Regex which matches URN by rfc8141

问题 I am struggling to find a Regex which could match a URN as described in rfc8141. I have tried this one: \A(?i:urn:(?!urn:)(?<nid>[a-z0-9][a-z0-9-]{1,31}):(?<nss>(?:[a-z0-9()+,-.:=@;$_!*']|%[0-9a-f]{2})+))\z but this one only matches the first part of the URN without the components. For example lets say we have the corresponding URN: urn:example:a123,0%7C00~&z456/789?+abc?=xyz#12/3 We should match the following groups: NID - example NSS - a123,0%7C00~&z456/789 (from the last ':' tll we match '

问题 I'm trying to do a find all from a Word document for <v:imagedata r:id="rId7" o:title="1-REN"/> with namespace xmlns:v="urn:schemas-microsoft-com:vml" and I cannot figure out what on earth the syntax is. The docs only cover the very straight forward case and with the URN and VML combo thrown in I can't seem to get any of the examples I've seen online to work. Does anyone happen to know what it is? I'm trying to do something like this: namespace = {'v': "urn:schemas-microsoft-com:vml"} results

Why is URN one of more popular formats used to uniquely identify the resource?

问题 I somewhat understand that URNs are used to provide unique and location independent name for the resource. Yet I fail to see their usefulness and how exactly they work: a) In order for URN to really be unique, there would have to be some central authority (similar to authority for domain names) where we could register URNs and that way ensure they are unique. Since there isn’t any such authority, how else do we make sure that our URNs are unique? And if we can’t. then what’s the point of

问题 I have read many articles about URI s, URL s and URN s, but I don't understand the diff in real examples. Could you take a few examples of URI and URL ? I think http://stack.com/first/index.html?submit=yes&action=go#second is URI, not URL, yes? Then http://stack.com/first/index.html is URL, because it's not so specific? Is this image is correct? 回答1: Here's a quote from the REST in Practice by J.Webber, S.Parastatidis, I.Robinson , that captures the essence of the differences: URLs and URN s

Appropropriate URN namespace now that X- is deprecated?

问题 As recently as 2002 the IETF was recommending in RFC 3406 that we should use x- prefixes for URN namespaces we didn't want to register, e.g. urn:x-acme:foobar . Now that the IETF has deprecated the x- prefix in RFC 6648, how are we supposed to construct URNs for namespaces we don't intend to register? As an aside, I note that RFC 6648 specifically mentions URNs: "In almost all application protocols that make use of protocol parameters (including ... URNs ...), the name space is not limited or

问题 I want to have JAXB-annotated classes which would be marshalled/unmarshalled to different XML namespaces . What I need is something like: <someRootElement xmlns="urn:my:ns1" xmlns:a="urn:my:ns2" xmlns:b="urn:my:ns3"> <someElement/> <a:someElement/> <b:someElement/> </someRootElement> How can it be done?
