[xwiki-users] Fetching some external XML resource and using it in a XWiki page?

Hello, (warning n00b question ahead) I would like to fetch external data, in xml (say for example https://raw.githubusercontent.com/xwiki/xwiki-commons/master/pom.xml) and use it in a XWiki page : filter tokens, display node contents, etc. At this stage I don’t envision populating a custom class. Would you guys have pointers/examples of such xwiki page? Thank you in advance! Sylvain
