Difference between XPath, XQuery and XPointer

Question

What is the difference between XPath, XQuery and XPointer? As far as I know, XQuery is an extended version of XPath

Answer 1

Well, I think XQuery is something worth to be distinguished. XPath and XPointer are almost the same and are used for XML nodes selection. XQuery on the other hand is quite a big extension of XPath. For example it gives possibility of declaring custom functions. So it's more something like programming language, which works natively with XML.
