I have XML::XPath and XML::XPath::XMLParser installed on my Raspberry PI. uname identifies the OS as armv7l GNU/Linux. I do not use the other two modules.

Now, I run a custom-built Perl and installed these using the CPAN client. If you are using the system Perl, you will either have to figure out which OS packages to install (if they are in fact available), or figure out how to make a local::lib installation.

When I tried XML::CanonicalizeXML, it failed for a missing library. This does not mean it can not be done, it just means I need to figure out what else needs to be installed to support it. Crypt::OpenSSL::RSA pulled in a few other modules, but tested successfully on my Raspberry PI, meaning that it could be installed and used.

Summary of my personal experience:

• XML::CanonicalizeXML - No relevant experience;
• XML::XPath - Yes;
• XML::XPath::XMLParser - Yes;
• Crypt::OpenSSL::RSA - Almost certainly yes.

Note that XML::XPath::XMLParser is part of the XML-XPath distribution. If you can get XML::XPath, you should get XML::XPath::XMLParser along with it.
