Unfortunately, while you can use back-references to return a portion of a
found regular expression back to the replacement, you can't use any kind of
functions or conditional logic on these back-references, so you'd have to
replace each character individually... As for actually getting the illegal
characters, try something like this:
<cfset illegalchar = REFind(">[^<]*?[^ _-\.[:alnum:]][^<]*?",myxmlpacket)>
This should give you the location of the first illegal character in the
packet, within the contents of an element, assuming that an illegal
character is anything other than a space, underscore, hyphen, dot or
alpha-numeric character... That's probably not a real good definition for
illegal characters, but it's a starting point. :)
Once you know where that character is, then you can replace it with
something like <char=#asc(illegalcharacter)#> or whatever the spec. is for
special characters in your xml dtd. Am I using the terminology correctly?
