I’m having a problem using a Terser on a GenericMessage with repeating NTE
segments.
I whipped up a test case to show the issue. Why does the terser getter like
“NTE2-3-1” work while “NTE(1)-3-1” fail? Is there any way to make the latter
format work?
@Test
public void testNTEQuirk() {
String hl7Message = null;
try {
hl7Message =
resourceUtil.getResourceAsString("nte_quirk.hl7");
} catch (IOException e) {
fail("Could not load resource!");
}
GenericMessage message = new
GenericMessage.UnknownVersion(new DefaultModelClassFactory());
try {
message.parse(hl7Message);
} catch (EncodingNotSupportedException e) {
e.printStackTrace();
throw new RuntimeException("Could not parse
HL7 message! Encoding not supported.", e);
} catch (HL7Exception e) {
e.printStackTrace();
throw new RuntimeException("Could not parse
HL7 message!", e);
}
Terser terser = new Terser(message);
//"/." + segment + "(" + index + ")-" + field + "-" +
component;
try {
//why do the next 3 lines work??
assertEquals("OBRnotes",
terser.get("/.NTE2-3-1"));
assertEquals("OBX",
terser.get("/.NTE3-3-1"));
assertEquals("notes",
terser.get("/.NTE4-3-1"));
assertEquals("ORCnotes",
terser.get("/.NTE(0)-3-1"));
//why do these lines fail??
assertEquals("OBRnotes",
terser.get("/.NTE(1)-3-1"));
assertEquals("OBX",
terser.get("/.NTE(2)-3-1"));
assertEquals("notes",
terser.get("/.NTE(3)-3-1"));
} catch (HL7Exception e) {
fail();
}
}
