What version of BIND are you running? XML version 2.2 strikes me as quite old.

Hi its running on CentOS 7 says bind 9.9.4

rpm -qa | grep bind bind-license-9.9.4-29.el7_2.4.noarch rpcbind-0.2.0-33.el7_2.1.x86_64 bind-9.9.4-29.el7_2.4.x86_64 bind-utils-9.9.4-29.el7_2.4.x86_64 bind-libs-9.9.4-29.el7_2.4.x86_64 bind-libs-lite-9.9.4-29.el7_2.4.x86_64

Any thought on this, would love to get this working

[jforman]

9.9.4 is from >2 years ago (https://www.isc.org/blogs/bind-9-9-4-released/). Might you consider upgrading BIND to a version more recent?

To answer your question, the commit you're concerned with is from the library I use underneath Binder to process the BIND status XML (https://github.com/jforman/pybindxml/commit/bba5c1a5f04ecfb4f98000384adb4a74e80dc272). I removed support for <3.0 back in May 2016 as I was cleaning up the code. I'm honestly not to keen on adding it back in, given how old it is, and the added maintenance cost of that code.

Thanks Jeff Seem like RHEL and CentOS only go up to 9.9.4 I think its to do with maintaining long term compatibility. Fedora does go to 9.10. Did think of installing the Fedora rpm's but it can introduce other dependency problems. I'm only testing at the moment so I may build a Ubuntu server instead to try out.

I just find out the reader.py, and edit as below (added the elif fork for version 3.11 ....):

if self.xml_version == '3.0':
            self.stats = XmlV30(self.bs_xml)
        elif self.xml_version == '3.3':
            self.stats = XmlV33(self.bs_xml)
        elif self.xml_version == '3.5':
            self.stats = XmlV35(self.bs_xml)
        elif self.xml_version == '3.6':
            self.stats = XmlV36(self.bs_xml)
        elif self.xml_version == '3.11':
            self.stats = XmlV36(self.bs_xml)
        else:
            raise XmlError('Support must be added before being able to support newly-encountered XML version %s.' % self.xml_version)

you may install pybindxml from https://github.com/Dunedan/pybindxml it has 2.2 compatibility and all works even on centos 7
