Let's say I've got a set of strings being drawn from a database that look like this:
"This is a test<stro" (NEEDS TRIMMING)
"This is a test 2 Hi." (GOOD)
"This is a test 3</i" (NEEDS TRIMMING)

I want to trim my results so that the two strings with incomplete HTML become:
"This is a test" (TRIMMED)
"This is a test 3" (TRIMMED)

So basically I want to trim off from "<" to the end of my string, but only in the situation that a finalizing ">" is not present.

Normally I would think to make my strings into a list delimited by "<" and then removing the last item, but that would also trim all the GOOD statements that have terminating ">"'s.

Can someone lead me in the right direction? I've been scratching my head over this for a couple of days.

Thanks,
Sam

<cfscript>
strings = arrayNew(1);
strings[1] = structNew();
strings[1].old = "This is a test<stro";
strings[2] = structNew();
strings[2].old = "This is a test 2 Hi.";
strings[3] = structNew();
strings[3].old = "This is a test 3</i";
strings[4] = structNew();
strings[4].old = "This is a test 4<";

for (i=1; i LTE arrayLen(strings); i=i+1) {
strings .new = rereplace(strings.old, '\<([^\>]+)?$', '');
}

</cfscript>

I guess I'll have to do some kind of cfscript, my problem is not the removal of bad tags though, but having incomplete tags in my strings

The user is limited to the number of characters that can be displayed, I dont want it to chop off in the middle of an HTML tag

I need some kind of loop that scans the string and checks for a finalizing >, and then removes all text up to the previous <
