how to use substring-after-last()

I want to retrieve the name of the XML document i'm working on and I'm using the below Xpath.

<xsl:value-of select="fn:base-uri()"/>

and the resule that i get is having the entire path of the document i.e. like below

file:///C:/Users/home/Desktop/files/document/08192014/Raw.xml

so to get the only name of the XML document, in Altova the intelligence is showing some function substring-after-last(), i used this like below.

 <xsl:value-of select="substring-after-last(fn:base-uri(),'/')"/>

when i run this, i was getting some error as

Unknown function 'substring-after-last'
    Warning location: xsl:stylesheet / xsl:template / html / body / section / div 
    / xsl:value-of / @select
    Details
        XPST0017: The function call 'substring-after-last' does not match the 
        name of a function in the static context

please let me know how can i fix this problem and get the file name, also the same error is thrown for substring-before-last() and some other functions given in Altova.

I use XSLT 2.0

when searching online I've found that there was a template created and a call was done to that template, i want to know why am I directly unable to use the given function Thanks

The substring-after-last function isn't part of the XPath standard, it's an Altova-specific extension function. To use it you need to declare the Altova extension namespace with xmlns:altova="http://www.altova.com/xslt-extensions" and then refer to the function as altova:substring-after-last.

If you want to stick to standard XPath functions for portability then you can rewrite it in terms of regular expressions and use the replace function instead

replace(base-uri(), '^.*/', '')

The * quantifier is greedy, so this will match the longest possible substring from the start of base-uri() that ends with a slash, and replace it with an empty string (i.e. remove it altogether).
