Hi @Soojung.Kim,
After changing the .pkt to a .zip and unzipping it, you could try parsing the .emd file using the standard Python ElementTree module since it is formatted as an XML. Here’s an example:
import xml.etree.ElementTree as ET
file_name = IN[0]
attributes=[]
xml = ET.parse(file_name)
root = xml.getroot()
for group in root.iter('EnumItem'):
attributes.append(group.attrib)
OUT = attributes
