Hi Steve,
nice to hear from you.
I’m sorry that I cannot run the CentroidPy by now, nevertheless when I saw your request I noticed something strange: ComplexeData contains a XML content, which sounds good but there is also a <![CDATA[XML]]> which looks odd.
So I tried to remove it, just to make sure this request will then work correctly. Hopefully it was working, note that I used the latest ZOO-Kernel version available on ZOO-Project.org web site.
So that was the way I tried your request with success:
curl -H "Content-Type: text/xml" -d@/Users/djay/MapMint/zoo-project-1.4.0/zoo-project/testing/demo1.xml "http://zoo-project.org/cgi-2014/zoo_loader.fcgi"
You can find attached to this email the XML POST request I used to run my request. I guess you may have better result by adapting this file to your need.
I hope to hear back from you,
Best regards,
