servers over from CF5 to CFMX and have run into some issues with the way CFMX generates WDDX packets differently then CF5. This is causing a problem with some servers that share the WDDX packet using a central database. The problem arises when an element of a structure has no value. CF5 creates the node as:
<data></data>
While CFMX creates the node as:
<data />
The problem is that CF5 does not recognize the single tag syntax and bombs out. I was working on a Regular Expression to find these single tags. The following works in VB:
<(\w)+\s/>
And because I need it to work on CF5 I tried using the character classes:
<(:alnum:)+\s/>
Neither work. But basically, I want to find any tag in the format of:
<tag />
So I can replace it with the tag in the format of:
<tag></tag>
Here is a quick test page I threw together:
<cfsavecontent variable="VARIABLES.strBad
<data />
<data/>
<data with="attribute" />
<good>data</good>
<goodData with="attribute">data</goo
</cfsavecontent>
<cfset VARIABLES.strRE = "<(\w)+\s/>"><!--- Good Expression that works in VB --->
<cfset VARIABLES.strRECF5 = "<(:alnum:)+\s/>"><!--- <(:alnum:)+\s/> --->

Anyone have ideas on where I am going wrong with the expression?

You typed <data/> in your example. It has no whitespace, so the regex should be <(\w)+\s?/>
BTW, \w is recognized by CFMX as well. No need for (:alnum:)
