HL7 and Xlate

[garry r fisher]

Hi,

I’ve got an HL7 message and I’m trying to extract a field 4 in the QRF message:

.QRF||||SEX^~DOB^||||

I’m doing this is an xlate copying into a temporary variable. I’m then want to split the field on the ~ and check for a SEX code or DOB after each ^. Unfortunately when I use a xlate Tcl to read the temporary value all I get is SEX (no silly comments please). I’m using xlateInVals, should I use xlateInList or am I doing something wrong in trying to parse HL7 this way.

Thanks

Garry

I’m not sure what your groups look like for your xlate but you’re going to have to reference the second itteration of that field.  The ~ represents a repeating field and since the DOB is in the second iteration you’ll have to reference the second iteration in your xlate.

Like I said, I’m not sure what your varient looks like but it would be something like this:

0(0).QRF.00098(1)

(in your source just put the (1) after the field numbers to reference the second iteration of that field)

Check your temp variable copy first.

Hi,

I’ll give those suggestions a go on Monday. You are correct there are no subfields defined – that is why I thought a simple copy would suffice.

Enjoy your weekend.
