Regular Expression question

[Mark Schonewille]

Ron,

When you do a search, you're not searching for text. You're searching  
for *binary data*. So, find out what the binary data is and make a  
regex for that. If there are any characters with a special meaning,  
escape them.

Also bear in mind that when doing matchChunk, you'll get the positions  
in the binary string, which is not the same as the number of the  
character in a field, because one character can consist of up to 4  
bytes.
