How to parse multiple DG1 segments in HAPI?

I would like to know if there is a standard way of using the terser for parsing hlv2 messages?

terse.get("/.DG1(i)-4") //Works
terser.get("/.PROCEDURE(i)/PR1-3-2") //Works
terser.get("/.PR1(i)-3-2") //Does not work.

What is the difference and is there documentation of how to use the terser with respect to the different segments?

You need to specify the whole path of the segment, you can't leave anything out.

Like you said this works:

terser.get("/.PROCEDURE(i)/PR1-3-2") //Works

So this should work too:

terser.get("/.PROCEDURE(i)/PR1(1)-3-2")

But if you want to access all PR1 in any segments (not just PROCEDURE) you need to tell that with a *:

terser.get("/*(i)/PR1-3-2")

Documentation and samples you can find here http://hl7api.sourceforge.net/apidocs/ca/uhn/hl7v2/util/Terser.html
