I need to be able to run the contents of a field through a filter that strips out characters that are illegal in a 3rd party xml and return a dialogure that tells the user what the bad character is. Right now what I am doing is setting a variable $variableBefore = Count ( field ) the I run it through a filter that contains all acceptable characters. I then take the results of that filter and set a variable $variableAfter = Count ( ScriptResult ). Then I ask, if $variableBefore > $variableAfter Custom Dialoge [ There is an illegal Charater... blah, blah, blah ] I want to compare:
$variableBefore & $variableAfter
So I can see what the difference is so i ca alert the user as to what the bad character is.
Can anyone help?
