How do use the regular expression for the pattern value constraint to impose a restriction that the element should not start or end with a colon?
I can do it at the ESQL level ,but can I not impose that in the message set? |

Hi,
I am assuming that Colons will always come in the message,
and the data may be like ":data:"
U cannot Ignore the Colons. What u shoud do is store the begining colon in one Element(EL_COL1) in the message and the ending Colon(EL_COL2) in One element in the message and the content between the Colons in Another Variable(Field1).
First Create a Compound Type(CTYPE), with Data Element Separation Property to Data Pattern. Now, Create the elements Described above under this CTYPE in the following order:EL_COL1,FIELD1,EL_COL2. Field1 will contain the Data that u r looking for.
Now, For all the 3 elements, EL_COL1,FIELD1,EL_COL2, use the datapattern at the element level as follows.
fOR EL_COL1,set the data pattern to ':' .
for FIELD1, set the data pattern is [^:]* (this stands for anything until a colon comes)
for EL_COL2, set the data pattern is ':'.
If this is Confusing, Please let me know..
Thanks,
Raja

I used this pattern [a-zA-Z0-9/\?\(\)\.,'\+\{\} ]([a-zA-Z0-9/\-\?:\(\)\.,'\+\{\} ]*[^\-])*
and it worked!
Thanks |
