You didn't give much context, but I think you are using the wrong
prefix.

~/src/xml/sandbox$ cat replace.xsl 
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:str="http://exslt.org/strings";

  <xsl:template match="/">
    <xsl:value-of select="str:replace('abcdefghi', 'a', str:replace('abcdefghi', 'b', 'B'))"/>
    <xsl:text>

</xsl:text>
    <xsl:value-of select="fn:replace('abcdefghi', 'a', fn:replace('abcdefghi', 'b', 'B'))"/>
