OK - changing parameters a bit here. The initial data is all on one line, with key/value pairs seperated like this:

 

cn=JoeAgent | Intradoc_Hrchy_Tx=somevalue | first_nm=Joe | last_nm=Agent | de3fault_agnt_id=123fake | EMAIL_ADR=agentjoe@fake.org

 

 

The keys and variables may change without notification - so hardcoding them in as a static::field is less than ideal. The initial data is already stored as a variable (let's say it's $attributes).

 

We can split the $attributes into records based on "|", and then split the records into fields based upon "=".

 

Where I'm getting stumped is populating a table with those fields. How do I get it to look something like this:

 

key | value

 

$field1 | $field2

 

$field3 | $field4 etc.

 

 

I can then pull the data from the table, because I'll know the key name that I'm looking for when I need to pull it back from the table- so I can do a

 

table lookup $field3

 

for example, substituting the value of $field3 and getting the $field4 value returned.

 

Any help would be appreciated.
