XML parser for Docker container

[lazaa32]

Description

I have a problem with xml parsing when using alpine/flask Dockerfile (the only minor change is upgraded Xerces version to 3.2.1 and added curl package to apk). After building and starting a container I tried to send sample POST request using curl from within the running container but I got ExceptionError:Start tag expected, '<' not found, line 1, column 1</ows:ExceptionText>

Environment

Docker alpine/flask

• operating system:
• Python version:
• PyWPS version:
• source/distribution
  • [ ] git clone
  • [ ] Debian
  • [ ] PyPI
  • [ ] zip/tar.gz
  • [ ] other (please specify):
• web server
  • [ ] Apache/mod_wsgi
  • [ ] CGI
  • [ ] other (please specify):

Steps to Reproduce

Check if Xerces version in alpine/flask Docker file is updated to 3.2.1. Add curl to apk packages. Then:

docker build -t flask .
docker run -it  flask
docker exec -it $(docker ps -aq) /bin/bash
curl -d pywps-flask/static/requests/execute_buffer_post.xml localhost:5000/wps

Additional Information

I also tried to use OWSLib to send the request and I get the result code but the output in response is not well-formated:

Fixed by updating to current pywps version.
