The minidom XML support in aravisGigEApp/src/makeDbAndEdl.py fails on parsing the very first part of the XML file.

Can it be that the XML file does not start with a declaration line? Does the support file expect this? Such as:


<?xml version="1.0" encoding="UTF-8"?>

I’m trying to use aravisGigE to drive a Basler acA1920 ethernet camera
with areaDetector. I’m following the instructions at
https://github.com/areaDetector/aravisGigE to add a new camera. As
detailed below, I can get an XML file from the camera, but
makeDbAndEdl.py is not parsing this file. The XML file is large, but the
failure seems to be right at the beginning. Am I doing something stupid,
or is the Basler camera incompatible with aravisGigE?

FIRST TWO LINES OF XML FILE:
