Join Joe Marini for an in-depth discussion in this video XML namespaces, part of XML Essential Training.
…Alright let's wrap up this chapter by…talking about XML Namespaces and why they're used.…XML Namespaces have the form of the letters xmlns and then equal to some…character string and if you've used HTML before, you've probably seen this.…It usually appears on the HTML tag.…Now, the character string that goes inside that xmlns attribute…just has to unique, it's usually a URL but it doesn't…have to be. The spec says it just needs to be unique.…And in fact, the XML parser doesn't even try to access…whatever is at that URL, so why do you use XML namespaces?…XML namespaces are used to prevent…tags from different languages from conflicting with…each other when you try to use them in the same XML document.…
Remember X in XML stands for extensible so I can define…my own tags, now if I want to create an XML…document that includes tags from different tag sets, there's the potential.…For someone using the same name for a tag that I've decided to use in my tag set.…So let's take a look at an example.…Suppose I have an HTML file with a table in it, right?…
