Subject: Proper way to check for successful subexpression match?
Hi,
What needs to be in place of "whatGoesHere" in the following code
block? I'd like to know the proper way to determine whether or not my
subexpression was matched. If you just refer to the structure elements
pos and len, when there is no match, CF throws an error.
// find pattern and return subexpressions
lNameStrc = refind('([^ ]+)$', name, 1, 'true');
// if subexp was found, set var. otherwise set var to bogus val
if (whatGoesHere???) {
lName = mid(name, lnameStrc.pos[2], lnameStrc.len[2]);
} else {
lName = '1029384756XXX';
}
